How's you work with the 450gnr coming?

I'm interested what your going to get the 500gr bullet vel up to. I am seriously considering having my 20" 45-70 encore barrel rechambered to the 450gnr. I think this 45-70 is a 1-20 twist. What is your 14 inch 450gnr? Will this be an issue?

What I am thinking is the 450gnr with a 20" barrel could crowd the 458 Winchester.

Thanks!
Mark
