One of my biggest pet peeves is when optics makers show you this zoomed in view of their reticles and you get the idea that this thing looks giant and easy to use and then you get the thing in person and go "Well I can't see that chevron tip at all." (Primary Arms ACSS reticle at 1-3x is this way for me) What would help this is if they put their reticle against a known target size at a known distance and showed me that. Since very few optics makers seem to do this I thought "Well ok I guess I'll do it then."

I was inspired by this page that C-More has on their website:
https://cmore.com/DotSize

Which is absolutely excellent resource that I link to anytime someone says they need a 2 MOA dot to be precise on a pistol; look if you prefer the 2 MOA dot by all means go buck wild but if you can't be precise with a 6 MOA dot inside of 25 yards it's you not the dot.

Anyway here's a bunch of pictures of reticles at different distances for you to reference if you are curious. I intend to do this with more of my optics over the next few months. I don't know if I should put this post here or in the rifles section or somewhere else because I intend to do this with my magnified optics as well at some point. If you'd like to do it with your optics as well please do.

Notes:

My range has separate rifle and pistol ranges with the pistol range being able to stand anywhere inside of 25 yards; I did not go to the pistol range that day but I would like to take pictures of the reticles against the target at pistol distances as well at some point (Maybe 5, 10, 15, and 20 yards? I don't know yet)
rifle range has fixed target berms at 25, 100 and 200 yards so that's where I put my targets
My rifle range has fixed target berms at 25, 100 and 200 yards so that's where I put my targets; sorry I can't do 50 yards.
Target is a paper USPSA Target
I used my camera at 2x zoom for all pictures
This is intended to show you how large the reticle looks relative to a target you are familiar with, not be a 100% accurate representation of what the sight picture looks like if you were behind the gun; hence why I was ok with 2x zoom on camera
Pictures were taken with a Pixel 3A phone so obviously it's not great but it gives you the idea, if you want to pony up the dough to buy me a camera or loan me a better camera I'd be happy to take them all again
It's hard to get the white balance perfect relative to the dot brightness so that the dot looks crisp in the pictures so forgive me is some of these are a bit bloomy or too dim it was really hard to tell on the range while looking at my 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 dot and the 2 MOA dot only seemed redundant with the 507c so I didn't see the point.


I'm not intending to show bias towards Holosun it's just what I brought with me.

The target used across all pictures:
57882



2 MOA Dot Only:

57894

57895

57896




2 MOA Dot w 32 MOA Ring:

57891

57892

57893



32 MOA Ring Only:

57883

57880

57881



2 MOA Dot w 65 MOA Ring:

57888

57889

57890



8 MOA Ring:

57884

57885

57886

57887




Observations

The 65 MOA ring is almost the same size as the width of the USPSA target
At 100 yards the 65 MOA is about twice the size of the height of the target which makes sense because 65 MOA is just shy of the 68 MOA EoTech uses which is designed to be the height of the average man.
At 25 yards the 32 MOA ring is almost the same size as the C zone of the USPSA target. GJM is an advocate for using just the ring and this picture kind of "prooves" that out because inside of 25 yards the 32 MOA ring is small enough you should have zero issues making accurate hits.
At 100 yards the 32 MOA ring is about the same size as the target is long suggesting you should still be able to get decent enough hits even out to 100 yards if you just center your target in the ring and line it up with the top & bottom of the ring.
At 25 yards the 8 MOA ring is a bit larger than the A-zone of the headbox of a USPSA target but because it's a ring it's totally doable
The 8 MOA ring is almost the exact same size as the target is wide at 200 yards which is why I took a picture with it on target then then just to the right of target. I think you could make your shots with this at 200 yards even if it wouldn't be quite as easy as it would be with the 2 MOA dot so my previous assertion that the 8 MOA ring is great for PCCs holds true and I'd go so far as to say the 8 MOA ring is still pretty good for a rifle as long as you are only making occasional 200 yards shots on larger targets; if you are going to shoot rabbits at 200 yards this 8 MOA ring might not be for you.




Questions for you:
Was this useful/helpful/informative? Or was it a waste of time?
Do you want me to do this with more reticles and these reticles at pistol distances?

This is great info.

What Stoeger would say, is except zeroing and on a very unusual shot, if you are shooting the dot and not a streak of red, you are shooting too slow.

I actually just bought an 8 moa holosun based on the OPs recommendation to experiment with. I'm enjoying the 32 moa ring only on my v1 508t. Looking forward to a more precise ring and the ability to replace batteries easily.
I hope it works out. If not I'll have a holosun v2 407co for sale in the next few months, lol.

Honestly I like it so much that my only complaint is I wish they made it in their 509 or 403 series of optics that are are fully enclosed which would give me a little more piece of mind for using it on a rifle. As I said above it's going to be hard to use to make shots past 200 yards with it but for a rifle you intend to primarily be CQB I think it'd worth really well.

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.

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.
