Q. I have an older Thompson/Center New Englander muzzleloader that I purchased used. It was corroded from improper cleaning. I have cold-blued the barrel and it shoots well. However, I shoot it infrequently. When cleaned with soapy water and stored with natural lubes, the bore begins to rust. I am aware of complications of using petroleum products in the bores of blackpowder guns. Is there a cleaning/storage method you would recommend?


A. After more than 60 years of shooting both original and replica blackpowder arms, I have not had a problem with rusting bores in either type. My system is to wash out the bore with sopping patches at the range using a mixture of hand dishwashing detergent and water. Then, when I get home, I strip the gun down, remove the breechplug if applicable, and clean the bore with a bronze brush and more of that solution. Next, I rinse it with hot or boiling water, wipe the bore dry with patches and then apply a good preservative oil. For external protection, I often use a light coat of automobile wax. Despite having lived near the seacoast for many years, this procedure has kept my guns rust-free.
