Hi guys, I recently purchased a new custom Barrel from a well known barrel maker. I installed it and set out to determine where the lands are. Thats where the problems began. I can't even get the bolt to close on a factory round. Im running a 6mm creedmoore, RPR. This barrel is basically supposed to be a pre fit Barrel, plug and play with the exeption of its a straight barrel no contour. Depending on the bullet that im trying to use, its between .150 to .250 to short. Im trying to set it up for a few different bullets to test. 115 Dtac, 110 Atip, 110 SMK, or 105 through 108 various types. I read somewhere where Ruger initially had a similar problem. What's going on here?
