JG M4 S-System asked How do I adjust the windage and elevation on my Rifle Scope?

I tried adjusting it and it worked from like 30 feet away. I was shooting at a target from that far away. I manage to hit every single target. I moved farther and a different spot, aimed the reticule(crosshair) at the target, missed every shot. I saw my bullet shoot the ground and was hitting it only when I moved the crosshair up and to the right. Is there a way to fix this?

And got the following answer:

Let me guess? You’re, kind ‘a, new at this – huh! You have my sympathies; I grew up in a fatherless home; my mother had a strong, even an irrational, fear of guns; and, other than occasional visits from my Marine Corps uncles, I had no one to really teach me how to use firearms – Heck, no gun of any kind was even allowed in our home.

I will never forget what I went through trying to figure out how to sight-in my first 22LR rifle. It was a ridiculously cheap little scope; and I tried every conceivable adjustment before it finally started to hit at, about, 50 yards’ distance.

Tell ya what! I’m going to try to start you out nice ‘n easy – OK. Let’s begin with an explanation of what bullet trajectory is and how bullets really fly.

Now, because all bullets in different calibers and in different rifles have different flight characteristics and trajectories, we’re going to have to make a basic assumption, here: I’m going to take a wild ‘n crazy guess and say that we’re, probably, dealing with a 40 grain 22 long rifle caliber bullet and a 22 caliber rifle. The scope is, something less than, state-of-the-art. (How ’m I doing?)

First thing you’ve got to do is to get that scope mounted nice and plumb on top of that rifle – You want the crosshairs perfectly vertical and horizontal; and you don’t want to use an inappropriate set of mounts that’ll fix the scope too high above the barrel’s bore centerline.

Here’s a hot news flash: Rifle scopes, even 22 rifle scopes, should NOT be setup to operate at 30 feet. ‘Bore sighting’ is for what you’re doing, kind ‘a, overkill. All you need is a couple of (say) 3’ x 3’ pieces of cardboard. You will sight-in your new scope by either lying down or sitting at a shooting bench and bracing the rifle’s fore-end – but NOT its barrel – over something like a rolled up blanket or jacket.

OK, if you’re normal, I know how unpleasant this can be; but, READ THE INSTRUCTIONS that came with the scope. This will give you some important information about how to sight-in that scope. When you’re ready to begin, remove the covers on the vertical and horizontal adjustment knobs. You’ll see a bunch of little, ‘hash marks’ arranged in a circle around a screw. Generally, but not always, each of these marks will cause its respective crosshair to move in a selected direction by either 1 MOA (Minute-Of-Angle) or some increment of 1 MOA.

Here’s an explanation of MOA:

Now, after you’ve digested this information, place those 3 foot square pieces of cardboard at: 12, 20, and 40 yards. Get, ‘on the paper’ at 12 yards. (Because of the way a 22LR bullet flies you’re going to want these bullets to hit about a half inch low @ 12 yards. You can begin to make both the vertical AND horizontal adjustments immediately in order to bring the POI (Point-Of-Impact) closer to each respective centerline.

The really tricky adjustment is the vertical POI. (Study that explanation of bullet trajectory, again; and remember it’s going to be different for every: caliber, bullet, and rifle.) Here’s an explanation of 22LR trajectory AND a very useful graphic chart for the high velocity 22LR bullet.

The chart shows you several important things: (1) You’re going to want to mount that scope no higher than 1.5 inches above the rifle’s bore centerline. (It, probably, already is.) (2) You want the scope to be sighted-in DEAD CENTER – not at 30 feet, but – at 20 YARDS.

That’s twice the distance at which you originally tried to set this scope up! (3) If you look closely at the chart you’ll notice that close-in the bullet is going to be flying, ‘level’ at 20 yards. This is where you want your crosshairs AND the bullet’s POI to exactly intersect.

At 40 yards the POI will move up by 1/2 inch. At 66 yards the bullet will have dropped below the line-of-sight. This does NOT mean that you cannot use a 22LR bullet effectively beyond 66 yards. The bullet is still very much, ‘alive’ and potentially lethal to whatever it hits. (I’ve, often, used a 22LR rifle at 75 to 80 yards; it’s called, ‘holdover’.)

Hope this gets you off to a good start!

Henry f asked How do you adjust your rifle scope on the move for longer shots ?


And got the following answer:

if you are willing to take these long range shots you should practice them before hand. see how low you hit for each yardage and adjust the gun by AIMING higher not by changing the scopes elevation. So practice practice practice man, thats what it takes to give you that confindence in the field. Hope I was of some help.

Ozyhan asked What is the side focus and what does adjustable objective mean?

Some rifle scopes have a side focus on it but don’t get its purpose and on the other hand some rifle scopes have adjustable objective lablelled on it. What are their purposes and what do they mean?

And got the following answer:

Both are used to adjust for “parallax”. The knob on the left side of the scope body just makes it more convenient to change this setting when shooting different distances.

