I have two ar15's, one with a pistol length gas system and one with a rifle length and haven't been able to find a powder to make both work reliably with one single load until today. H4895 and Varget were too slow for the pistol and IMR4198 was too fast for the rifle. I stumbled upon a pound of BLC-2 and loaded up about 50 out of my 10k 62gr bulk bullet buy. Bam, both functioned with 100% reliability. Now to get busy and fill up a few thousand cases!
