For the inspiration of this article, go to my blog on October 24, 2024 entitled: “There’s a time to Shoot, and a time to NOT!” In all my reading on black bears, I’ve yet to see words like “gorgeous”, “beautiful”, “awesome” or the like! That is, except for my own post on that date. While the rifle involved in that fall bear hunt was my .375 H&H, the Ruger No.1H in .458 Winchester Magnum had its turn at the same location a couple of years earlier.
I’ve described that bear since with carefully chosen words that really fail to attribute the glory of that bear’s worthiness. As described in the blog referred to above, I was unable to get the camera from its case held by a strap around my neck with the .375 H&H held in one hand, and I deeply regret that. So I attempted to find something on the Net by way of example. It’s not perfect but gives an idea of what I encountered.
Anyway, that experience and that beautiful beast (At the time I said: “In the +400 lb class”) – in reflection, after 40 years of continuously hunting black bears – it was by far the most gorgeous and largest bear of a lifetime in hunting them – I’m now certain that he was a +500 lb bear, but not like a bowl of jello! And his size didn’t grow with more time and imagination! I’ve taken into account the breadth of his shoulders and chest – at least 3 feet – and his unhurried stride, having never before seen such a beast – both massive and beautiful!
The closest pic to “my bear” I’ve found. Do you recall the large deadfall that blocked my trail in to the bait near the end of the spring hunt of 2024? Looked quite alike to that one!
< The one that blocked my path to the bait sight about 75 yards beyond. At first I thought about sawing out a 30″ chunk. But it’s an old hardwood about 15″ thick and I’d sold my chainsaw with our park trailer several years prior. Instead, I put the bait bucket and rifle over first, then sat on it swinging one leg over at a time! That’s what I was doing here:

But, I have no plans to redeem myself and go hunting again in 2026 for that spectacular bear using my Beautiful Beast, the Ruger No.1H in .458 Winchester Magnum! Resting in the .458 loaded ammo box are the vintage 400gr Colorado Custom RNs, sighted in at 50 yds at 2257.4 fps/4525 ft-lbs.

Facing up to reality and the facts of life at +90 years doesn’t permit taking risky chances! But wife’s condition permitting, it will again go to the range . . . . and likely spend some hours in the general area of where that beautiful beast paid me a brief visit on October 15, 2024. But what if we have an accidental meeting, would I shoot him? No, for the same reasons as given in 2024 – unless he forced me to defend myself. My Beautiful Beast will be loaded with either the 400gr Colorado Customs at ~2250 fps or the 300gr TSX at 2750 fps. My goal will be to stay fit for the game. Should I run into a really young bear, I might “miss on purpose” to give him a scare and some training! But if he’s in the 140 lb class, I might “not miss on purpose”!
My .458 is a Beautiful Beast!
It was recently taken out of its carry-case, and I was reminded of its extraordinary quality and features: The first was its balance and handling qualities that belie it’s overall weight – it handles like a carbine. It’s only 40.375 inches in overall length (40 and 3/8″) and balances where I hold it in one hand. Its length-of-pull (LOP) is 13.75 inches – perfect for me! And the scope – a Nikon 2 – 7 x 32 mm – is firmly secured at exactly 4.5 inches from my eye when the rifle is normally brought to shoulder. It’s overall handling is outstanding for a 10.65 lb rifle fully dressed and ready for a fight!
Too heavy? No, it doesn’t seem like it – in its compact but sturdy format.


My carry hand (left or right) fits perfectly where it’s supposed to: On the forearm just in front of the action, and there it balances perfectly! As would be expected, it has a very heavy 24″ barrel that’s Mag-Na-Ported. That’s where most of its extra weight comes from.
It’s not tiring to look at or boring to load when handloads are up for trial. One could never exhaust its potential: There are literally thousands of possible handloads for anything from tin cans, bottles of water, grouse in the bush, groundhogs, fox, coyote, hogs, deer species to wild and very dangerous – and all have been taken at one time or another around the wide world – if a handloader and adventurer.
The sweet bullet weight might be 400grains at anything from 1600 fps to 2600 fps. I’ve tested bullets from the 250gr Hornady MonoFlex at 2650 fps (+3000 fps possible) to the 500gr Speer GS at +2300 fps. In additiion to those two, I’ve handloaded 300s, 330s, 350s, 400s, 405s, 450s, 465 cast, 500s, 550s and 600s. The Barnes 400gr X-Bullet made 2590 fps from my Ruger No1H.
It can be handloaded to duplicate BP and .45-70s on up to 6000 ft-lbs from 400s, 500s and 600s . . . . It stands alone in uniqueness and versatility due to its cartridge case design, scores of bullets and molds available, dozens of propellants that will work -some old and others new – and rifles from several manufacturers both old and new. And while bolt-actions are most common, yet there are doubles and single-shots for savvy hunters of varying economic status, ages, knowledge and experience!
FEATURES: of the Ruger No.1H in .458 Winchester Magnum as seen on the Header.
- Single Shot: Farquharson Falling Block action type noted for strength and reliability.
- Exceptionally strong action: They don’t break or fall apart with long-term use. They can easily handle anything a bolt-action can, and then some! As well, usually COL can exceed SAAMI specs allowing the use of more powder with bullets seated longer than normal.
- Long Seating of bullets: This allows the cartridge case more flexibility in the use of propellants and bullets. The .458 Win Mag chambered in a Ruger No.1H, or other strong single-shots, can attain whatever a .458 Lott can achieve in a bolt-action repeater of the same PSI and barrel length – or surpass it due to the extra-long freebore.
< The 350gr TSX as seated for my Ruger No.1H at 2750 fps/5876 ft-lbs
- High PSI of loaded projectiles: Today’s SAAMI standard is the same as the .458 Lott’s at 62,500 PSI . Originally it was 60,000 psi.
- Dozens of bullets available over the counter, and dozens more from molds: All major bullet makers produce .458-cal projectiles for both the .45-70 and .458 Win Mag. Those made for the .45-70 find useful employment in .458 Win Mags. I have hundreds from 250s to 600s.
One lineup – I have others. From L to R here: 480 DGX, 465 hardcast, 450 AF, 450 X, 405 Rem, 405 WW, 400 Hawk, 400 Barnes Buster, 350 Hor., 350 Speer, 350 TSX, 350 Hor (2), 330 Barnes Solid, 325 Hor, 300 Hor, and 300 Sierra.
- Almost any mid-range propellant will work: from A5744 to CFE 223. But the best of those are found near the middle: H4198 to A2460. My favorites are H4198, H335 and H4895.
- Has international experience of excellence in harvesting large wild beasts with reputations of killing their hunters.

