I used to think the .44-40 took a .427 bullet and the .44 special/.44 mag. took a .429 dia. bullet. I have two .44-40's one taylors schoefield in .44-40 and one smith model 544 in .44-40. I loaded some .44-40 cases with .429 bullets and they went into the revolvers cylinders jsut fine!so I could shoot .429 bullets with either gun! I've been resizing my bullets for these guns to .427. now it looks like I wan't have too. is something wrong with me and/or my gages??? or is this a deal like the long colt went from .454 dia to .452 like the .45 auto???(I was playing with motorcycles and Airplanes when this happened.
Now neither gun will take a .44 special case, I have to load .44-40 cases for these two guns.
any one?
