Walking around the local show awhile back, I came across a vendor demoing an optics configuration identical to mine: a Sightmark holographic sight with a 5x magnifier. Except the demo had none of the smearing that mine had; the reticle was in perfect focus. That was all the motivation I needed to call Sightmark and gently insist that they repair either or both of the optics, as needed.
They did, and I was quite happy with the result:
Now that’s the sight picture I wanted.
So, it was back to the range. But I made another change in my technique. I started using a sling, specifically using a “hasty sling” to help brace the rifle. I also had some new ammunition to try out.
Lake City FMJ1F 55gr.:
This is the tightest group I’ve ever shot. Unfortunately, I was unable to repeat it:
This group was somewhat later. My theory is that as the barrel of the rifle heats up, the pressure of the sling on the front of the hand guards starts to throw off the precision. The alternative possibility is that the sling just adds another variable that I have to struggle with to keep consistent.
Not the worst ammo I’ve ever shot, but not the best either. I took it out to 100m:
As bad as this is, it’s the best I’ve ever done at 100m. What I don’t understand is how a 2 inch group at 50m became a 10 inch group at 100m. I would think that simple geometry would give me a 4 inch group. I’m going to try without the sling next time and see what happens.
