Our 416 HSM will have about 25gr more capacity than regular
50bmg, and as for actions if you add up the fat bolt non-bmg
actions, with .750"- .800" bolts, there are about a dozen, some priced
pretty reasonable.
For 416 HSM we can use a EU made primer I have some of, that
is tamed down a little for smoother ignition, and its cup is harder
than CCI 35s , so we can go quite high pressures. Rigging up
hydraulics on my huge press for easier case shaping.
When few cases fireformed we'll have exact specs for reamer guys.Ed
