i shoot top end loads for the 375 win with 200 grain bullets. it is a game getter as long as you stay in range limitations. the recoil as noted on other sites and post can be an issue if recoil sensitive. I would shoot 10-20 rounds per session with it and could fell that i had been shooting a big gun, however it wasnt enough to make me stop, it was just the amount i was shooting for the day. I left it with Chuck Williams (Willicd76) in texas after we hog hunted his place and he installed a brake. I am sure you could shoot it all day now as it tamed the recoil to near 357 mag levels. if i were to do it all over again i would get the brake installed at manufacture. It is my favorite contender barrel for hunting big game. I am restricted to straight wall cartridges in iowa and am very pleased with it
