295gr. Powerbelts shoot great out to 100 yards. SST 300gr. shoot great out to 100 yards. 300gr. Pistol bullets shoot great out to 100 yards. In fact anything I put in the barrel shoots great out to 100 yards. I don't check beyond that as that is the limit of my hunting shots. Pyrodex works good but is messy, Tripple Seven makes a hard crud ring in my Omega so I quit using it. Pioneer works good. Black Mag'3 works very good. I just got some Pinnacle and have not shot enough to decide yet. I find most sabots difficult to load and have switched to Harvester sabots so I can load the bullet without a ton of effort.
