Sixgun/Levergun Combinations

By John Taffin

September/October 2009 Handloading Column

Sept Handgun Loading

A good all-around .357 Magnum load for both levergun and sixgun is the
Lyman/Thompson #358156 gas checked bullet over 15.0 grains of #2400.

An early writer for GUNS Magazine, Kent Bellah, wrote articles that always caught my eye, and in my youth, I paid attention to his stuff. The article I remember which influenced me most was entitled “The Two Gun Man Comes Back”. With this piece Bellah hearkened back to the time when it was normal for one to carry a sixgun and levergun chambered for the same cartridge. He had a 31/2″ S&W .357 Magnum which he mated up with a custom Model 92 Winchester converted to .357 Magnum by Ward Koozer. I really wanted such a combination, however it would be nearly 25 years before it became reality.
