I am within my first month of owning my first single action revolver: The Ruger Super Black Hawk - Hunter, 7-1/2" bbl, and in .44 Mag caliber.
Initially, I managed to get 2-2.5" groups at 50 yards and from 3 to 4 inches at 100 yards with 240 gr SWC cast bullets. Later, I try some loads with jacketed bullets, 240 gr HP/XTP's over 12.5 gr of Blue Dot. Results here were 4" groups at 50 yards.
I tried the same 240 gr XTP's over 18.0 gr of 2400 and the group shrink to 0.9" at 30 yards.
