Man, if you are gonna survive here, you can't clean your gun.
I have a Dewey rod .22 and I have jags from .22- .45 for it. Think I have an adapter too for using shotgun bore brushes, but I just pull a snake willth a little oil on those every so often.
I can probably save you some money. I have a couple hunting shotguns- Browning auto 10 ga. and a Benelli 12 ga that have never had a rod down the barrel. Both have close to 30 years of hunting on them.
My trap gun- a Beretta auto, last had a rod down the barrel in the late 90's it's over 80,000 rounds since.
