Okay fellas, I've been wandering the halls here, and have found alot of great information, and if I ever find a cure for something that ya'll haven't already remedied, I'll proudly post it. BUT, for now I need some of your thoughts.
I have an Interarms Rossi M92, stainless, .357 that arrived in as new condition, without normal wear indicators. Since, it has been well broken in and tweaked as is commonly necessary with these rifles. Recently, I added a dovetail front sight, eliminating the barrel banded front, and added a Skinner Low Pro. Front dovetail is level and square to the receiver and Low Pro is centered and "plumb" to the bolt and receiver. Previously the front band had to be turned to the right as much as mag tube alignment and band pin would allow and rear drifted a bit to the left to center POI. Forgeting (seems to happen more frequently lately) the mathematical reality that as sight radius lengthens, the amount of movement necessary to correct windage increases, I believed all would be well. Many "well"s later (and quite a few "well h_ll"s for good measure) I find that the front sight has to be nearly off the right side of the barrel to get centered POI at 50 yards. I've tried different powders, charges, boolits, O.A.L., etc. resulting in varying elevations and group sizes, but not much effect on windage. I've loosened and even removed barrel bands and forend. Different rests and holds don't offer relief. Barrel is straight and pristine, without fouling or leading. Groups are great,(with the right load) just too far to right of POA. The crown appears uniform, but I don't have tools to measure any discrepancy. I'll be taking it to the local gunsmith this week for his evaluation but what thinketh ye? I have "regulated" shotguns by careful muzzle alteration, but can a rifle be recrowned or the crown lapped to correct windage? What possible cause and cure is there? Comments? Ideas? Derogatory remarks?
