[QUOTE="GoneHuntingOutfitter, post: 840396, member: 70556"] A little more information on the issue! He started the break in process with some Hornody Factory Ammo in a 190 Grain bullet, showing at 2920 FPS on the box. This ammo shot through the Rifle fine and never had one stick. The brass the Factory ammo was fired in shows .040 under Max Case Length. The new brass is at .010 of Max Case Length and every one has stuck no matter what load we put in it. IMR 4350 65 grains (light load) , H-1000 79 grains (middle type load), 7828 ssc 75 grains (middle type load), all with 180 grain accubond. We then resized a fire formed factory brass and loaded it with the 7828 ssc. Again this brass was still no where near MCL. Fired the shot and it stuck. Still no bolt lift pressure, but the case takes some work to get started backward. The place it sticks is .085 in front of belt and it leaves scratching for another .100 as we extract the brass. This mark is all the way around the brass where it sticks. Can't see in the chamber well enough to see if there is just a rough area. Still no signs of pressure on the back of case or flattening of primer. Fired cases are not stretching excessively either. Called Remington today and it sounded like maybe they have seen this before and think the Chamber just needs a good polishing. Will give it a try and see. Thanks to all that have responded with Ideas! [/QUOTE]
