I'm building a 300 Blackout with a Adams Arms piston conversion. Has anybody worked up a functioning hand load for a piston conversion? I'm using a Daniel Defense 16" 1 in 8" barrel, and a H3 buffer, a Palmetto State armory lower. If anyone has worked up some hand loads that cycle the action well, please pass on the info. Thank you, Roger

300 Blackout, Adams piston conversion. Anyone with reload data for 125 TNT , IMR 4227 starting load to get cycling zeroed in.
