Reference Material: Red Dot Reticles Relative to Targets @ various distances

[psalms144.1]

That's great stuff right there - thanks for taking the time to take those photos and post them!

Those photos point out one big advantage of the dot-ring reticle: if the contrast between the dot and target is minimal, the likelihood is that the ring overlaps at least something with good contrast between the ring and the background.

Good info.

I’m glad I’m not the only one who finds some of these BDC rds sights nearly useless. Even with a 3x magnifier, their usefulness is somewhat questionable.

Very informative - thank you for taking the time to put this together - lot of effort put into this!

Thank you especially for the 8moa ring. I was wondering how it would look. I think I want to try one out.

Thanks, just put a 407co v2 on backorder - based on your pictures it looks like something I would like but didn't think so prior to seeing your pics. Great work!

I went back to the range to take shots at "pistol" distances. The pistol range is an open range where you can stand anywhere 25 yards or closer. I was debating on doing pictures every 5 yards but that seemed excessive so I did pictures at 25 yards, 15 yards, and 7 yards just to give you an idea. For the optics where I already had a picture at 25 yards I didn't take a new one. I tried to take some pictures of the RMRs at 100 and 200 yards but for some reason those turned out very blurry for the most part so I'm posting the ones where it's somewhat legible but I couldn't find a good one of the 3.25 MOA dot at 200 yards, sorry. Also the RMRs are mounded on a pistol and I didn't want to remove the dot just to take pictures so I found it was much easier to lie the pistol down on it's side than try and hold the pistol in one hand and the camera in another so if you're looking at it thinking "Why is this RMR on it's side?" that's why.


As before:

• Target is a paper USPSA Target
• I used my camera at 2x zoom for all pictures
• Pictures were taken with a Pixel 3A phone

The optics used were:

• Holosun 407CO with the 8 MOA ring reticle
• Holosun 507c pictures taken with 2 MOA Dot only, 32 MOA ring only and 2 MOA dot + 32 MOA ring at all distances
• Holosun 503CU with is a 2 MOA dot + 65 MOA ring; this model does not let you do ring only so no pictures of just the 65 MOA ring
• Trijicon RMR Type 2 6.5 MOA dot
• Trijicon RMR Type 1 3.25 MOA dot

Observations

• At 15 yards the 32 MOA ring was about the same width as the A zone and headbox of the target
• At 7 yards the 65 MOA ring was about the same size as he headbox and A zone of the target.
• The 2 MOA dot and 3.25 MOA dot were not noticably different in size to my eye until I put it on a 100+ yard target.
• The 6.5 MOA dot somehow "feels" noticably smaller than the 8 MOA ring. This is likely do to the way in which the area of a circle grows in relation to the diameter.
• I "feel" like hits at 200 yards would be harder with the 6.5 MOA dot than the 8 MOA ring. This has no basis in any actual fact as I have not tested it so take this with a huge grain of salt.

Correction; I fudged up that caption, fixing it that picture is actually at 100 yards:

Very cool. Thank you!
