I spoke with Shawn Carlock on the phone a few weeks ago, he was very helpful in answering my questions, if i weren't doing this myself he'd build my .338 Edge.
Anyhow case capacity was brought up referencing quickload, and I figured I'd share my recent unfired measurement using remington brass. Filling the case LEVEL with a new CCI 250LRM primer pressed all the way in netted me 115.2 grains water capacity. Using the overflow method I got 116.0.
The argument between the .338 rum and .338 edge seems to be settled, someone else out there is making the equivalent of a .338 Edge with .338 RUM width dimensions (fire form required). That to me seems like a better argument in regards to a negligible gain. Thanks for the insight!
