I can usually shoot 1" groups at 200 with 80g SMK in PacNor 8t 223AI and 90g Berger BT in 7.5t PacNor 6BR using Varget in both. When I had 107SMK's, with N150, again 1" groups or better. For the life of me, can't get these Nsoler RDF's to shoot better than 2" at 200yd. I've tried Varget and N150 and can't say I've gotten a good load testing over 140 rounds of various loads and seating depths. Whidden FL sizer, Wilson chamber seater. Primers are BR4.
