I will be bringing both, just in case. I might also bring my marlin 45-70(although that might be a bit much for white tails)
On second thought take the Marlin and leave the other 2 at home. Most Marlins will handle modern ammo. I don't even know if there's any that won't (45-70). You'll get about 1800 fps out of a 300 grain JHP. It's a good 200 yard cartridge for deer if you are good at estimating your distance and remembering your bullet drop.
