Sharp Shooter,

Now you've got me checking some old guns I don't shoot that often..LOL, they are fine.

As far as why some get brown patches and others don't, I can only speculate that it's in the preceedure being used or some environmental issue. Like everything else in this game, whatever one uses that works is what they shouldstay with.

I have a .54Lyman GPR and while it's 32" bbl. was a good shooter, it was also a little long/heavy for my ground pounding style of hunting-I bought it new and never had trouble with rust. I purchased a shorterused Deer stalker bbl with a nice enoughbore and reworked it to fit on the GPR, first few times I cleaned it with my warm water/dawn dishsoap/BB routine I got brown patches in a few days. I ended up soaking the bore with carb cleaner, bushing and cleaning the heck out of it, took awhile but it doesn't foul the patches anymore. It looked and felt clean befor I started so I don't know what was in there or what the previous owner did to clean it but since it's OK now there must have been something in it.
