Cut a 6mm creed barrel for my surgeon 591 recently and barely got it broken in before heading to Nebraska for a prs match. Loaded sone new 115 Dtac up and trued the bc out to 320. They had a side bet going at the zero range. I jumped straight from zero to the mile target. It was a 5 shot trial with a closest to center wins with no coaching from spotters. Went 4 for 5 (1 was just off view of the camera but was a hit) with closest just 3" off of center. Ended up beating out several magnums to win the side pot. Took home a nice rifle case for the win.
