. . . . . . . excluding thick-skinned African DG.
After a number of years in my life-long hunting career, I believed so. The only rifle cartridge that I’ve owned more rifles in was the .45-70. Handloaded, both have had a very strong appeal: around 4000 ft-lbs from each while employing significantly distinct projectiles: .458-caliber heavy bullets with rather blunt profiles from .45-70s at modest speeds; and comparatively much lighter weight, sleek bullets with high BCs and very fast speeds from the Winchester .300 Magnum. . . . The best of both worlds! What one couldn’t do the other could.
For large, tough and potentially dangerous game, up close and personal, I’d choose the .45-70 firing an appropriate 400-grain at 2100-2200 fps. Past 200 – 250 yds, the .300 takes over. But the .300 is no slouch up close and personal shooting a 200gr premium bullet at ~3000 fps!
So then, a handloaded .300 Winchester Magnum is not a bad choice for a brown bear in Alaska to a western antelope in Alberta, to an eland on safari. That’s a pretty broad and deep hunting environment. In addition, of course, it equally qualifies for sheep in the mountains and elk on the plains.
It has also been successfully employed as a sniper rifle and in pro target competitions. And it not only is highly regarded for all of the afore-mentioned activities, but with such a pedigree it is still very prominent in the midst of multiple modern pretenders that make claim to better credentials, such as the .300 RUM.
Its successes are related to the timeing of its introduction (1963), the Winchester Company, the M70 rifle, its case capacity, and .308 caliber – the favorite of Americans. The cartridge case is an elongated .338 Win Mag that preceded it by five years in 1958. But it has a shorter neck than the .338 which initially brought it under criticism by some gun writers. Personally, I’ve never found that as a handicap, and never experienced any difficulties in consequence. Today, it’s rarely mentioned by writers or users.
Bullets and Ballistics:
Though there are component projectiles for handloading as light as 110gr for varmints, and 125gr for small game which may be used in the .300 Win, that is far from it’s intended purpose. Usually factory products start at 150gr and go up from there to 220gr, but the highest demand for commercial products are 180s and 200s. And not surprisingly, that is usually the bullet weights employed by handloading hunters as well. While there is a 190gr ABLR and a 210gr ABLR with high BCs of .597 and .661 respectively from Nosler, the legendary 200gr Partition with “only” a .481 BC, is still a favorite for moose hunters where most shots will be this side of 400 yds. But for a potential longer reach to 500 yds the 200 Partition is still capable for that task. But a potentially better Nosler is their newer 200gr ABLR with a .588 BC, extending usefulness on large bull elk to +600 yds. In fact, the .300 Win Mag is a favorite for just such applications.
So, the point of all these proven results is to state conclusively that the .300 Win is one of the best of the best for world-wide hunting.
And to add a personal sentiment: If I were to do it all over again, among all of the numerous .300 mag contenders available today, I’d still choose the .300 Win!
Why?
Because it can do the most within costs, weight, choices of rifles and components, where – for example – a .30-378 Wby Mag adds nothing practically with +200 fps except a burnt-out barrel in less than a thousand rounds! And it has less recoil than a .300 Wby if rifles are the same weight. And with barrels of the same length, the difference in ballistics is insignificant. How do I know that? Because in addition to six .300 Win Mags, I’ve owned one in .300 Wby with a 24″ barrel.
Added to that was one in .308 Norma Mag with a custom 21″ barrel. From son Phil, I had gifted to me a Ruger 24″ .300 Win Mag barrel that was given to him by a friend who wanted a .300 Wby barrel on the Ruger rifle. That Ruger 24″ barrel was recut by my “smith” to fit the .308 Norma, and lost 1″ to become a 23″, .300 Win Mag custom rifle. Eventually, it got sold, but 3000 fps from 180s was usual. I still have that 21″ .308 Norma Mag barrel. After many, many trials from various combinations of bullets and powders, 3000 fps was attained from 180s as a .308 Norma Mag (All .300 mags are .308-cal).
