I'd buy 500-1000 brass and your set for life.It's still available here in Canada.Too bad metric calibers aren't more accepted in North America ie 5mm rimfire etc...........The 7x57 and lately the 6.5X55 are still out there doing what they do best slaying large game with minimal recoil......Harold *I use a FN Safari in a .308 Norma Mag but brass can be fabricated from 300 H+H or .338 in a pinch
