Casting the RCBS 140 Grain Sil and using 2400 powder, these are the first trial groups @100 yards. Groups 1&2 with 15.5 gr 2400 and no filler, Groups 3&4 with
15.5 gr 2400 and 1 grain dacron filler. Group 1 1.505 (8 in .665), Group 2 1.427, Group3 1.617 and Group 4 1.425. I think with a little tweaking this will do ok. 1 in 9 twist 6 Groove.
