Actually,Snuffer,I think it not a problem at all.I run a cotton flannel to breech before snapping a few caps,this forces the debris into the flannel rather than into the barrel where a swabbing may push the remnants toward the flash channel.The flannel will clearly show a scorch mark and I find the flash channel quite clear.If hunting,I will sometimes remove the cone and run a pipe cleaner through.As for leaving the weapon loaded, one need not worry so.I have read many studies that indicate it is the BURNED powder residues that are corrosive,the salts and other by products.As long as the powder remains unburnt it is chemically stable.Now,one must keep his powder dry.How could it be dampened? Obviously, a dunking or rain but more likely bringing a cold weapon into a warm environment resulting in the formation of condensation.On a personal note,two weeks ago I killed an eastern diamondback rattlesnake in the back woods of my property.All I had at hand was my third model dragoon,which I might add was snapped and loaded in 2005.Killed the serpent dead and not a misfire nor hesitation.I checked the chambers for any signs of corrosive "ringing" and found absolutely nothing,chambers nice and clean.Yes,powder is hygroscopic,but if dampened it just separates into it's components ,not good for firing but not particularly corrosive.Burned powder residue is corrosive but unburnt powder will not eat up a gun.Best regards,J.A.
