diyj98, I can't argue that the fact .5MOA at 100 is not the same as 500. Cause I really have never had a .5MOA rifle. Love too have one, but just isn't in the cards. My 300RUM custom is close but usually always gets a flyer in a 5 shot group. It gets 0.7MOA average at 100 yards. Moving out to 500 yards. Best I can do is hold a 8" group.
