[QUOTE="JJMoody, post: 1445655, member: 89869"] Just traded into a 300 Lapua. It came with some loaded rounds, 8 total shots fired 10 twist on a 700 action. Looking at the once fired Peterson brass, all the primers are cratered. The loads were around 93-94 grains of retumbo under 208-215 ish class bullets. It seems this would be a lighter load, on par with what I've seen from RUM loads. I also noticed that primers on loaded rounds were seated proud, sticking out past the face of the rim. I have an ample supply of 208 ELDM/AMAX 212 ELDX 200 and 220 SMKs( barrel twist may not be right for these) 225 ELDM some 215 hybrids. Really want to try 181 Hammers though. I have a big jug of H1000 but may give Retumbo and RL26 a look. And just because I like kinda simple, I'd like to keep powder the same in this and my 28 Nosler. Questions: 1)Could primer seating depth be affecting pressure signs earlier than should be? (Cratering?) 2) where should load work up begin in a 300 Lapua? Not much info out there. I have looked at accurate shooters article 3) today's best powders? Must be temp stable. 4) how much advantage over the RUM? Not looking for other cartridge options, just some help on this guy. Thanks [/QUOTE]
