Range Report with GAP Precison Rifle.

I fired 7 5 shot groups after getting the scope sighted in and after figuring out how to set up the zero stop. My friend fired 2 5 shot groups for me. He beat me with my own gun and got the .59 5 shot group. Ammo was Federal match with 168 grain Sierra Bullets.

    He was playing with some loads on his 5.56 that I assembled for him. It did really well with a new load I am trying.

    The load data is on the pic. This load has shot well in all of my guns. My friends gun has a 1/9 twist barrel and it still shot it well.

Anyway it was a great day at the range. I got the side mounted red dot on my rifle sighted in at 25 yards. The back up irons at 50 and the scope was zeroed at 100. The muzzle brake took a lot of the recoil and muzzle flip away and the gun was easy to keep on target. It also was not as loud and did not give me a headache like it did when I had it installed on my previous .308 carbine. On the rifle it is further out there from my head and the concussion did not affect me like it used to on the carbine.

Both me and my friend had issues with mirage and eye fatigue. When we looked through the scopes at first everything was shape and after a while the target and cross hairs would get blurry until we rested our eyes. What causes this? Thanks in advance. I played with the parallax adjustment while shooting. I thought it might be from the heat coming off the barrel in front of the scope. It was 28 degrees out.

You may have to back off the power setting at 100, you may not be able to adjust the parallax at 22x and at 100. The mirage off the barrel will be noticable with higher pwer and more so when it’s colder. Try running it back to 15x or less and the parallax adj should help. You may want to look into fitting a mirage band as used on some match guns I think sig and Steyr use one.

Remember also-that may cause some vertical string(along with other things) Mirage-makes the target appear higher than it is, track the last shots, all adds up-mirage off barrel, breathing, etc etc

I had some bad mirage last weekend with the 6.8 and using a 3.5-15x NF for testing loads
