Most ammo we get for the AR 15 around here is 55 grain which is optimum for the 1:9 barrel twist. I don't see any 77 grain around much, if at all. Unless of course you reload. I think the people at Schmeisser took this into consideration when they went for the 1:9 twist rate. (German smart!)
The 1/7 is good if you want your bullet to break apart when it hits its target causing maximum destruction of the object it hits. Good for military application, right?
I like the 1/9 twist myself. The Zombie will still fall down. The rifle looks real nice and I would love to try this one out.
