I am in the process of setting up my sizing die.
i am using my hornady head space gauge with the .375 bushing and measuring the shoulders of my fireform cases. I am getting quite a bit of variance on the shoulders of my once fired lapua brass. ranging from 1.1935-1.198. a new unfired case measures 1.185
then i have some hornady factory ammo i bought and fired it was 1.191 before firing and after they are very consistent at 1.197
i also have some 2 fire ppu wolf brass. don't have a before but fire form it goes from 1.1955-1.1965
my question is do i have a head space issue because of the variance in the lapua cases or is it because the shoulder started off so low?
my thoughts are to set back to 1.195-1.194
what are your thoughts? thanks
