I've owned and shot many big bores. Everything from 375's up to the 458 lott. I've owned 3 lotts and fired many rounds. The one that is the worst is my 375 rum. In factory trim with full house loads, its pretty brutal. I've changed out the stock and backed down the handloads a little and its much more enjoyable now. With the brake, its like shooting a 3006. Dont use the brake much but nice to know its there if I want it.
