How to measure case capacity tutorial posted.

Recommended Posts

Very nice. It doesn't take as long as some think yet if gives you lots of comparison values.  When you look at book value capacity it is often far different. I have a 20 TAC and a 20 PRAC. The PRAC on paper should be bigger but due to reamer sizes etc. my two are identical. Great for loading tests but book value telling you XXX and you have YYY you maybe over doing it or leaving a bunch on the table when going for the gusto.

According to Wikipedia the specs say 3.40cc for the 6.5CM. The Starline was 3.33cc and of course the rest of my reformed were very close to the same as Starline. Less than 1% over the entire lot except for the PMC brass which was 3.14cc.

It is kinda neat and eye opening when you measure case capacity.
