[QUOTE="MCC335, post: 2880363, member: 127401"] Hi everyone! I have been working up a load for a custom 300 PRC with a 24” barrel. This load shot 0.3 MOA at 100 yards several times, but intermittently opens up to about 1 MOA. ALL components I am currently using are from the same lots. Lapua Brass Federal 215 77.7gr H1000 Berger 215 COAL 3.747” (-0.020 from jam, +0.006 IL) 2844fps (ES 14-21 with multiple 3-shot groups) RCBS FL bush die with 0.335 SAC bush 0.306 Mandrel I have 2 questions that I need help with, both of which I think may be adding to my inconsistencies: 1. Is enough bearing surface of my bullet in the neck? At this COAL = 0.180” bearing in neck) 2. Enough neck tension? What bushing are you guys using in the 300 PRC Lapua brass? My loaded rounds are 0.3375 but my 0.306 mandrel is very loose after 0.335 SAC bushing. Thank you, Gino [/QUOTE]
