[QUOTE="Mysticplayer, post: 33682, member: 8947"] Mine is the low tech method. Put a bullet into an empty case, blacken the bullet with a zippy marker, chamber by hand. Keep increasing bullet length until 2 or 3 land marks show up on the bullet (most barrels have 6 lands but they are never the same distance away). The marks will show up as a horizontal line in the ink. I repeat, this time chambering with the bolt. If there are no differences, then this is just on the lands. If you like a 'hard' seat, just keep increasing the bullet length until marks equal to the number of lands show up around the bullet. Only the ink is removed. The bullet is not jammed into the lands ie jacket scratched. I don't want to jam the bullet into the lands because if I extract the case, the bullet may stay allowing the powder to spill in the action and cause a nice mess. Jerry [/QUOTE]
