I have a gentleman lined up to make my action!! The plan is to use one of his falling block actions, but scaled up to handle the big cartridge. Obviously it's a little expensive ($3000) but that honestly is NOT BAD considering a a BAT 50 bmg action is over that and considerably larger and definitely heavier. I cannot believe this is gonna happen. Almost brings a tear to my eye
