Don't know about the .30-30; it doesn't look optimal. It looks short, like a pistol bullet. How far is the bullet pressed into the cartridge?The 7.62x39 that people say the .30-30 is equal to in energy has a proper spitzer boat tail bullet. Fired from an AK it is still supersonic at 400 yards. The iron sight on the AK is adjustable up to 800 meters; with the AKM they increased it to 1000 meters. I wonder what they were hoping to hit at one kilometer with an AK...