- Tough with minimum maintenance . . . .
- No extravagant costs . . . .
- Compact and handy . . . .
- Beauty in proportion . . . .
- Companionable:

- Comfort and protection . . . .
- Regular use makes it a favorite . . . .
And yes, a scope and sling make it still more companionable and useful. My scope is a favorite Nikon 2 – 7 x 32 (sadly, no longer available). A rifle scope for such as a .458 Win should NOT be overly large and heavy with 50mm objectives. That would only add unnecessary weight and upset its balance and handling.
Good all around bullet weights would be premium 300 TSX’s, 350 Speers and TSX’s, 400s and 405s, the 450 AF and 500 DGXB. The 400 Hammer (expanding) could be a 1st consideration, though I’ve no personal experience, and they’re unobtainable in this area. Premiums aren’t cheap for plinking, and unnecessary for most game in .458-cal. Cast bullets are usually the most economical, and there are still some good C&C bullets out there that will do an excellent job on most soft-skinned game, depending on construction, range and MV.
Two cases for loaded .458 Win Mag ammo. In the background is a case of original FEDERAL 400gr TBBCs for the .458. I’ve fired 14 of those in tests, one of which had been disassembled into its various parts: case, powder and bullet for analyses. Then reassembled and shot for verification compared to the other 13. Ten of the fourteen have been reloaded with 300gr TSX’s over 75 grains of H4198 for ~ 2750 fps/5037 ft-lbs – not a max load, but good for North American hunting of medium to large and dangerous game within a reasonable range of about 300 yds. The others loaded in the green box are (top right corner) 400gr Colorado Customs and two 400gr Hawks at ~ 2250 fps. In the left half of the box are a couple of 600gr Barnes O, a 450 AF, one 500 DGXB, some 405 Rems, two 400 Barnes Busters and, finally, four 550gr Woodleigh Weldcors. Then, of course, quite a few that have been fired, including 4 of the original Federal 400 TBBCs.
Did I miss anything?
Till the next. . . .

<One of the four trips to the “Far North” of Northern Ontario. The exact location for camping on those other trips, and the only one with more than one partner. Meet Dave and son Jon, on my third trip nearly a decade later than my first trip with a single partner!
< Mike is second from left, on a bear hunt in Northeast Ontario, with my oldest son Brent on far left, myself with orange hat and close friend on my left, Bob (now deceased).
< My old original – it still works!


There’s a place for a short, handy and powerful weapon, and multiple quick shots! This one fires the 12ga CHALLENGER slugs (492gr Brenneke type) at 1550 fps. It’s my backup for a wounded bear in thick bush!
This is a scene from a vast unspoiled wilderness area of Haliburton Highlands Crown Land. I knew it well. That was my CZ 550 in .458 Winchester Magnum. I was hunting as signaled by the orange vest over my jacket and the orange head gear. There was both a light 1″ nylon sling and a light weight Burris fixed 4x scope with a long 5.5″ eye relief. The load was a 350gr Barnes TSX at 2750 fps/5877 ft-lbs. I typically had several tickets for game, but I was primarily on a scouting mission. There was a light skiff of snow and bare bushes that signaled mid to late fall. And the velocity of the 350gr at 2750 fps allowed an effective range to 400 – 450 yds for bullet expansion purposes. This was a solo hunt. At a later date I did shoot a bear in that area using that load but I also did have company.
< The same rifle, sling and scope as above – this time 1000 miles/1600 kms from home! And, yes, the same load on that moose hunt. There were clear cuts for over 1 km. And I had a mature partner who took the photo. Yet, we were mostly hunting solo – separated by 1/2 to over a mile apart! He on his ATV and I on my two feet! I covered areas that he couldn’t, and saw details he didn’t – but also visa-versa!
<Son Phil and his Rem 700 in .338 Win Mag – a great choice for a moose hunt. If he had not been there, we would not have been homebound near midnight of the next day! A solo hunt for a bull moose isn’t highly recommended, especially at 1000 miles from home – too many things could go wrong, even bad things that could threaten personal security! While I’ve done solo hunts for bear, deer and smaller game, an adult moose can weigh over 1/2 ton as in the pic above! PHIL’S FIRST COMMENT WAS LIKE: “WHAT NOW?”
