Has anyone made a 6.8-7.62x39?
I have seen posts on a 270x39 improved but anyone have info on a 6.8-7.62x39 unimproved? Seems like an interesting option for AK shooters who want 6.8 SPC performance on a barrel swap.

Fat_AlbertRan the numbers throught LOAD FROM A DISK and a 6.8 X 7.62X39 came in at 33.3 gr of H2O. A 270x308 is 54 and a 270 JDJ (.277 x 225 Win ) is 43 gr H2O. Going with the 357 Max case and useing the 270 JDJ neck and shoulder it is 29.5 of H2O
