I use the Bore Tech products and I'm very happy with the results. Just this week I cleaned my .22 magnum trainer after shooting 200 rounds. Now, .22 Mag. has the same cleaning requirements as centerfire rifles because it uses copper jacketed bullets at 2200 FPS.
In order to get the copper out of the barrel you have to clean out the carbon first. I use Bore Tech Carbon Remover -15- passes with a nylon brush then let it sit for 5-10 minutes. That's followed by wet patches until they come out clean then a couple of dry patches.
While the Carbon Remover is sitting, I use a short rod with a .243/6mm nylon brush inserted into the barrel throat about a quarter of an inch or so and twist it about 15 times to remove the carbon ring.
I then use the Copper Remover, again, as per the instructions on the bottle. Five or six passes with nylon brush, sit 5-10 minutes, then wet patches, etc.
Finally, one pass with a very lightly oiled mop, then another pass with the oil removed from the mop and I'm done.
Below is a picture following the copper removing process with the patches I used. The sequence is left right with the top row being the wet patches and the bottom the dry ones.
Look at the patches and the mop. Not a hint of carbon anywhere. The Carbon Remover took care of that. The Copper Remover obviously works great as well
