[QUOTE="Kiwi Greg, post: 1103193, member: 13456"] Yes but that is 338 LM brass not 300 or 338 NM brass. You are right the Norma/Nosler brass is softer than the Lapua brass in all the calibres I have compared them. Norma made the 338 NM to compete head to head with the 338 LM if the case design or brass was as soft as "normal" Norma brass it wouldn't have been close. A problem I see with the 338 NM is its lack of case taper & as the brass gets old it is unwilling to extract as easily as it should & is therefore junk even though the pockets are still in good shape, great primary extraction defiantly helps a lot with this. This is the problem I have with my Barrett 98B I re-barrelled years ago to 338 NM from 338 LM after I gave up on the crap factory barrel. I got a big Lilja barrel put into it at great expense, man does it shoot mint, but I can only run it at around 2750 fps with 300 Bergers, even then case life is less than desirable & it gets real old trying to pull the bolt back with the absence of primary extraction to help me. I converted my first 100 bits of old brass into 510 Whisper brass because it was way to good to throw out. Thankfully the 300 NM has a bit more case taper than its big brother :) [/QUOTE]
