Let me let you in on a little secret. "IF" you're reloading for a Ruger No.1, full length size all your brass. Neck size twice and the case will no longer chamber.
I have owned at least a couple dozen Ruger No. 1s, made from the 1970s to very recently, and have NOT found that to be universally true. Or even generally true.....
The No.1 I have won't accept neck sized cases. I had a H&R Handi-Rifle that neck sized cases would stick. Switched both rifles to FL dies. Never had another stuck case. The No.1, you couldn't chamber a neck sized round. The Handi would accept a neck sized round, but wouldn't extract the fired case...unless it had been FL resized.
