[QUOTE="GCF, post: 403968, member: 25668"] New guy here. What I just started doing to determine COL to Lands, is first teflon tape (single layer w/ slight overlap) from the base up, the bullet in question. Next, I hand seat it in a clean / fired / unsized case. Slowly, fully chamber the round w/ the bolt, & then slowly extract the case. If done right, the bullet will be lightly stuck in the lands - by the teflon tape, & can be gently tapped out w/ a cleaning rod. A clean "shoulder" should be formed in the teflon tape, that when re-inserted into the fired case neck - & measured, will show you "exactly" how deep the bullet was seated when "on the lands". Pretty easy to figure various seating depths for desired distance off lands, from that point. When I figured this method out (blind hog finds acorn), is seemed overly simplistic. Seems to work though... Kinda' wonder why I never though of it before... ;-] Give it a try, & let me know what you think. Gary [/QUOTE]
