i just tried some of this powder in ffg as im a gimmick geek and their claim of much cleaner burning seemed to be appealing. man let me tell you...this powder is the absolute best thing ive ever tried....cleaning my tc new englander took like 10 mintues. there is hardly no residue to begin with and what little there is cleans up with water....it takes about 65% less time to clean the barrel and nipple than it used too. and thats after leaving it for 3 days fouled!!!! with pyrodex or even triple 7 the damn thing would have been rusted up...if you can find it you need to give it a try. just wished i would have tried it in my inline instead of using the triple 7 pellets i had. as a benefit.....the gun shot great too.
