My cylinder is straight away, no canted cartridges. But, a Six Shot .45LC in a cylinder that will fit the Remington doesn't leave much room to play with! I think as long as one stays in the recommended limits 34 G of BP or Cowboy Ammunition loaded for a maximum muzzle velocity of 750 to 850 fps., you're in there. By the way, the cylinder I got from Taylor's fits better, locks up more soundly than the original, and is machined on CNC equipment. Hope that helps.
