I finally got a chance to shoot my .54 gain twist that R.A. Hoyt did for me, which gave me an opportunity to try my new magnetic cleaning mechanism. I am super pleased with both!!! This tool took me back 40 yrs, when I used to just take down my T/C Hawken and stick the barrel in a bucket of water, and swab away! (now, my flintlocks all have pinned barrels) What a simple and effective idea!
