Another day at the range, this time with a new toy:
That’s a Sightmark 5x slide-to-side magnifier to go with my Sightmark holographic sight.
A magnifier, like any scope, has a quality called “eye relief”. Position your eye too far away from the lense, and the result looks like this:
Get too close, and you see this:
Positioned correctly, you see this:
That’s the front sight post partially obscuring the view. One of the disadvantages of this arrangement.
The second disadvantage is, this isn’t actually what I see when I look through the magnifier. When I actually put my eye to it instead of the camera, the red holograph in the center is distorted. I don’t mean the fairly mild lens flare seen here. I mean the dot looks like somebody smeared it upward with his thumb.
The third disadvantage is that my shooting was actually worse than when I shot without it.
Crap! Out of 30 shots fired, five to each target, I can’t even swear I hit the board more than 10 times at 100m, let alone put my shots on the target at which I was actually shooting!
I need to bring this back in to 50m and see what happens.
American Eagle XM855F 62Gr FMJ-BT Ball:
Please ignore the .45ACP you’ll see scattered around the targets
Black Hills 55Gr FMJ “Remanufactured Seconds”:
Don’t pay attention to the XM856 in the upper left corner. I did fire that ammo at this target, but it didn’t hit it, nor did it hit anywhere else on the board. So I tried again with the Black Hills.
Black Hills 60Gr. Soft Point:
Again, pay no attention to the “Fiocchi” in the upper right. I ran out of that ammo trying to hit the board at 100m.
PMC Precision 75Gr. Match:
Reliably the tightest group, but the zero is way off from where it was previously. Could the quick-detach be catching up to me? Could the magnifier be moving the zero?
Sellier & Bellot 55Gr. SP:
I seem to be missing one (the whole in the right not belonging to me).
Tul Ammo 55Gr. FMJ:
With the exception of the shot that went wide on the left, this wasn’t a bad group. I actually haven’t been disappointed with the performance of the ultra-cheap Russian ammo. Too bad the steel cases are so hard on the rifle.
Okay, let’s do a side-by-side comparison. Picture sizes have been approximately adjusted to match target sizes.
Black Hills Seconds:
Black Hills SP:
Sellier & Bellot:
My off-hand estimation is that the magnifier has made me slightly more consistent at 50m, although that could be a marginal improvement in technique or just day-to-day variation. But dagnabit, I bought a magnifier to make me more consistent at 100m!
