Yep i sure do! Just a Few Good Tight Fitting patches down the Bore. With Nipple Removed, i use my Air Nozzle from my Compressor and BLAST Air Through the nipple hole, This Forces oils from the Breech up in to the Bore, Then another Couple of Tight fitting Patches back down the Bore to pick up any Oil i Blew out of the Breech Area.

I take it 1 step farther when preparing to load a Rifle for Hunting, I do the EXACT Same procedure above, But i also use a 1/4-28 Magspark 209 Nipple and Pop 1, maybe 2 Federal 209A Primers Straight Through (These are HOT 209s!!) Then i run 1 Dry patch Down, You will get a LOT of Black Soot on that Patch From the 209s, Then i CONFIDENTLY Load the Rifle to Hunt. This mimics/simulates a Foul Bore BEAUTIFULLY, My Cold Clean Bore Shot is DEAD ON using this Method
