Well I had used the substitutes in my BPCR's but due to no real stuff available here never tried real in them. Well I acquired a # of BP RS and now you people have really started something. The clean up was a s easy or more so than smokeless and far easier than Pyrodex , the accuracy was great at 200 yds. and the recoil very easy more a push than a slap. Thanks a lot. I am hooked.
