I fired a 375 H&H years ago along with a .458 Win Mag. I could not tell the difference because they both hurt. I fired 4 rounds of the .375 then 2 rounds of .458 and tenderly handed the 2 guns back to the owner. I asked him for what purpose he wanted such large rounds. He said the .375's were for an Alaskan brown bear hunt and the guide told him that that would be a minimum round that he would need for a big Alaskan brownie. I then asked him about the .458 and he said he had it in his head he wanted to go on an African safari and they only carry double rifles there. But he was going to take both rifles with him. Evidently money was no object at the time. I tried to roll with the recoil but there is no rolling, it's simply taking the abuse. The biggest rifle I ever had was a .338 Win Mag and I can attest after 20 rounds of firing that rifle, it's all I wanted. Firing the bigger rounds made me a total believer. But as they say, if you got the money honey, I got the time. I would be a gun bearer years ago but today I would have to push them in a wheel barrow and it wouldn't be for very long. BTW he did get his Alaskan brownie but I never knew if he ever went on safari.
