Like the title says, I got this magnificent MP mold, made 2400 of the no lube groove no gas check model with clip on wheel weights, and hoped I'd find a happy AR load. Well, I simply didnt. For fun, I loaded some J word 55gr, and got sub MOA groups, so I know how to make a decent load, but after loading PC'd cast for 10 or so different rifle calibers at full power jacketed data, I'm quite perplexed. My groups were hilariously bad, I have yet to get worse than 3.5moa in other full power calibers, but at 50 yards, this group(??? hahaha) was unmeasurable it was so large. I was driving these pills at 2550-2700fps, and my first reaction is to say im driving waaaaay too fast. My first inclination is to reduce my load to 1800-2000fps, which I assume may have positive results. Anyone have any luck with this projectile? I'd sure love to hear good news, but if not, I'll just heavily reduce.
