I have reloaded since -75. Now I purchased into new rifle,the CZ 550 in .375HH cal.I want to use only one mark of brass from here on. What do you recommend,which works and lasts best in use.

I have shot a 375 H&H enough to have to rebarrel it. I have shot about every company's brass. If I has to choose, I'd say Winchester.
All of them are good, but Remington brass splits in only half the reloads of Winchester. Federal and Norma are good too, but Winchester is as good as any, and is the least expencive.

I use Winchester brass exclusively.

I have used RWS, Norma and Whichester. I have found that RWS and Norma lasted longer than Winchester . I have heard lots of good things about Hornady.
