[QUOTE="Jester896, post: 1465508, member: 41793"] I have a fondness for 6.5 caliber. I have a LR target gun in .260, a medium range hunting rifle in .260. I wanted something for a little longer range so I had a 6.5WSM built on a 700 L/A I had. There were 3 of these built with the other 2 being S/A. Both of those rifles use the same load data and perform very close to the same. Mine however will not. I can drop it a whole gr or more (IMR7828) and there is no change. I can slow it down 200 fps and no significant change. Primer smashed and bolt very hard to lift. Normally I find copper fouling at the throat and muzzle of my other two rifles and minimal I believe. This one when I look with the borescope there isn't much at the throat or muzzle but the rest is heavily copper fouled. We have taken it apart 3 times to check it. Resurfaced the action lugs and action face, checked counter bore depth, set the barrel back and re-cut the chamber. Don't know what else to try. Almost think it is a barrel issue. [/QUOTE]
