[QUOTE="milanuk, post: 23589, member: 376"] Jerry, I'm trying to wrack my brain for anything and everything that I did to the gun around the time it started acting a little weird. I know I pulled the action out of the stock to look at something, and I'm not sure how tight I got the screws when I put them back (no torque wrench, so I settled for 'snug'). I went from Butch's/JB BorePast to Sweet's/JB to Hoppes #9/Jb to Hoppes #9/Sweets back to Butch's/JB. I had changed scopes from an SS10x42 in Leupold QRW rings to a Weaver V16 in Burris Signature rings. Had a period where the front ring was far enough forward that it was actually on the front bell about 1/16th to 1/8th inch, and was acting haywire. Got that straightened out, and the gun was shooting fine (once it was fouled). I should mention that the gun went from shooting consistent btwn cleanings, but needing cleaning every 20-25rds, to needing up to 10 shots to settle in, but then shooting indefinitely (up to 80rds, haven't pushed it more) w/ no appreciable drop-off in accuracy. The load I was using was a 175gr SMK over 45.0 gr of Varget, Winchester cases, CCI BR2 primer. Come to think of it, most of the weird zero problems have been since I ran out of 175 SMKs. Hmmm.... I went to some custom 185gr VLDs, but I think they are too heavy for the .308 for longer ranges, so I've been testing some 155gr bullets. J4's for the moment, as that's what they have handy here. I twisted their arm, and there should be some A-Maxes on the way. I've been playing w/ Viht N-140 lately, as it shot some really tiny groups w/ 155gr J4s. Meters nicer than Varget too. Tad more expensive, and from what I've heard, not as temperature stable, so I may end up back w/ Varget (sight, could be worse, could be 4064 or something else similarly heinous). As far as the copper fouling, I'd have to say not as much as initially. But that's judging by the muzzle end. How do you see the copper in the throat w/o a borescope?
