    Think of a circle as it is divided into 360 degrees. Each degree is divided into 60 minutes. Each minute is divided into 60 seconds, but
    We will be talking about minutes of angle, so..A Minute of Angle is 1 MOA = 1/60th of a degree

  • John Fourteen Six Apr 12, 2011

    1 MOA = 1.047 inches at 100 yards or to just be cool about we just say 1 MOA = 1 inch. Most accurate long range scopes are set in quarter clicks, So for instance 4 clicks will move the center of impact 1 inch... make since? (4 clicks = 1 MOA)

  • John Fourteen Six Apr 12, 2011

    eighth clicks (8 clicks = 1 MOA) but less accurate short range scopes are sometimes set in half MOA clicks (2 clicks = 1 MOA) would be each click = 1/2 inch.

  • John Fourteen Six Apr 12, 2011

    Most accuracy testing is done at 100 yards, because it makes the math easier, and it is close enough to see the bullet holes through a spotting scope.
    So you will have to do the math on your settings at 25 yards. Hope this helps Fixya up.

Cannot get to the bull's eye. rifle shoots 2" to right of bull's eye. after two full turns left on windage - nothing happened. I',m ready to return to the store. Any help???


continue to adjust the wind-age. If your problem persists I would suggest turning both to a random point and re-start sighting the gun. If that does not fix the problem return the sight because this most likely means the wind-age is disconnected.

How do I adjust my scope on my Crossman bb/pellet rifle .177


Assuming the scope is ok, and the gun is ok, it must be the shooter, Not you but the stance, holding, bench rest, something is not consistent. If I was you, I would set up a big piece of cardboard at 15 yards, get the rifle on a beanbag or a bench rest, aim at a one inch spot in the center of the cardboard, shoot about 3 times, depending on where the pellet is hitting, move the adj knobs accordingly, do it again, 3 times, adj, as many times as it takes, get it centered, then, shoot it about 3 times at a clean plate, if it hits it's mark 3 times, then you can try it standing, and you should be able to build confidence in it so you know where it shoots, and won't be discouraged. Now if the rifle is bad, or the scope mounts loose, you will fight the thing all day and end up trashing it. I would blame the mounts first, then the scope, then the rust spot in the barrel, rare. If it is a break action rifle, you can set it up in a box with v's cut into it, look through the bore at the target, make sure it doesn't move, the scope should be looking at the same exact thing, if it isn't, something is wrong. You can set it up this way to start, and then fine tune it with pellets. Check it out, hope this helps.

How to reset to zero a Tasco RF3- 7X20 Scope? I am having prblems centering this scope Thank You


Making sure it is correctly fitted to the rifle, you Bore sight it. Best to put it into a vice using a thick piece of blanket to protect the rifle. Looking through the bore you line it up on an object about 10 to 20 meters away. Then you adjust the scope to fix the crosshairs on that same object. This will get you approximately on target. Depending on what a where you are going to shoot, assuming you are using a rimfire rifle, You then set up a target about 30 to 35 meters away. And adjust your scope to center on this target. That will give you dead aim at 30 meters and again at 90 meters, with only a slight variation in height in the middle.

I think formula in instructions for calculating actual clicks for non-100 yard distances is bogus. upside-down. very very wrong. you know what I mean or should I quote it? not your problem, it's GAMO's....


your wasting your time with them my friend, all they will say is,,,a 177 air rifle shooting over 100 yds?????
you are kidding!
dont bother reading up all the jen, just set out some targets at 5yds apart and shoot at them till you find out just what your rifle's bullet drop is, but at 100yds you may fine your shooting at the sky,,,,

How to set my bushnell scope 3-9x40 for 200 yards


The Bushnell 3-9X40 has been around for quite some time in several forms, but it is pretty standard to set it like any other scope.

With the gun resting solidly on sand bags or something like a Lead Sled, shoot at a target with a 1" grid on it. Those targets are a free download at http://targetz.com/, but you have to browse to find them. Targets No: 10049 or 10058 are both usable, if you can see a 1" aiming point with a 9 power scope at 200 yards.

