This 5 shot group measured 1.64", or 3.14 MOA, and was shot at 50 yards also using the Herter's 62 gr HP steel cased ammo. This was shot with the DMS-1 set to 4x power. As I mentioned on the previous page, this string with the same ammo yielded notably different results. However, if you look at the target, you will see that basically one of the shots is responsible for increasing the group size by approximately 1 MOA. Now....this could have been me or it could have been the ammo. I checked my notes and I did not call this shot to the right so I'm going with the ammo for now. Again, it is steel cased Russian and a group size of 3+ MOA is typical based on prior experience shooting this kind of ammo in other AR-15 rifles. Some ARs like it better than do others....and I would say my Eagle Arms EA-15 favors it better than some.
This 5 shot group measured 0.47", or 1.80 MOA, and was shot at 25 yards also using the Herter's 62 gr HP steel cased ammo. This was shot with the DMS-1 set to 4x power. This group tends to support the indication that this particular Herter's ammo will group in the 2 MOA area, most of the time, using my EA-15. If you were wondering, there are three shots sharing the upper hole and two sharing the lower.
This 5 shot group measured 0.48", or 1.85 MOA, and was also shot at 25 yards using the same Herter's 62 gr HP steel cased ammo. This was shot with the DMS-1 set to 1x power. With the difference in vertical offset being less than the bullet width, compared to the previous 25 yard group shot at 4x power, I would need better ammo to determine if there was any significant POI shift when switching between maximum and minimum power settings. Using the steel cased Russian ammo, I would say there is no discernable difference.
This 5 shot group measured 0.47", or 1.83 MOA, and was shot at 25 yards using the Fiocchi 55 gr FMJ boat tail ammo. This was shot with the DMS-1 set to 1x power.
This 5 shot group measured 0.48", or 1.86 MOA, and was shot at 25 yards using the Fiocchi 55 gr FMJ boat tail ammo. This was shot with the DMS-1 set to 4x power.
Hold on a second.....did you notice the last two groups shot at 25 yards? Both were with the Fiocchi 55 gr FMJ boat tail ammo but one was at 1x power while the second was at 4x power. Notice the big difference in the vertical offset from the center of the group to the center of the bullseye? I don't like that one at all. It would seem that changing power shifted the POI appreciably. That didn't occur when I shifted it while shooting the Herter's ammo but it sure appears to have done so here. Hmmm......this certainly screams for some more testing.
One thing will mention.....the alleged 1 MOA dot in the DMS-1 is NOT a 1 MOA dot. It is quite a bit larger. When I was shooting at 25 yards, the dot in the reticle was covering the entire 1" target. This means the dot in the donut of the Millet DMS-1 it is right at a 4 MOA dot.
So there you have it. Certainly an interesting day at the range. It would seem that we are seeing some POI shift when changing powers albeit not consistently. Perhaps the thump it received which took out the illumination caused more than just that issue. I typically leave the scope set to 4x and shoot it without changing it. I'll have to run a few more rounds through the EA-15 to be certain. When I do, I'll update this review with whatever my finds are at that time.
