12ga cartridge 2 others and I developed. It is
an upgrade of the old paradox gun concept.
Only we solved the problem of weak cases, and we
made cases by putting 12ga rims on BMG brass.
That allows many reloads and much more power
due to case strength.Other guys chamber theirs in
bid Borchardt falling block actions and I put heavy barrel and stock on a Savage 210 bolt action for mine.
I havw gotten as high as 14,000 ft lbs,and other
2 guys can get more with their guns.Here is picture
of our case next to a regular 12ga case, which by the
way can be fired in our chambers also. In the spirit
of the intent of this forum, this is one of the best
uses of "milsurp' brass bmg case.Ed
