Pioneer powder has 50 gr "stichs" ,I have not tryed it ,I use 777 pellets . If it is the same as the old Clean shot powder I tryed it years ago (loose) it worked good but the next spring I reopened the sealed bottle to find a 1/2 lb solid mass of what used to be powder ,I talked to others that use it ,they agreed that after 6-8 months ,throw away what is left . Maybee they have solved this problem.
