WellI had been shooting 100 grs of 777 pellets and 250 gr Hornady SST's out of my T/C Omega and getting ehhh, just okay groups. Well today I tried 120 grs of loose pyrodex powder and a 240 gr Hornady XTP. WOW! What a difference. Here is my first three shots from 100 yards below. I think I can live with groups like that from a muzzleloader. LOL! The added benefit is also that the pyrodex powder and the XTP's are much cheaper to boot. Now please tell me that these XTP's will do well on deer.
