I have an AR15 with a Burris XTR-14. I have it sighted in at 200 yards. When I try to shoot out at 500 yards, it seems to be all over the place(8 inch group). But I can shoot a 2" group at 200 yards and make the same hole bigger at 100 yards. I was shooting 62gr. M855 and had the rifle rested on a sandbag. What is it that I am doing wrong? I'm tempted to pay someone to teach me precision shooting.
Here are the specs of the rifle.
YHM 16" chrome lined barrel (1:7 twist)
Phantom flash
JP bolt and carrier
Burris XTR-14 scope with 1000yard recticle
magpul prs stock
jewel 2 adjustable 2 stage
