I cast, checked, and powder-coated some 311316s and have aspirations of seeing how fast the can be made to go with accuracy. Sort of a ".30 Carbine improved", maybe +150-200 fps. With 115 grains of bullet.
Powder of choice according to Quickload seems to be H110/WW296 (big shocker there), 100% load density giving near maximum pressure and velocity. Almost 2300 fps predicted.
From my 7" ROT AR barrel that will be about 236,000 RPM.
Is this idea doomed, or has anyone here tried something like this?
