********************
That bullet is a .312 and my case capacity seems to have increased with subsequent firings, i think fire forming is a longer process than i thought - more like 4 fireings than 2.
Case volume is 62.3 now
I am who I am - I am not who you want me to be.
Therefore I am me.

Treeman, how do you measure case capacity?

Is it 62.3gr of water or 62.3ml?

Difference is water capacity. My scale is on grains for reloading, I see what you getting at

difference in grams is actually water capacity in ml at coast.

So it is 62.3 in grains. :-X

Changed the case volume.

Ds J

4.16 cm³ (64.2 gr H2O)

7.62 Russian

Same bullet diameter.

Treeman

.303 British .311 or .312 depending on which was chosen for the bullet by manufacturer.
