Welcome to the fire!
Nosler lists a max of 52 gr of BG w/ their 120 gr NBT using a Nosler case & WLR primer with 50 as an accuracy load. The 2 rifles I load for (using LC 7.62 NATO cases resized & sparked by WLRMs) like 49 gr for accuracy.
Every rifle is an entity unto itself so work your way up but this sure seems like a winning combo as it's heavily favored here on the fire and elsewhere.
