I don't see them, but are there any big bore pumps and autos out there? I'm talking grizzley worthy.
Most I know of are the BAR in 338 Win Mag and the Rem 7600 in 35 Whelen.
I'd sure love to see a BAR in 450 Marlin, I think it's totally doable and should be done, since they have the BLR in the same round.
Also love to see tube fed pump actions in 444 Marlin and 45-70.
I have an idea for converting an AK type action to 444 Marlin, sure hope the specs check out and indicate it's feasible.
