Ready to get a reamer ordered for my new build, and will be using Norma brass in my .220 Swift. Loaded new brass is miking at .253, what would be the smallest neck diameter reamer to order based on this spec? I don't want to turn necks, but I don't want headaches with too tight a neck diameter, this rifle to be a dedicated long range Varminter, and very casual paper puncher. Looking at either .256 or .257, which way to go and why? Thanks!
