How do you plan on dealing with extractor lip thickness on a .125" bolt face depth? That is the real challenge.
Where does the 37% more material come in and still maintain the correct extractor ramp angle?
On AR10 bolts, they can use .125" depth because the extractor is much wider at .312", whereas AR15 extractors are .240" wide.
My East German steel case 7.62x39 ammo ranges from .443" to .445".
Blank cartridge head diameter is .444".
