Well to each his own.
I spend 500 to a 1,000 dollars on a gun I spend time and money getting it set up so it will do what I expect when I do all that I just am not going to shoot any powder but what I like best in that gun, I just think that after getting the best of every thing else in my opinion it pretty cheesy to quibble over a few dollars difference.
And I have yet to have any experienced person that I had respect for tell me something else was better.
What other powder will give 2300 fps + with the same pressure that a 120 grain load of 777 produces? What other powder can you shoot all day and will maintain accuracy with out any swabbing or cleaning? When I used 777 I spent more of my shooting day cleaning out crud ring than all of the rest of the day put together, its is worth the difference in price just by it self for that not to mention getting fine accuracy with loads in a FPS range I could not get with reasonable pressure with any other powder.
Every body has the right to choose its still a free country, I am glad to see some people use Pyrodex and Black we need to keep them in business so we have powder for our Traditional guns they are fun to shoot to. I sincerely wish something as good or better than Blackhorn would come on the market as improvements come from competition but so far I see nothing that even is in the ballpark.
