Jack,

Thanks for the thread... awesome write-up!

I too, would like to delve further into the Topic of POI Shift, especially concerning Zero's and First Round Hit Probably. I had briefly read about Bryan Litz's WEZ Analysis, but haven't really finished it all yet.

I'm def. curious as to how an AR15/AR10 system stacks up against Bolt Guns such as AI/Sako TRG/M24/M40 etc. concerning Shift.
