I hit upon a great idea (at least I think so
) while cleaning my rifle this week.
Have you ever had the jag (I use tipton nickel plated) bang on the crown while pulling the rod back? Well I came up with a cheap easy fix.
Take a piece of Heat Shrink Tubing, put in on the rod over the metal to fiberglass interface if you have one (Tipton Rod) and shring it down with a lighter. It increases the diameter of the rod just enough to make the jag miss the crown but no so much as to scour the chemicals out of the barrel.
I use automotive grade heat shink tubing as this is chemical resistant.
