Thanks guys, I did & it seems that leaving the barrel w/ 1 shot through it (fouled) doesn't make too much of a difference. Once I allow the gun to get cold again, it hits high again. I'm pretty sure the barrel is defective. anyways F! Knight. When Gary Knight owned it, his employees would email or call back.
Also wanted to ask CVA & T/C shooters what bullets & propellants or "loads" they like, esp. for Elk. Thanks again, Jim
