I've been working on some Barnes loads. A guy at the range said that his loads worked best when the triple X was loaded .050-.070 from the lands. Mine were much closer and perhaps accounted for the larger groups. The surprie for the day was the MRX.
140gr MRX with 62gr of IMR 4831 federal 215primer and COAL 3.260. It was basically two holes but I ripped it a little in my hurry to get it off the target board.
Couldn't have done it without the help from this site. Thanks guys.
