[QUOTE="Don Rackley, post: 3013575, member: 123332"] Just curious if anyone has seen velocity differences from what the Hodgdon website shows. I loaded up some new ADG brass for my 7PRC with H4831SC. I started at 62.1g with 162gr ELD-M bullets and Federal LRMag primers and shot them from a Proof 24" new barrel. The website shows 64.2gr of H4831 should yield 3,018fps. I got an average of 2,906 fps from 5 shots off my MagnetoSpeed chronograph with no pressure signs or hard bolt lift. I did get some 0.50MOA groups at 63gr and 2,860 fps, but thought I would get more velocity. I'm going to keep going carefully on charge weights to check velocity and watch for pressure. I would like to try some H1000, but an 8lb keg is very hard to get........ [/QUOTE]
