I run it through the neck only.....Winchester brass is very good but still has dents in the neck. IMHO, you don't need to do a full resize. Measure a few, and if they are close.....go for it. Regards, Rick.
I'm with Rick. Why work the brass, or have to clean the brassone more time???? I make sure the necks are round, deburr them and load my load.
No brass is going to give it's best accuracy untill it's fireformed anyway, so i see no sense in another step in sizeing new brass.
