Loaded some of these up and shot them today. Onlyn did three powder charges in half grain increments. Stock Kimber Monatana 300WM, and it was the 190gr 30cal version.

Two charges shot about 2MOA, whilst one shot .7MOA and was "2 in 1 out" , similar to the groups shot by the OP. My buddy ho gave me them to try had the same issue with the powder charges, and im curious if anyone else has seen this?

Obviously different powder charges will shoot differently, but ive never seen such a big differencd in group size. Now all ive left to do is tinker with my one good load and see if it can be improved.
