I originally cast these boolits from the Lee C312-155-2R mold for my AK but they dropped too small for the bore. After striking out with another mold for 308 I found these 155s laying around and decided to give them a try.
I sized them to .311 and loaded them with IMR4227 and some with SR7625 just because those were the only two suitable powders I have. Accuracy with 4227 was pretty bad and stepping up the load didn't seem to help, but the loads with SR7625 really impressed me. This rifle regularly shoots 1/2" - 3/4" groups with jacketed bullets but the most I was expecting out of cast was around 1".
What really amazes me is there's such a huge weight variance with these cast boolits. I didn't even sort them for weight, just sized, lubed and loaded them. Nor did I use any dacron or any filler. Just 12gr of SR7625 sloshing around in a 308 case. And yet look how they shot. Now if I can just get the same results out of a proper hunting boolit moving at a more respectable speed.
