[QUOTE="DanGuy48, post: 1289640, member: 48538"] I read the article by Winker on this site but still wanted to ask about this. So, I'm an RSO at a local range, indoor, 25 yds. max. We are rated though for anything up to, and including, .50 BMG. A couple came in with a brand new Savage 112 in .338 LM, Vortex 4-12 (IIRC) to get it sighted in initially. They used a bore site and aligned the crosshairs to the bore and fired at 12 yards. The shot was about 4 inches low and right. He inserted the borelight again, scope and laser still matched exactly. Fired again and same thing. I asked if I could take a shot. We inserted bore light and again cross hair and light seemed perfectly aligned. I ran the target out to 25 yards and fired. Low and right by about 6-7". At this point we decided something is definitely wrong. They bought the rifle at Cabellas and did mention that the person there had the muzzle brake off fiddling with something for some reason. My initial suspicions are: - muzzle brake is contacting bullet - barrel crown is damaged - barrel is not threaded true to action. Winker also mentioned bent barrels but I really wouldn't expect that on this rifle. I told this couple I'd ask about this here to see if I am missing something, or if they need to send this one back. So, does anyone else have any ideas? Should the rifle be sent back? Am I just completely missing something simple? [/QUOTE]
