Does the SB die re size the head on the brass? I have been reloading for my Tikka T3 Varmint in .223 in some once fired brass I picked up and I'm only able to close the bolt on about 70% of the cartridges I load! After carefully checking them all and finding all measurements to be perfect I noticed the heads have nicks and marks... even warpage on a few and when I gently file them I was able to close the bolt on a few more, but not many. I was using full length pacesetter, Lee dies and figured I'd have no trouble, but now I'm looking at throwing away a bunch of brass that I don't want to.
