RE: 777 or Pyrodex
I talked to a friend that was involved in testing white hots according to him they shoot the same velocity and leave the same crudring as 777 pellets.
You may have too try 777 to tell what will happened there are a very few people [I think theres a secerate to it that some of them may not even know] that have no problems with it, then there are the ones like me that it shot accurate for but the crud ring was so bad that it took me 5 minutes cleaning time for every shot so I spent a lot of my shooting time cleaning and had to carry cleaning stuff to be sure I could reload while hunting; and while those are the opposite ends of what goes on, there would not be so many people that love BH and are willing to pay the price if it were not for these type problems with the other subs.
