I bought one in 30-30 after a friend talked me into it. Well I was very happy with it shooting lead bullets, but never impressed with jacketed loads. Jacketed loads averaged about 2-3 inches at 100 yards. Tried different loads and once in a while got a good group, but could not repeat it. I recrowned the barrel, beded the forend and changed scopes. Nothing seemed to help and started thinking I was doing something wrong. As a last resort, I decided to slug the barrel. Slugging it gave insight to what might be the problem. The bore measured .308 at the chamber end and tapered out to .3095 at the muzzle. Well this is not good and wonder if this is a common problem with 30cal NEF barrels. I wonder if this was a fluke or a common manufacturing problem with their barrels. It could be that someone forgot to measure the bore before attaching the lug and chambering. I think I will try calling NEF and see what kind of deal if any they will make for me on a new barrel. I quess if they at least promise to have the bore taper in the right direction I'll buy a new one.