Barrel lengths:
. . . . . . make a difference!
While most factory .300 Win Mags have 24″ barrels, it’s best results are from a 26″, which may be up to +100 fps. That, of course, depends on handloads and the bullets and powders in use. One of the half-dozen had a 26″ barrel – a Browning A-Bolt SS, LH. It was fast! And very accurate – mostly 1/2 moa! 3200 fps from 180s and +3000 fps from 200s. And the rifle was very comfortable to shoot without a brake.
Speaking of which, I’ve never understood the fears of those who reject the .300 Win on the basis of its supposed recoil. My first – a Winchester M70 – was too heavy for my liking, so got traded on a SAKO .338 Win FS. The whole Win 70 package in .300 Win was more suitable for a .375 H&H, or even a .458 Win Mag! But then, I’ve had so many rifles with far more “kick” than a .300 Win, that I treated them like a .223 Rem, and could shoot them just as well, whether from offhand or from the bench. When I got my first – the M70 I mentally prepared myself for a “hard-kicking” rifle! It didn’t happen. In fact, when a much younger hunter/friend who used a .308 for most things, asked to give my .300 a try, he was surprised that the recoil was far less than expected – and I never “down-loaded” that rifle to ease the imagined pain.
After the .338 Win in the SAKO FS, at 35 – 40 ft-lbs of recoil, the .375 H&H M70 that followed seemed “normal”! Of course, it was much heavier – in fact, like its predecessor, the .300 M70 – it had a barrel of the same contour as the M70 .458 with a smaller bore that made it heavier than the Win .458! In those days I was shooting hundreds, if not thousands of handloads in .338s, .375 and .45-70s! In consequence, a .300 Win Mag seemed like a varmint rifle by comparison! So, “felt recoil” is a comparative thing, and mostly mental! True, when we get to the real Big-Bore heavy-hitters, they can do damage to the shooter if he/she isn’t adequately prepared for it! But not a .300 Win Mag! Recoil is about 35 ft-lbs compared to about twice that from a .458 Win at 60 – 70 ft-lbs, or a .460 Wby at +100 ft-lbs being 3x that of a .300 Win. So, it is really a matter of mental gymnastics and perspective.
Did I need a .300 Winchester Magnum? Well. . . . Yes! A .300 Win is not necessarily more costly than a comparable .30-06, and for a particular hunt, say for a bull moose, I’d not specifically choose a .30-06 when a .300 Win has a 150 yd advantage and will hit with more force than a .30-06 at any range! So, based on how I look at and evaluate matters, a .300 mag is the better all-around choice! It’s simple math and logic. Quite a few years ago I swapped 3 rifles for two. The two I had in mind were identical in most features except in cartridges and bores: Both were Browning A-Bolt magnums with 26″ SS barrels and actions in left-hand, and clip magazines attached to their floor plates that could be removed and carried in your jacket pocket until needed – or a second one of each could be purchased and kept loaded in your jacket pocket. One was in .300 Win Mag and the other a .375 H&H mag. At the time I felt that would be sufficent for any big game I might ever hunt, including Africa.
Things don’t always turn out as planned as the .375 H&H had an off-center bore from the factory. But it was relatively light and very fast – as was the .300 Win Mag. Not a bad plan but the .375 H&H was returned for a .338 Win in an identical rifle to the .300 Win – so eventually the 300 “went down the road”, and the .338 was rechambered to a .340 Wby which made the others obsolescent. With the passing of time, I added another .300 Win as a backup for moose hunts, and the .340 was sold and replaced by the 9.3 x 62 Mauser for moose and big bear as most of those hunts were closer to home.
A .300 Win as a backup? Yep, here and there:
< This “trophy” was shot from my ladder-stand in the background line of trees. My backup to the 9.3 x 62 was a .300 Win in a Savage bolt-action.
