The American 30 that Ritch designed is a bit taller in the shoulder than the 30 Herrett built on the 30-30 you remember. We do it on a 6.8 case and it shoots very well. They've killed a couple mule deer at 300+ with it. I shot it late last week. I'll start a thread on it tomorrow as I've been working on 22-NXS data today. It is right on the heals of the 30 Rem AR and is out running a 24" 30-30 out of my 16" barrel on my AR by 100-150 FPS..
