In other calibres they do so hopefully in .375H&H soon. We can only hope.

Are you seeing high pressures. I like Hornady as their ammo seems consistent, brass seems good and it is usually faster, without pressure signs, than other ammo dure to their powder blend. So, I like their fast ammo.

I don't need high velocity to make 400 gr bullets work. And my fragile retinas don't need the extra recoil.

The last time I tested .375 H&H factory ammo it was Federal's Premium Safari 300 grain A-Frame.
Federal promised on the box a MV of 2,450 fps. From my 24" barrel 10 rounds produced an actual MV of 2,447 fps. Not too shabby. The SD & ES numbers were horrid, but out to ~150 yards, it doesn't matter that much on big vitals.

If I ever come across a box of that S&B SP I'll buy a box and give 'em a whirl.

The .22 Mag blew up in my 455 with factory barrel. The primer ruptured, the blast set off another one or two rounds in the magazine, blowing up the magazine in my hand as I was holding the rifle right there. Magazine destroyed, luckily hand was OK. Bad headspace? Who knows, did not measure but other ammo worked flawlessly.

Rimfire!?
Wow!
I am glad it ended well, for your hand!

Yes rimfire. Still have one or two cases somewhere. I then fired more of the same ammo but single-fed, with no magazine and no hand below the magazine shaft. Few more blew up.
