I’ve run the lee 230 with PC and it had a similar POI as my 150 FMJ loads

I also use the 230gr Lee mold, beagled to drop at .310, single coat of HF powder coat, then sized to .309 and loaded subsonic over 10.8gr of 1680. COAL of 2.210. I run them suppressed (Silencerco Hybrid) both semi auto and full auto through an 8” Noveske barrel with an adjustable gas block. They cycle and LRBHO without any issues so far. I’ve been through about 300 of them in the last month. I’m not shooting for extreme accuracy, but it hits soda cans all day long at 50 yards through my Aimpoint while semi-auto. Chrono has them at about 1025 in 55 degree weather. There are better molds out there, for sure, but for a good plinking round dropped from a cheap mold, I have no complaints.

Not a problem. If you have any issues with your sub loads or setting up that gun to shoot and cycle them, just shoot me a PM.
