I'm not a pellet guy. Black Horn is a great powder. I shoot traditional black powder in the flintlocks so I'm not concerned about loose powders like 777 for clean-up, you still have to clean after shooting regardless what powder you use. Is Black Horn worth the extra $, only the shooter can make their own decision. BH burns cleaner leaving less residue and has some extra moisture resistance. I'm nearly out of BH and I am out of 777 so I get to go to Bass Pro and probably purchase both. If you're shooting anything other than an in-line don't shoot BH, this is a direct statement from BH representative. It states right on the label for 209 in-line muzzleloaders. Heck, I still have Pyrodex RS coupled with a TC Maxi-hunter HP in the TC FireHawk will give 1" groups @100 yds. My son prefers 777 in the same ML'der. BH most likely won't make you more accurate maybe just a tad happier on the clean-up end of things. I'm sure you will get a whole host of in-put on this subject and rightly so. That's my take!
