Anyone own a .177 rifle or BB/ pellet bore bristle/ cleaning brush?

Damn Rob, I got a Banjamin Whisper, 1250 FPS with .177 alloy pellets. I got a bigger variable power scope on mine now. Pretty quiet with that muzzle baffle. Never hit anything larger than a mouse on a fence but I can put 2 pellets in the top of the "B" of a Budweiser can at 50 feet. Im actually looking for the .22 barrel for this. I thought you were not supposed to clean a pellet bore? Something about the lead lining the bore? Hard to believe that barrel doesnt bend when you break barrel **** it. Its a Nitro gas cylinder, no spring.
