You might have to trim the neck a little with the 375 Win brass, but it is a lot stronger than the 30-30 Win brass. I bought the 375 Win brass for the 30-30Al and the 7-30 Waters

I have been told that if you tell the maker of the barrel that you are going to use 375 Win brass they will make it were you don’t have to do anything to the brass. I am also under the impression that you don’t have to fireform the 375 Win brass
