Are the .44-77 BN and the .44-90 BN viable contenders in modern Creedmoor

I have 2 different prints, one from Dave Manson and one from PT&G. I will dig them both up and post them. The big difference I see in the 2 is the neck diameter. I also had Dave change the throat so that its a taper from the case mouth OD to the bore and most likely that is the design I will go with. His has a larger neck diameter and that will just let me use GG bullets as well as PP. I would like to avoid having to ream the inside neck diameter to be able to use GG bullets if I can.
