I guess I do not understand the way some people are viewing this subject.
First off all of use that keep some Traditional or older inlines use some other powder in them, I keep black and Pyrodex around all the time, that has nothing to do with the horrors of 777 or the benefits of Blackhorn. I do believe that from the people on here who I TRUST that we experience different levels of problems from 777. Those of us who experienced the worst level have a hard wide ring right above where the bullet sit and it takes 5 minutes or more to get it out with what ever you use I tried everything I could think of and everything that was suggested. Now Pyrodex and black have never been a problem to me I clean them and think nothing of it.
I also believe that some of the people that have lessor problems with 777 do not understand the problems some of us have experienced.
As for the cost of Blackhorn I buy in quantity because I shoot it a lot and my cost runs from 22 to 27 dollars depending on where and how much it recently took a drop when the #5 actual pound containers came out. If I bought in the local gun store it would cost me 32 dollars and by buying in quantity my BH price over laps the 23 dollar cost of 777. If you chose to buy the local way it is high.
I guess my opinion is every one should use what works best in the gun they are shooting for them and not complain.
