Thank you both very much! This is exactly what I was looking for.
Here's why...
This is the Ferret .50; a top-end attachment to an AR15 lower. Excellent quality, and great customer service from Dave Moore of Spider Firearms. I highly recommend him and his product.
My problem is that the upper came with a 30 minute rail. Thus, to begin zeroing on an optically centered scope, you have to come down 30 minutes at the start. NONE of my scopes have enough adjustment to do this right now.
So, at the ranges available for zeroing here that will even let me fire a .50, I can use these tables to obtain zeroing data by comparing point of impact to the tables.
Thanks again!
