How bout some pics of those M1A's in action!
Below, my original M1A before I upgraded to a NM. Here my buddy spots while while I give a 2MOA target a run for it's money at the 800M range.
Unfortunately the ammo was only 4 MOA. What would my
theoritical hit percentage be? Better know that in the field.

That sh!t eating grin only comes when you nail the 4MOA 600M plates with a M1A NM. Tell me again how big those targets are?

Mrs. TG shoots the NM in the fuzzy back drop of NM's highest pk: Wheeler Pk at about 13,000'

And finally, from prone, we clear a row (set 7-11) of 500M rams at the NRA's Whittington Center at an Appleseed Shoot. Note that only the fixed rams remain.
Then we nail the 1000M White Buffalo in the distant center. It takes about 4 seconds to hear the "to-wock" of the steel. The entire buff is 6x8 MOA. So how big is it at 1000M?
Do you know the come ups between 500M and 1000M (how many clicks)? You should.

(note:we were only trying to hit the buff to check the come ups, not the 2' black plate)
Also, it ain't the same for NATO spec and match.

Out on BLM land near Las Cruces. A 4 MOA target at 500M. The padded shooting jacket pretty much eliminates a need for a shooting pad, even on rough terrain.
The target is near the white strip of sandy soil across the arroyo.
