When you stop and think about it, feeding two straight-wall cartridges of different lengths is asking a lot of a lever action that was designed to feed tapered revolver cartridges of one length.
I had a friend with a B92 in 44 magnum, back when you could still buy them new. I got to shoot that one on a couple of occasions and it really impressed me. It was slick as snot but I don't recall him ever trying 44 Specials in it.
My more recent experience has been with a single example of Rossi's 92 in 357 Mag. Standard length 38s would flip right out the ejection port if unless you worked the action so slow as to render it useless as a repeater. You could literally have run a single shot faster.
