My 94 375W will feed loads with the 2.080" 38-55 brass just fine, not sure about the longer 2.125" stuff, but I would guess probably not.

It actually shoots .378 cast a lot better than .376 or .377. I haven't tried anything over .375 jacketed in it.

.378" 245gr RNFP in 375W brass over 10.5gr Unique from 50yds.
