i tried it and really liked the powder . it burned alot cleaner and it seemed to shoot alot faster , i was shooting from 200 yds and i could hear the bullet impact on the target i put up 2 2x6 boards and it went clean through both of them , it seemed to get down to the target alot faster . but i was shooting 140 gr of powder with a 240 gr / sabot . it also didnt leave alot of smoke in the air , i use to shoot the pyrodex select but now i like the 777.