With a known point of impact (POI) at 200 yards, you can move the POI to where you want it (inside the caps at the center of the scope, there are adjusting screws or slots). The norm is 1/4" per click (the adjuster can usually be felt to click) at 100 yards or four 1/4" clicks for an inch. At 200 yards, the adjustment will be twice what it is at 100 yards or 1/2" per click.

Make your adjustments, using the grid on the target to tell you how many inches it needs to move, and shoot the target again to confirm the adjustment is correct. It's pretty standard to shoot at least a three shot group to ensure the bullets are reasonably close to each other.

Another method is to set the POI at a certain number of inches high at 100 yards and assume it's right at 200 yards. If the mid range trajectory, for your cartridge, at 200 yards is X inches high at 100 yards, you can set your POI to that X inches high and be pretty close at 200 yards.

I can shoot my centerpoint scope on my .22 and it


When adjusting a scope just move a few clicks at the time, after every few clicks tap the scope with a screw driver handle. Fire 2 rounds for group tap and fire the third round it should be in line with the 2. Keep that up till on target. Let the gun sit till cold and re-fire for grouping, 2 rounds, wait then the third. To keep shooting round after round can get the reciver warm enough to wedge the scope in its bases, causing your problem.

How to sight scope in /what scope do i have ?


Real simple Scott.
You can 'Zero' your scope/rifle even if you don't have a laser bore-scope device.
All this is assuming that your used rifle has not had the barrel shot out and that the head-space is still within specs for that rifle. Have all this checked by a gunsmith first. You can dress up a piece of poop and it will be pretty, but still be poop. Make sure yours isn't to begin with. As for the scope, it's hard to tell unless there's obvious damage or it's an antique past it's prime. Try to get as good a quality scope as possible to start with. You would not put one ply tube tires on your mustang and expect to get the best performance, so...
Most rifles are capable of shooting quite accurately, and all things being equal, it's the shooters job of making it happen.
Ammunition should be considered as well. Toss your old military ball ammo and junk from overseas, both of'em. If you want to shoot accurately and consistently, you must spend the bucks for the best ammo you can afford.
You MUST KNOW what the BALLISTICS are for the Cal./type/weight ammo you will be shooting and the corresponding distance it will be shot from.

