I have been shooting Knight 240 gr sabots with 100 gr of Pyrodex pellets out of my 50 cal Disc rifle with good results (2" groups at 100 yds). I know I probably should not try and fix something that is not exactly broken but I would like to see if I can get the gun to shoot better. I am going to try the Triple Seven FFFg powder and the Hornady SST bullet. I was going to try the 250 gr SST but I have been reading that guys are finding better results with heavier bullets out of the Knight rifles. My question is should I be trying the 300 gr SST instead of the 250 gr SST? With my current recipe with this gun I am getting about 5 inches of bullet drop from 100yds to 150 yds can I expect a little flatter shooting going to Triple Seven and the SST' s??
