Somewhere in the books it says that lever action long arms can be "fanned"
with the same penalties as a pistol. The rifles actually have an advantage
in having more rounds per load so you aren't gonna be empty as fast.
In play we only had one hang up. Non-lever action rifles didn't seem
shafted by being slower to fire. The hitch was the lever action shotgun
that was found. Damn that made a mess of a bad guy on a good shootin' roll.
'Course it only held four rounds, so it did empty quick. I'm not familiar
with the weapon in real life history, whether it had reliability issues or
not. I did rule that it had to use metal cased shotgun rounds -- whether
factual or not I decided that the paper cased rounds might crumple or
deform. This weapon was no more of a problem than the one Colt revolving
rifle with insanely high damage dice... and I could always use them
_against_ the players...
