rifeling

samsonj · March 21, 2000, 10:42 AM

I actually have two questions, I hope they are not dumb.
First, with the future requriement of gun manufacturers to keep a record of the rifeling marks on a round from any gun they produce and sell, is their any way one can change those markings to in essence mask the ID of the gun?
My second question is about a single action revolver I own. The gun is a 45 colt long copy, the cylender is scared where the cylender is turned. What should I do? Nothing? How would I find out about replacement parts? Thanks for the help.

Any barrel offers two distinct pieces of information; 1) the number and depth of lands and grooves, and 2) any striations in the steel which will be unique to that barrel.

# 1 identifies only the manufacturer. The barrel is one of many thousands, even millions.

#2 is indeed unique. If one does some "really bad thing" and wants so desparately to keep that particular barrel, the striations must be changed. Cleaning with a fine polishing compound MIGHT be sufficient. A slightly coarser compound SHOULD be sufficient.

In the event of an expected Really Bad Thing, the use of a semi-auto is NOT recommended.

On the Colt copy, the scoring sounds like the normal thing that occurs with use. Unless it affects the lock-up notches in the cylinder, ignore it.
