I guess it depends on a couple of things, when I used 777 I got crudring really bad it was a 5 to 10 minute job just to get the gun clean enough so it could be loaded.
Now my time is limited and when I have some shooting time thats what I want to do not scrub a nasty hard crudring. When I tried Blackhorn and found that not only could I not clean the gun actually groups better that way and according to the records I keep I got rid of 70% of the unaccountable fliers that had occasionally bothered me.
The other item I ran into is that when I did my pressure testing I got the same velocity as 777 but an average of 15% less pressure so the pressure peak is lower and flatter with the same load. which means I can load 15% more and get more velocity. Because of the fact that it is progressive burning rater than a constant burn powder it pushes the heavy bullets better velocity wise than a constant burn powder.
And then there is the supply the local gun shop has it but they also charge about 6 dollars more than I can get it from Powder Valley for including the has mat fee.
The price is a about 3 dollars higher than 777 bought the same way here, of course there many be someone who knows where to get 777 cheaper as I have no interest in the stuff after using Blackhorn.I buy my Blackhorn by the case from powder valley with hazmat and shipping it costs me 27 dollars a can for the last batch I bought.
There are some people who do not get crud ring and there are some who would scrub all day for the difference in price and who are not interested in the fact that you can get more velocity for the same pressure. It really depends on what a person prefers and what they chose to spend there money on. Lee
