I was at a gun show and bought a set of new in box 300sav dies made by Schissel they were still packed in cosmoline in the original box so I know they are new. My son has an old 99 and with the price of ammo for it going thru the roof I knew it was just a matter of time before he popped the question! Well I went to work reloading some for him and the dies don't seem to size the neck down far enough to hold the bullet. Was the older brass thicker in the neck and if the newer brass is thinner do newer dies compensate for the thinner necks?