< and here on a moose hunt to the “Far North” of our province, the same Savage in .300 Win Mag was the backup to my CZ550 in .458 Winchester Magnum.

*Assuming an able rifleman, this load shot into shoulder, heart or lungs should immobilize within 50 yds a 1/2 ton moose at 600 yds, though most are shot well inside 400 yds.
What about an Alaska/Yukon moose that could go 3/4 ton? I ‘d take a bigger bore rifle and limit shots to ~400 yds, unless the only chances were a bit longer. And a .338 to .375 would be my choice in magnums – .340 or .375 Wby or thereabouts.

It would be quite challenging to improve on a 2 rifle safari of a .300 Win and a .375 Wby or H&H.
If you prefer the .300 Wby over the .300 Win, that’s OK by me. As stated, I prefer the .300 Win because the rifles, cases and loaded ammo are generally less costly and more readily available, especially in out-of-the-way places.

< That was my .340 Wby Mag. My son, Phil, and I were a long way from home on a moose hunt – I was in my sixties. The load was a 250gr Partition at 3000 fps = 54 ft-lbs of free recoil.- more than twice that of a .30-06.
< Add 14 fps for correction to the muzzle at 5 yds from the Chrony.
< The 300gr Sierra BT on the right and the 300gr TSX on the left. At the same COL we can see how the Sierra could accomodate more powder without compression in addition to a much higher BC of .480 vs only .357 for the 300gr TSX.
<The 250gr Barnes TTSX crimped into the top cannelure for max COL.
And there’s the infamous blind still in place after fifteen years!
< This is physics. I wouldn’t have known with any cerainty what the 405gr Remington was doing from the muzzle of my 1895 Marlin in .45-70 without the chronograph. Then other calculations were made based on the claimed BC of the bullet: Its trajectory and energy at various ranges. The distance between the Chrony and the muzzle of the rifle was 15′, so based on Remington’s claimeded BC of .281 (based on their factory load for the 405gr, its trajectory and energy at various ranges), I added 14 fps correction to 2101 = 2115 fps/4022 ft-lbs. I shot a nice bear with that handload at 97 yds downhill from blind to bait barrel. It was a going-away shot into left flank that made exit just behind the right shoulder. Impact velocity was 1835 fps/3028 ft-lbs. That was the physics. A bang-flop was the result.
<This was the bait-barrel at 97 yds. The bear was leaving to the left.
< I never saw a deer track here, though moose were travelling over this mountain. On the far side was a sheer cliff drop-off, straight down. We were in Ontario’s Far North, 1000 miles from home – still in Ontario.
This is quite typical of my hunting area for the last four decades. I was seated in that chair because in front of me was a ground blind for bear hunting. It’s on a ridge about a hundred yards or so from a main highway. Actually, I was deer hunting with my Ruger No.1 in .45-70 loaded with the 300gr Barnes TSX at +2600 fps. The location is about 2 miles (3.5 km) from my main bear-bait site on the opposite side of the highway, on a side dirt road.
Killed a good bear with one of these from a single-shot NEF .45-70.
< My first bear with this from my first 1895 Marlin: a 400gr Speer at 1865 fps. Range was 100 yds.
< Not my moose, but very similar to an experience I had back in 1994 – 1995. I was watching a bear bait in a remote part of our province, and Norm Easto was my guide/outfitter. A bull moose like that showed up behind me at about that distance. I stood, facing him with my 1895 Marlin, and shouted “Get out of here!”. It was spring, not during the fall moose-hunt season. But he had a full rack and left though rather grumpy! I never flinched as I raised my rifle and pointed it at him!
