[QUOTE="Black Tail Hunter, post: 1345613, member: 59604"] I've found that, when your lands are sharp on a newly chambered barrel, the bullet will be engraved a few thousandths by the lands when measuring for the first time. Thus a longer measurement. After a few rounds the sharp edges are rounded enough that the bullet will have a positive stop for subsequent measurements. Ive experienced this on a few different barrels. Nothing to worry about, just trust your measurements you're getting now from now on Very interesting, I would have never thought that. My rifle wasn't new but was low round count, could have played into the scenario. I will clean thoroughly and re measure. [/QUOTE]
