20” OMR barrel – suppressed
Peterson brass
Federal 210M primers
40.0 gr H4350
88gr ELD-M
2.600” COAL
Started load development at 40.0 gr since I’ve seen some guys pushing up to 41.5+. My first three shots gave tighter, but not awful bolt lift, and light ejector marks on the brass. Speeds were insane:
3302
3318
3307
Group was within half an inch. Safe to say I’m on the cutting edge and have officially found my max
Backing it off 0.3 grains and dialing it in from there. where are yall landing for powder charge with the 88’s and H4350?
Even factory 80’s out my 20” barrel were pushing 3250. Hoping after backing off on charge for the 88’s I’ll still be around 3250.
