I'm thinking about casting supersonic loads for my 300 blackout. I'm looking at a lee 113 gr fn 30 cal. mold. Just trying to find out if anyone has tried this load and if so what load recipe did they use and any info they may have. I will be shooting these out of a custom built ar, I don't care about leading issues or plugged gas tubes cause I constantly maintain my guns probably more than I should. Im really just interested in how well they work and if there's any feeding issues. Thanks Sean
