The last group I measured out of my Browning when I was testing handloads was 0.62 inches. That was with Hornady 52 gr. BTHP match bullets and a case full of powder. The cases were showing pressure signs, but they sure did shoot good. I had a crosswind of 10-20 mph. On a still day with the Hornady V-Max molys, I can get groups of less than half that. I haven't put the calipers to them to check'em.
