I've also used the pad from Big .45 and have nothing but praise. I've tried similar items from Brownell's, the Outer's Rust Ridder, and the item offered by Midway. Hands down the Big 45 item wins as it "cuts" better and lasts longer. In my remote part of the world however Bronze wool is easier to find. A review of the Big 45 offering can be viewed here:
