i am considering getting a new remington nma in stainless steel. most likely uberti because you do not have to grind the loading port for conical use and the price is close for the pietta or uberti. then there are details, like what is the chamber size for the latest crop of uberti rem nma’s, .454“? i would plan to use buffalo arms or willams sports as a supplier, neither of which i have experience with, is any one better than the other?
