If you watch your money real close you will find Pyrodex the best choice, it has the best price every where I have check. If you don't live in a high altitude you will likely get crudring from 777 and thats more trouble than any powder is worth, at 25 a 10 oz can + shipping and hazmat Blackhorn is real close to the same as 777 is where it is available to me but since I would not use it anyway its immaterial as far as I am concerned. Some times expense has to do with the way you look at things, not having to scrub the crudring out between every shot made shooting much more enjoyable for me, not having to do any swabbing or carry any cleaning stuff when hunting was an other step up and when I found it was a progressive powder which I could go beyond the point where constant burn powders were burning after they left the barrel that was a serious difference in capability. There is also a difference in burning peak time and a pressure advantage. I would say to you to try them all over time, You will soon find out what is best suited to the type and kind of gun you use and your own preferences. If you have traditional guns Black or pyrodex is best, if you have one of the ones with difficult ignition Blackhorn is not for you. Lee
