1/2in steel was placed at 300 yds. Indeed I am shooting a little bit low, I didn't know this at first. The next time I, just put the mil dot at the top of the target instead of in the center of the target. In fact, I think I've also checked my 50-yard zero again and I've made further adjustments since.... You get the idea. Either way I'm getting rounds on target and if that was a zombie down there he wouldn't be happy.

Rifle was sighted in @ 50 yards. Mike Adams talks about this in his survival guide. It may be a little confusing for you to understand, so here's an article that helps explain it.
