[QUOTE="Rhovee, post: 1681289, member: 101820"] I have both 300 Norma Lapua brass and 338 Norma Peterson brass. Both are very tough brass. I went way over pressure (65k) and neither had loose primer pockets or ejector marks. I knew from the speeds that I was hot. Both Peterson and Lapua brass is shorter on headspace than Norma. I had the gunsmith hold both chambers back for minimal body growth with fire forming. It can be a big deal for case head separation and longevity of brass. Holding the typical Improved chamber .004 short isn’t going to cut it with both these brands. [/QUOTE]
