In another [which I can't find] some of us were talking about the new Mossberg 100 ATR riffles. I bought 2, 1 for each of my son's for Christmas. I'm happy to say with handloads that at 100 yards we now have a 3 shot group all touching. The load is 54gr. IMR 4350, 130gr. Serria bullets CCI large riffle primers in a Winchester case. The are set at factory length and we will tune them in by moving they closer to the lands on the next round.
