[QUOTE="25WSM, post: 1777576, member: 38048"] I have not had brass issues with the Norma in my wby. Yes the brass is on the softer side but hasn't hurt performance to me. I don't reload to make the fastest bullet ever. I don't like to leave too much on the table either. Have a goal in mind and stay there. If you want 3600 with a 100 grain bullet it will do it. I'm happy with that speed. If I want 3650 it can normally get there. If I want to get 37 to 3800 I will build something with more capacity. Lots of guys say they get 3800 with a 100 gn. I won't ruin brass to get more. The norma brass works. I don't know why but I think the 257wby I'd one of the most accurate rounds I've ever shot. And boy does it drop deer. Barrel life on the 257, 270,and 7mm case seems to be very good to me. You can expect 1200, however I can sqeeze 2000 rounds from a barrel. I shoot the first 750 and do a 2 turn set back. I get another good 750 and these 1500 shoot real good. Then when the erosion tells me I cut about a half inch off and rechamber over again. Barrel at this point is 3/4 shorter with all the trims but still shoot lights out. I have given these barrels to customers and veterans and no one has ever complained. You will love this cartridge.
