Since getting my John Hancock rifle, I wanted to follow PVA’s recommended cleaning procedures. I’ve had my rifle to the range one time, shot 40 rounds, and cleaned it using their recommendations. I ran about 15 patches through it until the patches came out clean. However, I wasn’t using their recommended cleaning solvent, I hadn’t ordered any at the time. PVA recommends Bore Tech Eliminator for cleaning their barrels. I ordered some, sat down this evening and I ran some patches of it through my “clean” barrel. Holy cow!! I don’t think I’ve ever had anything clean copper out of a barrel like this before, especially a clean barrel. Here’s a pic of my patches. The first four are wet patches, and the next two are dry. I think I found my go to cleaning solvent.
