[QUOTE="ODAVID, post: 1272703, member: 13431"] First off I feel the main factor is how you measure the distance to the lands. Assuming you are doing like I am then Using 168 berger hunting bullets seated .060 off lands with a comparator COAL LENGTH tightest group was 4.092 1/2" groups at 200 yds. second tightset group was 4.086. 3rd tightes group 4.094. I was told Start at 4.088 go higher or lower in .002 intervals. Works for me as barrel wears I will increase length of COAL to try to get what life I can from barrel until being replaced. IF THIS MAKES NO SENSE TO YOU I COULD ANSWER SPECIFICS IN PM> BUT NOT GENERAL QUESTIONS. PASS THE HELP ALONG TO OTHERS IS ALL I ASK> ODAVID [/QUOTE]
