I have been contemplating trying some BH209 in 1 of my Sidelocks i have setup with a Magspark nipple and use Fed 209A primers i have on hand. I have a pound of BH here to try. I wonder how it would work with a 530 Grain Paper Patched bullet? I am thinking of trying it in the ‘Business Rifle’ 32” Green Mountain 1:18 Twist .451 Bore. Sure be nice to cut the fouling WAY down and be able to load without Swabbing between every shot (tho I probably would anyway) I would think my steam cleaner would get the Carbon, and any gunk out of the Snail/Patented Breech like NOBODY’S business? Just do the barrel first with hoppes #9 as mentioned above until i have the Bore fully clean, then Steam Clean the Pee out of it through the Nipple hole. I wouldn’t worry about my cold clean bore shot, as this is strictly a Long range bench/target rifle, i would load and ‘Burn’ my first shot, Then start my Group work. Any thoughts about this idea?
