Dot MOA for Red Dot Optic Use On Double Rifle?

What is the consensus on sizing Dot MOA for Red Dot Optic use on a double rifle?

Thank you.

My trijcon has a 1 moa dot and the kahles has a 2 or 3 MOA dot. (Dont remember for sure) Allows for much more precise aiming than the irons.

I have a Trijicon 3.25 on my 500ne. But I mainly shoot irons.

Following

Not a double but I use a 1MOA RMR on my 416 Rigby.

While I don't have a double, my general standard is that I want 3MOA or less on a dot, and preferably the selectable "circle dot" style of reticle.

This may be worth reading through….

Red Dot and RMR Sights for Dangerous Game Rifles

I have been contributing information concerning Red Dot and RMR Sights for Dangerous Game Rifles on a couple of other threads that some AH members may have missed. I figure that this information warrants its own thread, so here you go!

He beat me to it.... Highly recommend reading that article.

FYI - I have a 1 moa on my .470 and its perfect.

1 MOA on mine. As a side note, all of my professional work weapons (pistol/rifle/12ga LL platform and 40mm launchers) all run 1 MOA optics.

@Mark A Ouellette should be along shortly to drop the knowledge.

I prefer a smaller dot, around 2 to 2.5 MOA for rifle work without magnification. Gives me good hits out to 100 yards from sticks. I’m using an AimPoint T2.

I like 1 MOA, and IMO it seems a lot bigger than 1 MOA to me. I tried a 3.25 and it was way too big for me.

Hi @BeeMaa It seems the only time I'm far away from this forum is when I was taking a nap and missed out on the opportunity to buy that Heym Martini Express at a $10,000 discount! Sleeping on guard duty...

On a reflex sight commonly known as a red dot, the size of the dot will increase with the intensity of the illumination. On a sunny day the dot size required to be seen will be larger than at dawn, dusk, or a very overcast day. In fact, the only time my 1 MOA dots cover only 1 MOA of the target are during dawn, dusk, or a very overcast day.

On a defensive carry handgun with maximum practical range of 7 yards, a 3 or 6 MOA dot makes sense. On a hunting rifle that may be used for 100 yard shots, aim small with a 1 or 2 MOA dot because on an African afternoon, the dot will likely be 3 or more MOA just to see it against the sunlit background!

PS: I also I am going to try the Aimpoint H2 with its smallest 2 MOA dot on my trusty Heym 88B in .458 Win. Trijicon RMR and SRO dots flare into an egg shape for both my eyes. The Aimpoint dots on several H1's and my new H2 do not flare as much. In fact, the Aimpoint 2 MOA dot appears smaller than the flared Trijicon 1 MOA dots!

@Mark A Ouellette is our Dr of These type scopes. I would refer to his extensive experience and testing of each. For myself I use a Trijicon RMR 1.0 MOA after trying others but always coming back to this. Chris Kyle is correct “aim small miss small”. I want the smallest dot that I can still see…I have found I shoot my DRs much better

I agree with the 1 MOA sentiment. That’s what I selected.

I did attend the red dot seminar at DSC. It was hosted by Julius Fortuna from the double rifle society and featured a couple of PHs along with Graham Wright and someone from Trijicon. Julius really pushed the 3 MOA solution and the Trijicon guy agreed when I talked to him at the booth.

I still think 1 MOA works for me but it was interesting discussion.

Like I've previously alluded to, I still use red dots on my work pistol/rifle/shotgun/launcher platforms daily and will agree that the larger MOA (3+) are advantageous at CQB distances of say 21'/7 yards and in for rapid target acquisition with both eyes open, which is what is occurring during a charge or gunfight during an adrenaline dump. The advantage of a 1 MOA is being able to line up a shot a distance due to the smaller/finer dot. I took a bushbuck at just over seventy yards last trip with my double in 9.3x74r with a 1 MOA Trijicon RMR. At that distance a 3 would have completely covered the sight picture that I had through the brush. It's pro/con on size, if it's going to be dedicated to short distance then the larger MOA is advantageous for rapid target acquisition, but if the possibilities of distance are there smaller is better.

My preference is for a 2 to 3.5 MOA red dot. I find a 3.25 RMR type 2 is a great size for me and has worked out well for me in real world situations out to about 150 yards. Beyond that I would want to be using a scope.

