Thanks for the encouraging words guys.
Erik has somewhat of a different perspective on distance than most do.
My son has been shooting a MOA handgun since he was 9 years old (14" 260 Rem MOA Maximum, 260 grain NBT's).
The first week he started shooting a SP, by the 3rd day he was a consistently hitting a sillywet ram at 500 meters and has been in several comps at 1,000 yards, using the MOA and XP-100's.
All of that being said, shooting a live animal under field conditions is different than off of the bench or steel from the prone position.
I am very proud of him.
His first antelope kill was a doe last year and he used one of my XP's (6.5-284) and made a 260 yard shot from the prone position (1-shot downed the doe permanently).
He was happy for his first buck that the range was an easier shot, also using the Harris bi-pod.
