[QUOTE="jdmecomber, post: 1558871, member: 94549"] Well 112 rounds in and it appears the barrel has settled. We settled on a node in the 2940's. It has produced three groups now with 7,12 and 15 ES. This gun with Reloader 26 hasn't produced a group over .75 moa with 3.5 grains of powder around 190 fps in total spread. I think once I get prone these groups will get better. We have multiple groups under .20 moa. We tried some other powders around the same node of 2940 and it was a failure. The other powders were very unstable in the same node. H1000 and Retumbo were used. Imr 7828 SSC had around an moa in group size and about a 15 ES with new brass. I think this could really improve with fireformed brass and some lands movement, but this is a hunting rifle. The customer should be happy. [/QUOTE]
