I tried one for a while. Universal one, more of a pain than anything.
I just clean it and don't worry about it. A slow rod is not going to wear it like a bullet going 2800 fps. Or even given it could, how many rod runs at under 1 fps does it equal a bullet at 2800 fps?
My take continues to be that while someone can wreck a bore with a steel rod from the front with endless cleaning, its an urban legend.
You look at a barrel with a bore scopes and a rough one shoots well and a clean one shoots poorly.
How can you tell if you are not shooting that barrel?
Ie. how does a gunsmith come to the conclusion its does not shoot well?
Owner can't shoot? Bore is shot out and nothing to do with cleaning?
