Copper wire barrel brushes

[tstr]

Can copper wire brushes really damage a barrel? Is there something better that should be used?

I don't think that copper would hurt a bore. I think that brass is more "springy" and better suited for the job. Most bore brushes are brass.

I've been using phosphor bronze brushes forever with excellent results...

[addecus]

the steel wire that forms the spine of the brush can do damage. use brushes that have a brass spine and phosphor-bronze bristle.

I sort of wonder where these ideas come from. We drive copper or steel jacketed groove diameter bullets down a hardened steel barrel at two or three thousand feet per second at pressures that engrave the rifling into the bullet, and then worry about whether a few passes with a bronze brush is going to hurt the same barrel. Wow!
