The rounds that I shot yesterday were 46 grains of 4046. Load data for the 9x56 is not very abundant. I have some load info from old reloading manuals. Powder choices include 3031, 4895, and 4350. That 6.6 lb rifle packs a pretty good wallup!
I made the bolt shroud peep sight for the rifle. I will need to work on fabricating a taller front sight. More fun stuff.
