I gave this a nudge on the weekend, unfortunately only had a handful of magnum primers so just loaded up what i could to see what would happen. Loaded 6 rounds at 3.340 with 74gr of 2217 and another 6 at 3.614 (15 thou off lands) with 74gr of 2217. The 2 groups of 3 at 3.340 were .7 and .6 moa which is pretty normal for this rifle if i do my part. The 2 groups at 3.614 were right on 1 moa, first one a tick over. Untill i can get my hands on some large magnum primers i wont be able to take it any further but seems it certainly prefers the std COAL compared to 15 thou off lands.
