BS
I cant say if it does make a difference or not. I have shot the center hammers over the years, Winchesters, Remingtons, Stevens, as well as the side hammers sharps and trapdoors.
When the striker or center hammer hits with the fast lock time your still fighting the torque of the heavy bullet in the bore at the slow velocity it travels down the barrel the torque and recoil moves the barrel before the bullet clears the muzzle and it the shooter does not control the rifle all the light fall of the hammer and fast strike of the short throw of the hammer or striker in my opinion dont make much difference at black powder velocity's.
Except maybe piece of mind to the shooter
