kinda goes down at an angle from the back... I don't think there is a current cartridge ( maybe 50 Browning or bigger... case wise ) that couldn't fit... I think all the really long straight case black powder cartridges will go in anyway...
I still have a bunch of stuff for the 577 Snider... almost built a rifle for it a while back, but all the chamber dimensions, loading dies, & brass had too much variances, & case life would have been pretty short, or cases needed annealing too often, so I shelved that project for a while... might want to pick it up again later...
