Home Forums Hunting & Shooting Single Shots Ruger #1 450 vs 45-70?

I'm looking at acquiring a Ruger No.1. I'd like it to be a nice 45 cal. Looking at either a 450 Marlin or a 45-70 Gov. Any thoughts or experience would be helpful. Ammo availability for both seem scarce. I know the 450 Marlin has a little more velocity. I have plenty of 45-70 rifles and one 1895 Guide Gun in 450 Marlin. I like them both.
