I've been reading up on zeroing the M1a/M14. There's lots of good info out there, including the writings of Scott Duff. I do have two questions.
To adjust for windage involves moving the front sight .008 inches/MOA. That's about the width of two human hairs, and it's not like I've got any to spare. Is there some technique or does one just eyeball it and hope for the best?
The standard 25m zeroing target for the M14 is often referred to as a "Canadian Bull". Why was it called that?
