Was hoping to shoot some today, but it started raining. Be weekend after next before I can get them chronoed.

Will updated results.
 
I found them to be very accurate. I settled on 10.6 grains of TrailBoss in Winchester cases, Federal 210M primers. 2.800" COAL. The only thing I found odd is that the first shot or two are consistently ~40 fps faster than later shots in a string. Could just be my rifle. It's a JP LRP-07 with ThunderBeast can. Adjustable gas block with the gas shut off.
