Gentlemen; i have a Disc elite that has never given me better than a 4" group at 100 yds. i have tried a variety of bullets. It seems that the 300 gr. xtp are the "best" with Pyrodex. What other combination suggestions do you have? I love the gun but am a bit perplexed with the poor groups compared to some that I read about on this forum. I have changed scopes and mounts. That does not seem to be the problem. It currently has my Leupold 1.5X 5 on it. Thank you
