.375 Cheytac. It's a...significant step up from the .35 Whelen and perfectly legal. Along with the .378 Wby Mag. It's pure idiocy that we can legally use .375 Cheytac and .378 Wby but not a .30-30... I'm using an XP-100 in .350 Rem Mag during the late "muzzleloader" season. Comfortable to 300 with it from a good rest out of the ground blind.
