Problem with mine...
Years ago I bought a cheap imitation made by Hoppe's. I used it for .45 and .44, and I never had a problem with it. I recently bought a model 64-6 off Gunbroker for a decent price, and I don't know if it's the ECM barrel or what, but this revolver has some of the worst barrel leading I've ever seen. I wanted to buy a new .357/.38 caliber rubber jag from Hoppe's, but these don't seem to be made anymore. So I splurged and got a Lewis Lead Remover kit since it wasn't that much more expensive than just the jag alone.
The problem is that the jag just punches through the screen every single time. It's the same for the barrel or the chambers; the jag just punches through the screen without even coming close to pulling it through the bore. I've followed the directions, and I've tried every possible way of forming the screen, setting up the jag, and holding my tongue just right; nothing seems to work. I notice on the old Hoppe's jags, the shoulders are rounded while the new Lewis jag has a sharp shoulder. Am I missing something?
