So I was ordering other crap from brownells, and totally got upsold to make us of shipping on these Jags.
They were kinda expensive, but I liked the theory.
I tried the .45 one after a match. It was impressive how much stuff these things drag out, since they deform into the lands. You still have to brush when it gets heavy, but compared to my regular jags it took fewer passes to get a sparkling clean bore.
They say on the package that you can stick 0000 steel wool or brass wool on the jags to help get out stuck fouling, i've never heard of this, but it might be worth a try. That level of wool would be fine on a bore.
One thing, they are a bear to push down the pipe. I was using cotton patches (thicker t-shirt feeling ones I cut from shotgun) and they were hard. You would probably want to use the die cut ones that are thin and silky looking.
