It's hard to get things like the 44 Remington Magnum to shoot consistently under an inch at 100 yards but easy with a 204 Ruger.
I beg to differ. The cartridge is fully capable of sub MOA precision. The gun and/or shooter may not be. Were I inclined to purchase a .44 barrel for the Contender I'd be gravely disappointed if it did not run under an inch at 100 yards.
