DO NOT FORGET TO INCLUDE THE COST OF A NEW HIGHER FRONT SIGHT. The 44-40 200GR bullets will shoot four to six clicks under the 240-250GR bullets of the 44SPL depending upon the propellent and charges used.
IF you decide to just shoot 200GR bullets in the 44SPL cylinder you might as well save your money as the 44-40 can and will do everythying with 200GR bullets that the 44SPL can accomplish.
ON the other hand, my COLT NEW FRONTIER 44-40/44SPL convertible shoots like a champ with both cartridges and ALL bullet weights.
And so it goes...
