Always used a rod, brush, and jag. It's what dad used. I don't think easier equates with "as clean".

I do have a 12ga. boresnake, though. I don't clean the bore of my shotguns with it, however. I clean the shotguns with the old rod, brush, and jag. What I use the bore snake for is getting the dust/lint out of the end of the bore, when I get it out of the safe/soft case.

I was born in the fifties, though. I'm not one to go in for "new-fangled" things.
