[QUOTE="Ckleeves, post: 1508477, member: 83259"] Just curious if anybody else has ever ran into this before. I loaded up some virgin 300 WM ADG brass the other day with h-1000 and 215 Berger’s. My normal load is 76.5 grains in Winchester brass and 78 grn in Norma or nosler. I started low like I always do in unknown brass, 71.5 grn and fired 3. Velocity was higher then I expected but still low compared to my usual node. Primers were flattened but zero hard bolt lift or case head marks. I continued up in charge weight with the same results. Effortless bolt lift and not even the faintest of head marks but pretty darn flat primers. I have never flattened primers like this before even in overpressure loads that made the bolt sticky and made swipes on heads. Thoughts? [/QUOTE]
