I mis-worded my first post. My accuracy seems to go out after the barrel gets dirty. I had about twenty rounds through it from the last couple trips out. Yesterday, I went to the range and it shot about an inch and a half group. Went home and cleaned it and when I went back out I shot four rounds through it and 2,3, and 4 were 1/2 MOA. This morning I went out and the above group was shots 5,6, and 7. So, I was wondering where anyone else shooting this caliber finds they need to scrub their gun?
The barrel is a #7 Lilja, 30 inch plus a brake, remington action, sendero stock, nightforce, etc. Thanks.
