There is a lot of confusion of all of the .455 guns. The .455 is loaded so low so it can be shot in the old made in 1882 guns not that the made in 1918 guns wont hack it. Pretty much a myth that people just wont give up on as MK-1 ammo ran twice the pressure as the WW-1 ammo does. Go .45 ball no that will beat the gun loose in time but lead 250 grain slugs at like 700 750 FPS they will survive better than a colt will.
