What are you trying to figure out on the 77 SMK, I shoot 10-14k of them a year, they are a very good shooting bullet out of a 1:8, 1:7.7, 1:7 or 1:6.5 twist barrel and some 1:9 twist will shoot them well too. The universal load for service rifle use is 24 grains of R15, 24 grains of Varget, or 23.2 grains of IMR8208XBR assuming a Wylde chamber.
