I originally used triple-seven to sight in my omega.It was terrible.I was using 245 grain power belt aero-tips.All my shots were good windage wise,but vertically the spread was almost 24 inches.I switched to Pyrodex with the same bullet and 5 shot groups tightened up to a fist-size group at 100 yards.The difference in just the powder was incredible.Anyone else with similar results.My gun will not shoot triple 7 pellets with any accuracy.I cannot wait to see what I get with a scope.Oh and my 200 yard shots drop about 12 inches.At both distances I use 90 grains of powder.
