I've got a 44 mag trapper that has seen very heavy use over the years--same pre-lawyersafety vintage as your 94. The only problem I ever had was one common to trappers--magazine tube would come loose. That was fixed by my gunsmith years ago, and it's never bothered since. The plain-jane 30-30's are, from my experiences, pretty much trouble free. The biggest post-64 lifter problems were pretty much solved by Winchester when they changed to a cast-steel one instead of the tin stamping that they had from 1964 to around 1971 or thereabouts. I've never had a .357 version of a 94, so I can't relate any bad experience regarding lifter problems in this pistol-length cartridge, but my 44 mag feeds anything I load into it.
