� The factory brass wasn't made to the specifications that were integral to the original design. (Bruce took it on himself to "improve" something that didn't need his "improvements.") But Joe diligently made some of those cases work safely � with muzzle velocities very close to predicted and very small groups (as small as 0.291 inch, right?). �
IIRC, the hundreds of cases that I gave Joe are from
two production runs, months or more apart � which gave Bruce a second run at "improving" the first batch.
IIRC, he said that he'd made the head of the case stronger � how, I don't know.
Those cases are probably "right on" in exterior dimensions and vary all over the place in interior dimensions.
In all my computer simulations, I've used an onager estimation of gross capacity.
I'd like to see what that cartridge can do with selected cases carefully formed and trimmed from good .25-06 brass.
