I cleaned the bolt, chamber and barrel and got only 1 failure to extract at the match.
My son and I shot the match yesterday, he with the 5200, me with a scoped Remington 513T. I mounted a Bausch and Lomb 6-24X scope on the 5200 and a Bushnell 3200 Elite 10X on the Remington.
It was pretty cold (low 30's) for these parts and it seemed to have affected the zero of the rifles. Winds were light and variable. We had to re-zero the rifles a bit to get them back on target. The match was shot off a sand bag front rest, no (except for your hand) rear rest At 50 yards.
Here is my son's warm up target. Unfortunately we turned in our official targets.
The bullseyes on the left and right were to warm up and re-zero the rifle. The center group was a 4 shot (.403") group to confirm the re-zero. You can see some of my son's match stick hits as he settled in on the target. He was using the CMP black box practice ammo.
I'm kinda interested in what honest-to-God target ammo would do.