I carried my .375 H&H for bear last year because he was dominant for the area and weighed 500+ lbs. And ideal conditions weren’t possible given the terrain, and the bear was on the move when I finally saw him for about 20 seconds. But I would have fired at 20 -25 yds with crosshairs on him if I’d wanted a trophy or 500+lb bear for whatever serious reason – which I didn’t. But I felt ample protection from that .375 H&H (300gr SBT at 2674 fps/4762 ft-lbs). At 25 yds the 300gr would still be making over 2600 fps, but the angle would have been less than good on a mobile bear! Yet a 300gr at +2600 fps would have done him no good even from a high-angle shot. That’s why I choose “more than enough” for ideal conditions – because they might turn out to be far less than ideal! If I’d let that bear see me (he did smell me) what would his response have been? I didn’t know and didn’t want to find out because I might have had to shoot him, so I left the scene. Nonetheless, I was happy for my choice of the .375 H&H. After all, the .375 H&H is said to be a “perfect choice” for lion, the largest of which will weigh less than “my bear” of 2024! But some say that a lion is “dangerous game” while a black bear is only “potentially dangerous”. Tell that to the Alaskan 60 year-old man who was recently killed just outside his home by a yearling black bear that weighed 70 lbs! That problem being that he can’t hear what you’r saying because he’s dead!
< 5 gal bait buckets that bears carry off full or empty.
This is a 15 inch thick hardwood that fell across my access trail to last year’s bait setup where the huge dominant bruin was attending! It happened near the end of the 2024 spring hunt. I’d sold my chain saw, and a hand saw would have taken hours of muscle power to take out a piece a yard wide! Did “my bear” do that? In all likelihood, yes! Since I wasn’t there when it happened, I can’t be 100% sure, but knowing what bears can do, and do, I’m at least 2 out of 3 guesses that it was “my bear”! That’s 67% sure that a big bear did it!
< Ken’s rug from the 400 pounder.
This is 1/2 hr after sunset at a different location several years later. I was just getting ready to leave my stand. That leaf in the middle blocks the bait barrel at 115 yds. A young bear had been feeding at it with momma bear keeping watch in thick bush to the right. Once in a while she’d stick her head out. After I’d taken this pic, I descended the ladder to go to my van 200 yds away. The leaves were illuminated by the flash on my camera.
<From the Net.


< Six 400gr Speers from three distinct loads at 50 yds.
<Identical to this.
< A loaded .375 H&H cartridge in Remington brass on the right. The cartridge case on the left was formed from a .375 H&H Rem case – necked to .338 in my .340 die and then fireformed in the .340’s chamber. The chamber was originally a .338 Win Mag but reamed to a .340 by gunsmith Edward Von Atzigen with the Weatherby freebore.
< L to R: .35 Whelen loaded with a 225 Partition; .375 H&H loaded with a 300gr SBT; and a .458 Win Mag loaded with a 400gr Hawk.
< Eastern Wolf – yep, I’ve had ’em that close . . 
A sow with her cub had gone down this trail just ahead of me, and then left the trail into thick bush. “Where are they?” They were protected by law, and I could’ve only used my Ruger 96/44 lever action had she attacked me! It was the fastest rifle I’ve ever owned for multiple shots, and has been replaced by a Stevens’ 12ga tactical pump firing 492gr CHALLENGER slugs at 1550 fps from the short 18.5″ barrel. They are used by both military and police. Those slugs are Italian made and loaded into shells in Quebec. They are very accurate in smoothbores and devastating at short ranges. At times this is toted instead of a rifle – a big-bore’s Big Bore!
< On the left, 50 300gr TSX in .375-cal, and on the right, 50, 300gr Sierra BT in .375-cal. Note how the TSX box is significantly larger to contain the 300gr TSX’s. Copper is much less dense than lead, in consequence of which all copper bullets of equal weight are much longer than those whose weight is mainly from a lead core in the same caliber. If COL is equal (in my .375 H&H COL is nearly identical) then less room for powder is available when all-copper bullets are employed. The Sierras have a much better BC at .480 so can be useful at significantly longer ranges than the TSX with a rather poor BC of only .357. On moose (up North) I’d choose the Sierra 300gr over the TSX of equal weight. The same for caribou and sheep. What about the 270 LRX? It can be started faster at up to about 2800 fps? Yes, but it has a poorer BC of only .449, less momentum all the way to termination and a relative poor SD of .274 compared to the 300 SBT at .305. Better construction for the all-copper 270? That would be speculative till proven one way or the other. I deal in facts, not speculation or hearsay.