I also use Noblex (Doctor Optic) they don't offer 1.0 MOA on the models I shoot, I typically opt for the 3.5 MOA option.

Here is what Trijicon has to say about dot size for their RMR sights, on their website:

1.0 MOA Dot​

The 1.0 MOA dot gives the user our smallest dot available in our Adjustable LED models. The fine dot allows for shooting more accurately at greater distances and is a great solution for long-range pistols, rifle, and carbine applications.

3.25 MOA Dot​

The 3.25 MOA dot is the most versatile and popular of all RMR dot sizes. The dot is small enough to allow accurate shooting at range while also being big enough to locate quickly.

6.5 MOA Dot​

The 6.5 MOA dot gives the user the biggest dot available in Adjustable LED-operated models. The bigger dot size gives the user the ability to locate the dot quickly, which is ideal for close-quarter engagements, and is also a great solution for those with poor vision.

I think,
the 2 moa is a great choice for hunting. I always chose her for hunt. Until I got to know this type of scope better, I thought it could be shot at distances of 150m. As I used them for a long time, I concluded that the points are still made for shooting up to 100m. It happened to me that I was shooting at a jackal 130m away and I missed it (2 moa). Of course, the effective distance depends on the size of the animal, but... I adjusted a lot of points on the shooting range and performed various experiments. If you shoot at a target at 100m/100yds, you will see how much larger the group is than with an optical scope. I had the best groups at 100m when I aimed to use the top of the dot as the center of the aim. Then the hits were close to each other. I can recommend that to others from my humble experience. Adjust the scope at 100m/yds to the top of the dot, and at shorter distances when shooting quickly use the center of the dot. Something else is important. With lower-quality manufacturers, you should choose a smaller dot, because when pulling the sight to one side, its edges spill. If, for example, 3.5 moa is selected, it is impossible to hit a deer at 100 m (it is possible, but it is significantly more difficult).
For the weapon you're talking about, I don't think the size of the dot is important, because it is most often used to shoot at up to 100m, and at large-bodied animals. I would still choose 2 moa in that case

I don’t have a double, but I do have a 1, 2 moa, 3.25 moa and 7 moa red dot of various manufacturers. I also have a number of scopes with the Leupold red dot on them. I have them on pistols, shotguns, semi-auto carbines, and hunting rifles and have used them a lot including doing a number of courses with them.

Any size red dot is much, much faster than iron sights or a reticle. It’s not even close. As others have said, there is no need for anything but a 1 moa or 2 moa red dot on a carbine or rife. I don’t think there is on a pistol either, but I can see the argument to be made there.

As far as blurry or oblong red dots, I have astigmatism and experience this two. The aimpoints are better than the Leupold delta point/trijicon RMR for this and a magnified optic is best of all. However, it makes no functional difference and is less noticeable on smaller dots.

For Doubles, I prefer the 1MOA RMR Type II. I have a RMR HD that is also 1MOA and whatever the circle thingy comes out to. I don’t love it, it just hangs out in its cute little black Trijicon box with sexy red latch…and while I like the battery tray on top, that’s about it, and do not like how it sits higher. The type II allows better cheek welding, and the 1MOA seems perfect.

I did briefly have and shot a Doctor 3moa, and I liked the optic, didn’t hate the dot size, it seemed to starburst less than the Trijicon when brightness increased, but would have liked it more if it were 1MOA I think.

I have several RMR and RMR-c on pistols in 3.25 and 6.5 MOA and like the 3.25 for its intended purpose on a self defense handgun.

Just my pennies worth:
I have a Chapuis with a 3moa Docter red dot which I love (despite having good eyesight) as it keeps POA crystal clear even when tracking/swinging through shady or dappled woodland. One slight downside is that the automatically adjusted dot brightness does so based on the brightness where you are not where the quarry is. So if you're in bright sun and what your aiming at is in dark connifers then it'll be harder to pick it out against your dot. Its not a big deal. The next issue is that if you have an open emmiter and it's raining then you can get water in it and then you're in trouble.

I do agree that while some red dots are better (less bad) at longer distances, it's not what they are designed for and not something they're good at. Fortunately the solution to the rain and the range is the same: quick detach pivot mounts. This way its easy to swap between a telescopic sight (1-4 times optic) and the red dot when the situation calls for it or the irons if your close and in the rain. 99% of the time I'm using the red dot - if I need more range then I use a bolt gun.
