Hi fellas. I'm new here but need some advice on a rifle accuracy problem.
The rifle is a Rossi 92 that I purchased to recondition. It had a Ramline stock and had been abused. I did a lot of repair and cosmetic rebuild and stocked it with some curly walnut. Perhaps I can post pics eventually.
Looks nice now. Problem is it won't shoot for ****. I only want it to shoot reasonably out to 100 yards and would use it as a brush gun for deer. As is it groups factory jacketed bullets about 12 inches at 50 yards. I can do much better with a S&W 29 offhand. My brother (another amateur smith) upset a couple of slugs near the breach and the muzzle and then measured them. The gun has extremely shallow rifling and the bore measures 0.4316 in the grooves near the breech and 0.4320 near the muzzle. Measures about 0.428 across the lands. It looks like normal 0.429 lead will be loose in the bore and may actually have blowby.
Questions: Will I see better bullet stabilization and accuracy with a slug measuring 0.432 (groove diameter)?
If so, is there anyone out there with a few boolits near this size that I could reload and try to see if that is the solution? I'd like to test the solution before committing to a special mold.
Help?