< This is a 200gr/.35-cal Rem Corlokt bullet that killed a good black bear as it walked under my friend’s treestand. He said: “That bear didn’t move 5 inches!” No, it’s not a Partition or a Barnes “wonder bullet”! But it’s a favorite among Maine’s bear hunters using lever-actions in .35 Rem. MV was about 2100 fps from a handload.
<The spring bear went 270 lbs after field dressing. The rifle a Marlin lever-action carbine. As a fall bear it would have gone over 300 lbs.
<This was found in the offside armpit of the bear. It retained 90.5% (362 grs) of unfired weight! And here’s the bear:
< Now there’s an unhealthy looking bunch! I’ll not try to shoot those again. Actually, they were all .458-caliber fired into various types of media. Some look like they could take on a Cape buffalo and survive, and others no-so-much! Going clockwise from the top:
<350gr TSXs/.458 from the 100 yd berm behind target.
< Partitions: L to R – two 250gr/.338 from moose. One 286gr (.366) from bear.
< 416s/400grs that tumbled in media. (not mine) These were Hornady 400-grainers from a Ruger No.1 in .416 Rigby. The fellow shooter at our range said the load was for whitetailed deer at a modest 2200 fps. I was shooting my Ruger No.1 in .45-70 LT. They were also Hornady SP RN in 500gr at about the same speed as the No.1 in a Rigby .416 shoooting those 400s. He asked questions about my load and then challenged me to shoot his rifle as he was certain I couldn’t handle the recoil. I agreed if he’d shoot mine afterwards . . . He agreed. So I shot his first: a 400gr at ~ 2200 fps from a Ruger No.1 that weighed ~ 10 lbs = 42 ft-lbs (about). He then shot mine over the Chrony that recorded 2186 fps (corrected to MV = 2200 fps) at 74 ft-lbs recoil. It was almost like he went into trauma! The extreme difference in recoil was because of both the distinction in bullet weights (at about the same velocities) and the weight of the rifles: Mine at 8.3 lbs and his at 10 lbs.
< My former Ruger No.1 in .45-70 LT. My gunsmith gave it a long throat allowing bullets to be seated “long” granting more space for powder. It was the equal of a .458 Win with a 22″ barrel. It was my favourite rifle for nearly two decades.
The point of this photo is to show how compact the Ruger No.1 is compared to the 1895 Marlin. Both are .45-70s with 22″ barrels. Yet the Ruger No.1 (LT) can fire a 400gr SP to 2400 fps, while the Marlin struggles to make 2100 fps from a 400gr FP. Those are, of course, best handloads.
< Add 14 fps for correction to the muzzle.
<Here it is before being traded on the Ruger No.1H in .458 Win Mag.
< Two .458 Win cartridges. The one on the left is loaded with powder, primer and a 600gr Barnes Original at 3.7″ COL. The one on the right is a simulation without primer or powder, but the 600gr Barnes seated to 3.908″ COL. If you’ll note the black ink ring on the bullet at the mouth of the case, that was to see if that bullet, with its large bulbous nose, could be seated 1/4″ and still be chambered without pushing the bullet back into the case. The cartridge at 3.908″ COL was chambered, locked in place by the lever, and extracted with normal results without moving the bullet deeper into the case.

< My Ruger No.1H in .458 Win, literally loaded for bear in 2020. That’s not far from where I hunted bear over bait in 2023 – 2024.
<For Africa’s largest: L to R: 600gr Barnes Original, 550gr Woodleigh Weldcore SN, and 500gr Hornady DGX-Bonded. Yes, I’ve shot them in my Ruger No.1H.
