[QUOTE="VinceMule, post: 3018652, member: 122164"] Sorry, I never found that the light bullets like big jumps they like to be .003-.020 off the lands for sub 1/4" groups in 222, 22 PPC, 223 AI, 223 Match, 22/250 & AI. By the time I was jumping them .060, accuracy could never be attained again. New barrels with fresh cut ramps on the leade angle help, but in 600 rounds, all the fresh is gone. A flat base bullet can help with the jumping when the barrel is new. P. dog shooters firing 600-1000 rounds a day on a single barrel figure stuff out pretty quickly(minute of p. dog head at 300).
