Re: cutting down shotgun barrels
Funny you should mention that. I currently have a Winchester 1300. Years of youth and abuse have made me cringe whenever I pull a choke tube out of the barrel and see the corrosion on the threads. I'm starting to think this may not be safe (either that or it's my brain rationalizing the need to do this). So, I'm purchasing a new barrel for hunting, a 26" gloss barrel threaded for Win-Choke (ah yes, I've since learned the joys of choke tube grease) and when I go to a friends parents house for the weekend in August, I'm going to have the original one cut down to 20" or so. My friends dad is a machinist, he'll cut it with the bandsaw and then smooth the crown. Add a set of fiber-optic rifle sights to the rib and presto! a new home defense barrel.
It's all fun and games, til someone shoots your bobber!
