Quote: My question is what OAL I should be using. I usually load for grendel at 2.26 or close to it. However, the Barnes data for this bullet indicates and OAL of 2.235. My recollection is that the copper bullets often shoot better with some jump. I imagine some of you have loaded for this bullet. Any advice?
If it were me, Id load them to what the Barnes data says and shoot them. In both guns. If it doesnt work in one or the other, then start experimenting with OAL. Generally speaking, loading longer with the same powder charge usually means, less case volume, less pressure and slower speeds. All things being equal, copper monolithic projectiles expand better at higher speeds. YMMV!
