At a certain point there just isn't practicality to rifle caliber handguns. They aren't that much lighter than a 16" lever, and you can certainly shoulder and accurately fire the rifle faster than effectively drawing and firing said revolvers.
I mean a BFR weighs around 5 pounds, a S&W 500 and similar revolvers start around 4 pounds and go up quickly, and a 1895GS is 7.
Ballistics for large rounds like 45-70, 460 or 500 S&W they loose velocity so fast from shortening barrel length that anything below 6" is too small and you really need at least 8 or 10 inches of barrel (insert adolescent humor).
