I purchased a 50 cal original disc rifle a few years back, I used T7 fff 70grains of powder, for bullets I tried 200 & 250 grain shockwaves. didn't get real good accuracy with either , what am I doing wrong. do I need to increase my powder charge ? what do you recommend ? how much powder do I dare use in this gun? I really like the shockwaves in my other bp guns.
Thanks Steve
