Here's the question. I've been cleaning a number of rifles that were put away dirty 30 to 40 years ago. These are MN 38's, M44's, 91/30 and a few 308 2A Ishy's. I don't think some of these firearms have seen a brush in my lifetime. While most have really nice bores after being cleaned, I was wondering if there is any tricks to speeding up the process.