Make sure your rifle is CLEAN inside and out. A clean rifle is a happy rifle.
Make sure that your rifle 'fits' your body's frame and that you are familiar and practice good rifle shooting techniques.
'Zeroing' is best done from the prone position as that is the most steady position to shoot from.
Do you have a bi-pod attached? Whether you do or not, sandbag your rifle securely but still able to make small adjustments to the rifle position itself.
Set up a target with a 1" black dot at 50rds.
Remove the bolt.
Lay down with your rifle but stay OFF of it, touch it as little as possible at this point.
With out disturbing the rifle look through the bore downrange to your target. Locate the black dot and if necessary adjust your rifle from the **** end until you can see the dot through the bore. Keep making minor adjustments until the dot appears to be centered in the bore. Make sure rifle is secure and steady at this point.
Then without moving or touching the rifle, look through the scope using the correct eye relief distance and locate the black dot. Now using the Vertical(Elevation) and Horizontal(Windage) adjustment knobs, move the reticles(crosshairs) until they both are centered on the dot.
Again look through the bore to make sure that you have not moved the rifle and that the dot is still centered in the bore. If not, adjust the rifle again to center the dot, then go back to the scope and adjust as necessary to move the RETICLES to the center of the dot. It may be necessary to repeat this a few times before you have achieved this particular goal.
You do not mention brand/model of your scope. It probably adjusts the reticle or crosshairs in 1/4minute increments (1/4 inch increments with each individual click movement of the turret knobs at 100 yard distance). IT IS CRITICAL for you to know how your own scope adjusts.
Now, bolt back in and load 3 rounds of quality ammo.
You are going to shoot 3 rounds in succession without getting off the rifle or making any adjustments to the rifle or scope. You are looking for a 3 shot group to determine a rough average of how far and where the rounds are impacting initially. Use good shooting techniques, breath control, relax, sight picture, squeeeeeeze the trigger, follow through the scope, there is no need to take your eye off the scope while doing this, hold your shooting position for all 3 shots.
You will now have to make adjustments of the scope unless you are hitting the black dot already which is quite possible.
Remember that if your scope is a 1/4" adjustment at 100yds, it means that for each 'click' that you adjust either Vertically or Horizontally at 100rds, the reticle/crosshairs will move accordingly 1/4 of an inch Vertically or Horizontally. At 200yds, one click will move it 1/2 inch, at 300yrd it will move it 3/4 of an inch, at 400yrd, it will be 1 inch.
Right now you are at 50yrds distance from your target. Each click from here will move the RETICLES about 1/8 of an inch so estimate the distance that your most central shot of the 3 you fired, is from the black dot and adjust accordingly. You're not moving the RIFLE here, you are simply moving the scope RETICLES so that your point of aim and point of impact coincides.
Now load 3 more rounds of ammo and repeat as above. You should only have to use about 9 rounds to get on target, the black dot.
Once you are hitting the black dot at the 50yrd line, move back to the 100yrd line. Put a fresh black dot on your target and repeat the steps from above. Your first 3 shots from the 100yrd line should be about 1/2 to 1 inch low. Don't follow the bullet strikes! Keep your point of aim and the crosshairs ON the black dot no matter where the bullets are striking on the target. Remember, now at 100yrds your RETICLES will move 1/4inch with each 'click' of adjustment of the turret knobs.
Adjust the scope as needed at this point. Once you are 'ON TARGET'(hitting the black dot), you now have your 100yrd. 'ZERO'.
Now that you have this 100yrd ZERO, you must loosen the turret knobs , both the Vertical(Elevation) and the Horizontal(Windage) turrets and align the '0' on the knobs with the '0' on the scope at the base of each knob. Now tighten the set screws and you are set to go. If you want to know your 200yrd 'ZERO', simply move back to the 200yrd line, your 'come-up' or elevation adjustment should be about 7-9 clicks, at least for .308 168grn HPBT, but you will figure it out for the Cal./brand/wght ammo you are using. WHATEVER the 'come-up' you need to make at 200, 300,400yrds or wherever, be sure to make note of the number of clicks you used to find the Zero for that distance. Use a fine point endelible marker and actually write the ZERO info on thestock of your rifle. You don't need to mark anything for the 100yrd ZERO, it's a given already. Write; 200/9, 300/18 and so on. You should also get your ZERO for the intermidiate, 150yrd, 250yrds etc, distances as well.
Remember that weather conditions, source and intesity of light conditions, your own body condition at any particular moment or day can have an affecf on how you and/or your rifle shoot. Good luck.

Crosshairs on pentax 4.5x14x42 don't move


With modern rifle scopes the crosshairs do not move.They are designed so that the crosshairs are always centered.I have not seen a scope with crosshairs that move for about 40 years.If your scope has 1/4 minute clicks, then the strike of the bullet moves 1/4 inch at 100 yards for every click.1 inch for 4 clicks and so on.If you rifle shoots 6 inches high at 100 yards you should turn it down 24 clicks to strike dead on.Many hunters and shooters adjust their scopes to strike 1 1/2 inches high at 100 yards.Then it will be accurate to about 300 yards without further adjustment.

Simmons scope that will not stay on target


Mount the rifle with the scope and make a mark on the backstop right where the crosshairs are pointed at

Shoot several times, several shots will surley jolt the scope some.

If the crosshairs have moved much past your mark then this would indicate the scope is the issue.

If the crosshairs are still pretty well centered to the mark, its not the scope.

If at the same time your grouping looks terrible, and your scope still is on the mark, and the gun is WELL mounted, then the issue is with the accuracy of the rifle.
Make sure the rifle is mounted good for this to ba accurate .
Hope this helps
