Guys have asked about a 10ga FH, and it is just
getting stuff to do cases with reasonable time and cost.
So a breakthrough with a 10ga FH, is putting 10 gauge
basecups from plastic cases onto 50cal Russian brass to
make a 4.05" long 10ga. I expand case using my shellholder
on original rim, put in bushing for shotgun primer, which
fires off RE17, the turn case and rim a little, and slip
on basecup with epoxy inside. Then take a 200 dollar heavy
barrel NEF 10ga, and deepen chamber like mine is.
Here is picture with one beside a 12ga FH. The 12ga FH holds
max load of about 330 gr ball powder below a slug,
and the 10ga FH holds 420gr. I'm getting things set
to get a bunch of cases to do this. Progress.
Now anyone wanting any of my cases for their collection
I have a package of them all. Contact me.. ...Ed
