Thanks for all the great ideas on the "usefull info from factory loads" thread, now that I have done some more shooting, the factory loads will not shoot well either. I though it would be great to have a checklist of things that loosen up, wear out, or any other factors that would make a rifle no longer shoot well. My rifle is a browning a-bolt 300wsm. It has seen less than 100 rounds. It once shot .750" to 1" groups at 100 yards very often. Recently I have shot several groups averaging 2.25" I checked scope rings and mounts, everything seems to be tight, as well as the stock. One thing I suspect is that I spent much more time and effort getting copper fouling out of the barrell before this all started. It was something I knew about vaguely, but learned about since using this site. I tried several methods and got slow but steady progress with sweets. It took aprox. 30 repetitions of the process described on the bottle. This was done after about 60 rounds fired through the rifle since new. I cleaned from the action toward the muzzle with a one piece coated rod and bore guide, however the bore guide was somewhat soft plastic. When I bought the rifle several years ago, I also had "vague" knowlege of barell break-in. I "cleaned" the rifle several times in the first box of ammo with the bore-snake rope type cleaner, and no solvent. I imagine it was better than nothing, but highly double the barell was actually clean. Any ideas? Has a checklist ever been made on this subject?
