% Increase of Recoil Factor -.375H&H over .458 WM?

So was shooting my newish .375 CZ 550 and this was my 5th outing with it, recoil especially offhand isn't really that bad... What kind of a increase is involved with a .458WM? I would buy another 550 and drop it in another BC stock. My selection of bore size would then be complete but I still want something useable and useful!!

All depends on the rifle and the load. My #1H is a 458 WM and, while it's a kicker, it's not unmanageable from the bench. Stout, yes, but not unmanageable. But if you put the same load through a CZ 550 it will be less exuberant due to the increased weight )pretty sure that the 550 outweighs the #1 but I could be mistaken). When I was shooting the #1 a lot I realized, when I crawled up behind Rosie's 223, that I was gripping the stock pretty hard. Not flinching, but I subconsciously knew to hang on tight.

Having shot the 375 and 458 I would say that, in the rifles I used, the 458 was harsher. The 375 is generally pretty easy to shoot for people who can handle the stouter hunting cartridges...maybe a little more work for people stepping up from the short-action chamberings.

I've had all 3 rsm's 375 is a joy to shoot, couple boxes of ammo at a time easy. 416 was surprisingly not bad either, i sold my 375 because it didn't feel very big bore , bought a 416, was a little step up but not much. 458 is a pretty big step up. After 10-15 rds I find I'm ready to call it quits. At least trying to shoot accurately.

That's because they're about a pound heavier than they needed to be. But fine rifles. I have one in the 416. Not sure if it kicks harder than my #1H 458 but either way they're not bench rifles for newbies.
 
My 458 kicks more than any 375 I've used
I load 400-405 gr bullets to 2400 fps and it's not bad. Prone starts to get to m after 15 or so shots simply because prone I don't have any meat on the top of my shoulder
9 shots with 500 gr solids at 2200 fps really slowed my arm movement significantly
Off hand it is still quite manageable

I loaded some 300 gr Hornady hollow points the other day. At 2263 fps it was less than a 410 shotgun. At 2560 fps it was like a 3" slug from a 410

The impact on the berm was quite impressive and the hornadys stayed together for the most part

458 wm is a hand loaders dream. Big pellet gun to elephant stopper
 
45's are a lot of fun! I just got a supply of Speer 400gr SPFN bullets for my 45-70 Marlin that I will have to try in my 45-70 Ruger, 458 Win. Mag. and 458 Lott.

Speer advises the 400gr SPFN isn't constructed to penetrate properly on large Bear so it must have a relatively thin jacket like the Remington 405gr. I would expect the Speer 400gr to perform like the Remington 405gr.

Here's a Remington 405gr bullet recovered from a Bull Moose I shot with a 45-70 Marlin. A rear quartering shot that broke the close shoulder, severed the spinal chord and lodged in its neck - dropped DRT. Impact speed was about 1600 fps, and total penetration was about 18".

Note the core slipped from the jacket which would also likely happen with the Speer 400gr (not a core-bond Hot-Cor type bullet). But worked just fine for me.

That's a "well behind the shoulder" bullet for deer out of a 458 WM or Lott. 1600 isn't particularly hot for a jacketed bullet out of a 45-70 (Speer lists many loads in the 2000 fps neighborhood) and 2400 out of the 458 WM. They don't list a load from the Lott though they do for the 350 Mag tip which, to me, indicates that it is a woefully poor choice for velocities getting into the 2500+ range. Given that the core slipped with a similar bullet in what amounts to a medium-resistance shot, I wouldn't push them any faster when there are a dozen better choices out there that will hold up properly on similar shots.
 
Muzzle speed was around 1850 fps which is near maximum for a 22" barrel 45-70 Marlin, and the Bull Moose was about 75 meters away which goes to show quickly this blunt bullet loses speed. Should work fine on heavy game 200+ meters away launched at about 2700 fps from a 458 Lott. :)

But since the 400gr Speer has a thin jacket it might disintegrate upon leaving the muzzle at that speed as 300gr HP bullets do.

I've been looking for a decent deer bullet for my 458 wm since rem bulk bullets seem to b in short supply lately
Think the 300 gr hollow point from Hornady will b a winner. Book loads are almost identical for my velocity even though I've got a 26.5" barrel. Or I have the slowest chronograph on the Internet lol
But we're getting off track

The 458 can be a gentle giant or a miserable ##### to shoot
The 375 hh guns I've shot were much more tame
 
Current standard hunting load for my 458 Lott is the 300gr TSX or Hornady 300gr HP at 2500 fps MV, a mild load. Both shoot to approximately the same impact point at 100 yards.

I've used the 300gr TSX loaded at 2600 fps MV in my 45-70 Ruger No.1 and got a 1 shot DRT kill on a 6x7 Bull Elk at 150 yards, so 2500 fps MV in my 458 Lott is fast enough. :)
