0.9" 3 shot group 100 yards
In 2000 I paid $180 for this 1962 Ruger.
Then I blew up the muzzle with Lead fouling.
I could not find a new barrel.
Then I saw Marlin 444 micro groove barrels, new old stock at Numrich for cheap.
I realized that if I cut the rear off the chamber, the part that was left was close enough to a 44 mag chamber.
So cut off some breech, drill a gas hole, and voila, I have the world's heaviest and most accurate 44 carbine.
I no longer shoot cast bullets in it. Now it is a steady diet of 240 gr JHP 24 gr H110 and a mean roll crimp.
I am old enough to remember the magazine article when this rifle came out. It said that the carbine could take high velocity ammo, but the revolver could not. They are doing just fine with the same handloads now.
