[QUOTE="Haagen Dazs, post: 632996, member: 42602"] Already read through the article and the discussion. That's waht put me on this track. As for bore life, if the 338 NM can get 2000 rounds, thats about double what a hot 7mm WSM should get, which is about 1000 from what I've read. Hard to say, but thanks for the different approch! 338 NM 82 gn = 1.42 gn/sq mm 7mm WSM 60 gn = 1.47 gn/sq mm [/QUOTE]
