I shoot a Triumph and recently had problemsshooting tight groups when using 100 grains of 777 with a 250-grain Shockwave so I switched up from pellets to BH209 powder. This stuff is awesome. The sabot seated in the exact same spot everytime I loaded the gun, even after shooting it 10 times in a row without swabbing the barrel., where as the 100 grain pellets I used to use would not allow me to get a consistant seating of the saboton top of the powder.I was shooting 1/2 inch groups at 100 yards consistantly.I will never go back to using pellets from this point forward. BH209 is awesome and I highly recommend it.
