For those like me who are math challenged.
MOA Clicks
5/8 1
1 1/4 2
1 7/8 3
2 1/2 4
3 1/8 5
3 3/4 6
4 3/8 7
5 8
The table repeats from here.
Anyone correct me if I'm wrong, I beleive this works for front and rear sights.
The fly in the ointment here is that with differnt barrel lengths this table isn't exact.
How about putting column headers on that? I assume that the right column is clicks? Is this for the front sight, rear sight or both?
What barrel length is that table for? Did you get the info from TS or calc it yourself?
We checked the T-100s on the 'carbine" length 10/22s, by shooting, adjusting and measuring.
It is 1 moa per click on the carbines (18"). This goes with the .8 moa per click that Tech-Sights says for the "rifle" length (21")
This is easier to remember.
By the way.
I made adjustments with a T-200, using the front, to zero. Then, to "save" the front elevation for later, adjusted the rear to the bottom, counting clicks, then lowered the front the same number of clicks. The POI was the same, so I would say that front and rear are the same ;)
Just for fun, I zeroed with one shot, confirmed with one shot, reconfirmed with one shot....The fella that had that rifle was concerned because he only had 13 rounds of ammo to zero with. I told him it should be "plenty".......Rifleman stuff is fun :P ;D
Nice job guys! This is good stuff for the trail! JB
This is really good info.
However, I installed an A2 front post in my Tech Sight. I liked the idea of the front sight post always presenting a flat face towards my eye. Of course it only has four clicks rather than five. I suppose, since the thread pitch is obviously the same, that means that each click actually changes the elevation by 5/4 of the distance as compared to the A1 sight, meaning that the distance of each click is 1.25 times the distances shown.
I guess I need to develop a table showing the different values of clicks for my front and rear sights. The rear sight clicks should be the same as posted. The front clicks will represent 1.25 more.
1.25 MOA for an A2 type post is correct.
Gentlemens [sic], there are so many variables involved in this that don't you think the best strategy, instead of trying to hand each shooter a fish tailored to his rifle/sight combo, we simply teach him how to fish?
(Not trying to pour any cold water on this thread. Continue to work out all the permutations. But be aware that it may help the shooter better if you tell him to figure it out - cause he's the one who needs to know how to do it. Otherwise, you give him the number, and he doesn't have the chance to learn how to do it himself...)
here are some flies for you ;D
go to the range and fish
teach others to fish too 8)

The technique I've developed is to forget that the rear aperture-flip is there - I just use the long-range one. I make my windage adjustments with the rear sight, and the elevation adjustments with the front. Once you've doped out the different adjustments for each position, and noted them down, then it's just a matter of dialing them in as you move through the different stages.
I know this is gamesmanship, but if you're shooting for a numerical score, then it's a game, right?
But it all boils down to knowing your rifle.

Knowing the dope on your rifle and using it isn't gamesmanship - that's critical to shooting at distances where bullet drop starts to exceed 4 MOA. Most people who sit behind a scoped rifle professionally are also going to have a notebook next to them with the doping written at every 25 yard interval.
Had to adjust my TS-200 sights on my Ruger 10/22. Required reading the instructions. Being that the instuctions said approximately 5/8 inch per 100 yard each click, it complicated the mental calculations for the 25 meters I was shooting since it is not 1 inch per 100 yards etc.
Long story short.
100 yards = 300 ft 25 meters = 82 ft 82/300=.2733 factor at 25 meters
Convert 5/8" to decimal = .625" each click per 100 yds.
.625" x .2733 = .1708" per click at 25 meters
Sight ajustment for 3/4" on 25 meter target - convert to decimal, .75"/.1708" @ 25 meters = 4.4 clicks
Handy and less stress if you have a calculator and you can use the magic number .1708" per click @ 25 meters after you determine that you have to move POI 2.5 inches at 25 meters - now quick, how many clicks is that?
2.5" / .1708" = 14.6 Clicks
Maybe some superfluous decimal places in the above calculations - make the magic number .171 or .17 for clicks on TS-200 sights on a Ruger 10/22 at 25 meters.
I actually shot a "box" pattern with mine abd it comes out to exactly .8 MPOA per click for the 22" barrel.
We have been using 1 moa = 1 click on the carbines. Seems pretty close. These are the T100's
