I’ve wanted to do this for a long time, as many people have been talking about dot tracking in open guns and how to tune a flat shooting gun. I thought I’d try to take high-speed video of the dot in my open gun while shooting various loads of .38 Super Comp that i’ve pre-loaded. To see how the dot jumps and settles back into view. The dream pattern, is for the dot to jump straight up without leaving the lens, and settling back down in the middle. As you can see from the video, that’s definitely not what I see. My dot goes up to 12 o’clock, drives all the way down to 6 o’clock, then back to 12 and settling in the middle.
I tested the following loads :
- 115gr Montana Gold CMJ, 11.0gr N105
- 115gr Montana Gold CMJ, 11.2gr N105
- 115gr Montana Gold CMJ, 11.3gr N105
- 115gr Montana Gold CMJ, 11.5gr N105
- 124gr Montana Gold CMJ, 10.0gr N105
I don’t see any noticeable difference in the dot movement between all the loads except feeling a "softer" recoil in the 124gr CMJ loads.
Caveat: I had to shoot in a slightly weird stance because I had to position the scope in front of my Casio Exlim FH100 camera to align it properly. That definitely affected my recoil management capabilities.
I’ve also tried shooting at a man-sized target at 200yards and was amazed at how accurate this gun was. That’s in the bonus section at the end of the video.
