Try the 240's. Which rifling do you have? My 94 shoots 2 inch groups at 100 yards with open sights, I am very happy with it. Especially with my eyes. I do not think Hornady has the 44 mag. ammo out yet, but they are coming out with alot of new caliber's. Are you shooting pure lead or jacketed? Did you shoot jacketed after you shot lead bullets? Your barrel could be leaded, or there could be copper fouling. Lead and jacketed bulletsdo not mix well in some rifles.
