Re: water proofing barrels
This may sound funny, but it works. I was shooting a lot of competition in the rain a few years ago and was having the same problem you describe. I had read about waxing firearms to protect them, so I completely stripped one of my competition rifles (model 1873 in 357mag). I degreased it and waxed it with Carnuba car wax. I put 2 coats with a buffing between (on all the external surfaces) on the barrel, action and other metal parts. I then oiled all the internal parts (as per normal) and re-assembled. I shot that rifle for 2+ months (probably 20 days outside at least 1/2 of them in the rain). It never rusted AT ALL!
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
