Idk if this should go in the gunsmith thread or not but it’s kind of a hybrid question.i have a service grade CMP garand that using Winchester 150 grain ball ammo shot about a 4” group at 50 yards. Well the crown is in really bad shape and is obviously a big part of the horrible accuracy coupled with me shooting iron sights but I was shooting off of sand bags from a sitting position. I’ve been throwing around in my head the idea of re-barreling it instead of renting a crowning tool. Renting the crowing tool would be a little less than $50 and renting all the stuff and buying the barrel would cost me about $300.
The real question is for cast bullets is it worth it? The current barrel has stron rifling and the throat is already tapered from previous shooting. The diameter is .3094” from slugging and sizing to .310 gave the best of what accuracy there was. If I get a new barrel I figure I’ll probably end up having to send it off to a fellow on here to have the throat smoothed out for cast bullets. Am I completely wrong here or what? I just don’t want to get a fresh barrel with a throat that is going to shave lead.
