Thread: Light Primer Strikes

Greetings @Moa Hunter,
The dies are likely cut to US SAAMI spec but this is out of line with the spec being used in Finland. Unfired and fired Lapua cases from the T3 measure almost the same, both made in Finland, so I am assuming that the cases are max and the chamber is min. The Ruger factory rifle is longer by 0.005' so this would be a max chamber on the Finnish spec. Only the US dies are out of step.
Regarding the Redding Competition shellholders I find that these give a more precise sizing than backing of the die based on my measurements. I also have more than one rifle in .308 and 6.5x55 so the shellholders are a better way of setting the case headspace instead of having to adjust the die. My VSSF .223 is spot on with the standard shell holder and my T3 .223 needs the +0.002" so I borrow a shell holder from my son for any sizing for it. For My SAUM which I don't use mutch I will probably just set the die as you suggest.
Regards Grandpamac.
