Just bought a 22lr Savage bolt action with Picatinny rail. Was going to get a 4x scope of some kind, but I shoot mainly at gongs and softballs at 25-50 yards. I started wondering if anybody shoots a 22lr rifle at that distance with a non-magnifying red dot sight? And what does 2 MOA mean when it describes a red dot sight?
Red Dot on a 22lr plinker?

MOA red dot sizes are the size of the dot. So the smaller the MOA number, the smaller the dot is and larger MOA number, the larger dot size. So a 6 MOA dot is going to cover more of the target and a 2 MOA is going to cover less of the target. 2 MOA will allow you to shoot with more precision.

I use Red Dots on all manor of long guns.
2 MOA, means the dot is 2" at 100 yards, so a 1/4 that distance it will be 1/2", you'll be able to see your target just fine! But it takes 4 times as many clicks to move one inch during adjustment!

cheap red dots on a 22s are fun... have a 20 dollar one on a AR15 22.. everyone enjoys it

I have a red dot on my .22 LR AR-15. Fun to shoot quickly, make tin cans dance, etc. My bolt action .22 LRs are either peep sights or scopes. Shoot more for accuracy and tighter groups with those.
Just be sure to get one with adjustable dot light intensity. The red dot is difficult to see in Bright sunlight.

OP
Thanks for the reinforcement. I have a red/green Truglo on a side angle rail of my M&P 15-22. I don't want to order any scopes until post Xmas shipping settles down, so will take the red dot off the 15-22 and move it to the Savage B22 just for break in purposes.
You guys have me thinking!
Bought an AR two weeks ago that came with a red dot. I took it off and replaced it with a LPVO scope and was wondering what to do with the red dot.
I have a tricked out 10/22 that has become the resident welfare case. Literally have not shot it since I bought my 17 HMR 3 years ago.
The red dot may breathe some new life into the gun.
Thanks for the idea!!

I've tried a dot on several plinkers that I didn't want to scope. I ended up going with peep sights instead for a bit more precision at the closer ranges that they are used at.
But if my eyes get much worse I might go back to the RDS.

Whoever told you there'd be no math here, lied!
MOA refers to minute of angle.
There are 360 degrees in a circle, 60 minutes in a degree and 60 seconds in a minute. The formula for the circumference of a circle is Pi x radius x 2 (Pi x Diameter).
A circle with a radius of 100 yards (distance to target) has a circumference of 628.319 yards, which equals 1884.956 feet or 22619.467 inches.
1 degree of angle at that distance => 22619.467 inches/360 degrees = 62.832 inches
1 minute of angle (MOA) at that distance => 62.832 incles/60 minutes = 1.0472 inches
MOA's are obviously linear, so 1 MOA @ 50 yds is half that size (.5236") and 1 MOA at 400 yds is 4X that size (4.1888").
Remember, knowledge is the greatest gift.

That's a good approximation. It may help those who slept through geometry class just what MOA means and where the numbers come from.

I saw "Red Dot" thought 'powder' and immediately jumped to "this ammo shortage is really getting bad if they are trying to reload rimfires".

Thanks for explaining this to us. When I was working with land legal descriptions I had to work with degrees and minutes in order to establish the bearings for each line in a legal description.
