.225/5.56 Case Capacity Report

[Grump]

From a Colt HBAR barrel, averaging 5 readings each:

<span style="text-decoration: underline">LC NATO cases:</span>

31.35 gr H20, case length average 1.7516


<span style="text-decoration: underline">LC M193 cases</span> (I have some old stuff...):

31.15 gr H20, case length average 1.759 (time to trim...)


<span style="text-decoration: underline">WCC cases</span>, mixed M193 and NATO headstamps:

31.56 H20, case length average 1.756

Now, I just got a bunch of once-fired PMC brass. I hate de-crimping primer pockets. Can't use the RCBS tool on the Dillon.
