While looking down the barrel of my recently acquired 600 OverKill I began to wonder where in the hell can I get cleaning brushes? Shotgun brushes...16ga?

20 ga bore diameter is 0.615".

Or, as Kynamco UK sell one brush to cover both .577 and .600 Nitro, a .58 cal muzzleloader brush should work.

I use a 20 gauge bore snake on mine.
