[QUOTE="MT6.5PRC, post: 2271771, member: 119698"] I've been developing some loads using H4831SC w/ CCI 200 behind 140gr GMX (only copper bullet my rifle likes) and 140gr ELDM. Found a good node at 54.0 grains, it was grouping around .6 MOA at 200 yards, clocking around 3,000fps in a 24" barrel. Didn't check groups farther out, but was consistently ringing 10" steel at 650 yards. Then I cracked a new bottle, loaded five rounds w/ 54 grains again, and the first round hit 3,150fps, blew the primer and had the worst brass flow I've ever seen. Left the rest of those rounds alone. I dropped down to 50 grains, and now it's consistently clocking 3025 at 50 grains. I think the wrong powder went in the bottle or something is off with the batch I got. Anyone else seen velocities like that from any H4831SC bought in the past couple years? I got that bottle right before the shelves emptied of powder. [/QUOTE]
