Hi everyone! Been a few years since I have been on here. Been moving and working a ton. Anyways I had a chance to pickup a montana rifle company x2 rifle in the 26 nosler. I have a farrell 20 moa base leupold rings and a vortex hst scope mounted on it. I was told it was a used rifle when i purchased it. But there was no marks on the follower or the bolt face that indicated it had been shot. So I scrubbed it with gunslick foam cleaner before taking it out. Well I bought a box of nosler 129 grain AccuBond bullets to put through it. Set up the chronograph and shot. Here is the interesting part. The first bullet started at 3215 fps. I let the barrel cool at least 3 mins between shots. 2nd shot was 3225 fps. I proceeded to shoot with letting the barrel cool between shots and the velocity climbed on each shot. By shot 6 the velocity was at 3365 fps. Then the velocity started to fall off back down to 3240 fps by shot 12. I have never seen a rifle do that before. I couldn't get the gun to group better than 4 to 5 inches at 100 yards. I stopped shooting and took the gun home and adjusted to trigger to a nice 3 lbs, scrubbed the barrel with bore paste. Took the scope, base off the rifle and cleaned everything to a t. Put it all back together and torqued everything to specs and then took it back out. Rifle still would not group better than about 4 inches at 100 yards. Last 3 shots went into a straight horizontal line about 2.5 inches with no vertical variance. What are your thoughts? Ammo related, bedding?
