I've been thinking of making one of my Handis into a more versatile gun, one able to handle both shot and bullet.
I read a long time ago about someone who bored out the muzzle of a 45/70, about 3-4 inches , then used both 45/70 ammo and brass loaded as a shot cartridge. Supposedly the muzzle boring allowed time for the shot to quit spinning in the rifling and produce a decent pattern while the bullet just had a shorter barrel.
My other thought was to take one of the older 44mag barrels, which are somewhat oversize, chamber to 45 Mongo(Mungo), bore to remove all rifling to an inch or so of the muzzle. This is the way the old Paradox/Cape guns were bored. Then use the .444 brass to load shot or a .452 lead bullet. This should produce at close-up shotgun and rifle.
Am interested in your thoughts, opinions, ideas or suggestions of either of these ideas.
