I have a Pa Pellet 50 cal. . That I have had for 2 years and I have used power belts , Maxie hunters , and sabots in it . All have work out nice but I would like to use round balls in it . Any advice would be great on patch size , balls, and a go powder load to start with . I use 3f in the pan and 2f down the barrel now . I love working up loads with this just a starting point in needed . I will not be starting right away . It will be a in between season thing .
