[QUOTE="woods, post: 296347, member: 6042"] Like AJ said, if you want to be off the lands then you need to thread your seater in further to push the bullet deeper in the case. You are also going to push the bullet a significant distance into the lands if you are seating the bullet in a new case and chambering it to let the bolt push the bullet further in. A new case usually has somewhere around .003" bullet grip which holds the bullet well and the bullet will resist movement in the neck and be pushed into the lands. Also the lands will grab hold of the bullet and when you extract the case there is the very real possibility of the bullet moving back out of the case neck some distance before it releases from the lands. Easiest way to measure to the lands is to get the Hornady OAL tool and learn to use it. Other ways include 1. Cutting a slot in the neck to make the bullet movement easier as you chamber it 2. Blackening the bullet to gauge when you are no longer hitting the lands and if the bullet is moving in the case neck 3. Cleaning rod or dowel down the muzzle to the bolt face and then to the tip of a lightly seated bullet, marking the rod and measuring between the 2 Probably others I have left out. Get the Hornady and you can get lots of help here and elsewhere to learn to use it because many use it. [/QUOTE]
