45-70's trapdoor and a Marlin 1895, little babies.
Worked up loads in a friends 458 Win, Does get ones attention.
I've owned several 375 H&H, no problems bench or other wise.
I built a custom Mauser in 416 Rem. That thing was nasty, I shot it at 25 to check my bore sight and the bench to fine tune was brutal.
I've owned many MAgs at the same time, 264 Win and 270 WY. The larger bore 270 seemed to recoil less.
Recoil seemed less for the following;
338 less than a 300 Win mag.
340 less than a 300 WBY.
Maybe it was just me but I felt bore size impacted recoil more than bullet weight.
I once had a 3 screw Ruger 7.5" in 45 colt. I had about 200 plus Genuine Elmer Keith 255 grain tank stoppers loaded. I sold the pistol and told the guy I was going to shoot my ammo up before I handed it over. He had never shot any nor tried it. Ok with him since I said it was pat of the deal. Around the end of the 2nd box I felt stinging on my rt palm, a dime size blister had formed and twisted off from the back and twist up to the rt recoil.
I put on gloves and finished, My hand felt like some one had been whacking it with a pool que. It was ok soon, but hurt that night.
A friend had a 30 Herret and a 35 Rem BBL for his TC, he won his class in the state championship on the hog chicken steel plate thing. HE hunted with the 35 REM, I fired it a few times, you can feel the wrist bones compressing. He wore a padded glove in shoots with the Herret. He reloaded, they may have been lowered too.
I've shot a few african rifles, again what I perceive is the bigger the bore the bigger push one gets, a similar size round with a smaller bore gives a harder kick.
