1916 vintage .455 MKII HE with a post war 45 ACP barrel and cylinder. The .455 barrel was bulged.
Cylinder is bored out for 45 Colt.. I use 45 Win Mag brass loaded to old Colt velocities in moon clips. Puts the bullet right at the forcing cone.. No Jump.
Surprising how light it is with all those big holes in it.