Parallax is a condition that occurs when the image of the target is not focused precisely on the reticle plane. It’s visible when there is an apparent movement between the reticle and the target when the shooter moves his head or, in extreme cases, on out-of-focus sight picture.

It is physically impossible for the human eye to focus on 2 things at the same time that are at different distances. The parallax adjustment, whether it is made at the objective lens or with the knob on the scope body, solves this by bringing both the crosshairs and the target that is viewed through the scope into sharp focus at the same time.

Ninja Sour Death asked Is a 3-9 x 32mm rifle scope powerful enough for varmit hunting?

I have a Bushnell 3-9 x 32mm rifle scope and I am contemplating selling it for a new scope for my AR-15. I typically shoot anywhere below 400 yards. Is this scope usable for this type of hunting?

And got the following answer:

Depends on the varmints you are hunting. If you are hunting in wide open snow, trying to nail fox or coyotes running on top of the snow – this will work for you.

However, if you are trying to nail smaller varmints, and, you are not seeing the whole animal due to grass or shrubs – a bit more power will be better.

That 32mm front lens – this is what brings in the light that your eye see’s. Early in the morining – a 32mm will not let you notice a coyote standing under a tree……. but a larger front lens like 44mm or 50mm will let you see it. And if you have a 30mm body instead of the usual 1″ body – you will see it even better because the 30mm are much more effecient getting the light from the front of the scope to your eye. No free lunch – this will add weight and cost to the scope – but it is a nice upgrade.

You should take a peek at the BSA line of Sweet 223 scopes. The hunting model is 4-12x or so and both have a BDC top target turret that once calibrated lets you instantly adjust the crosshair zero from 25 yards to 375 yards so you can shoot dead on target with no hold over. The bigger 6-18x or so is too much for hunting – up close at 50yd you would only see fur – with no idea if your scope is on the tail or the ear….. and at 18x is shows every wiggle and heartbeat like a friggen earthquake.

I have the BSA Sweer 223 on my varmint AR and varmint bolt gun for Alaskan winter varmints. They are affordable and have worked just great the past 3 years problem free. The new models they make now have side focus – very handy if you wear glasses or share a rifle with a buddy. You can see them at

Good Luck

asked My rifle scope shoots to much to the right. What am I doing wrong?

My .223 rifle scope shoots to much to the right. I can not adjust anymore to the left. I am using a zeiss conquest 6.5-20X50 rifle scope. At just 25 yards, i am shooting 3 inches to the right. I have tried other distances such as 50 yards. I have an “elevated” scope mount to allow long range shooting. Please list all possible things that I could be doing wrong.

And got the following answer:

First thing to do is check your mounts. Are they tight? Then try tightening the screws in a different sequence. Tighten front mount screws then rear mount. Then tighten rear mount screws first, then the front mount screws. Sometimes the tightening sequence can have an impact. Then try putting a shim in your mount-something thin like a piece of aluminum foil. It won’t be noticeable and if it moves the scope enough your problem is solved. Try shimming the front on one side, then the other. If it is extreme, you might shim the front scope on the right and the rear scope on the left. Or reverse. The idea, of course, is to keep experimenting until you get it right. Takie your screwdrivers and plenty of ammo to the range, set up your target at 25 yards, and shoot away. If nothing seems to work, then try a gunsmith. This is one of those problems I hate to spend money on a gunsmith to solve if I can figure it out for myself. Experiment and see what happens. There is the possibility your scope is simply out of alignment. Good luck with this.

xerographic26 asked Can you put a rifle scope on a muzzleloader?

I was told by someone that a rifle scope on a muzzle loader will break due to the shock when the weapon is fired. They said you have to mount a shotgun scope or muzzle loader scope on a muzzle loader so it wont break.
Yeah I kind of thought he didn’t know what he was talking about, but I have no experience with muzzleloaders so I wasnt 100% sure. Thanks for the replies.

And got the following answer:

The biggest difference between a “rifle” scope and a “shotgun/ muzzle loader” scope is the rifle scope is usually set to be parallax free at 100 yards and the shotgun/ muzzle loader scopes are normally set for 50 or 75 yards. Your eye can’t focus on 2 objects on different planes so the scope is adjusted to have the cross hairs and target appear to be the same distance. Some scopes have adjustable objective lenses to set it for exact yardage. As far as the scopes holding up, any quality scope will handle the recoil. Just make sure you have enough eye relief so you don’t get a case of “glass rash”. I’ve never had a scope hit me but I’ve seen enough people with the tell-tale sign of the half moon cut over their eye. Just remember to wear ear and eye protection when shooting. Good luck and safe shooting.

jdfuente2006 asked When sighting a .22 cal rifle, how far is the ideal distance of the target assuming i use a scope?

I am trying to bore sight my .22 rifle scope. I was just wondering the effective range of the bullet and how far should i set my target.

And got the following answer:

Depends on the range that you intend to shoot. Usually 50-75 yards.

Are you “bore sighting” or “sighting-in”? Bore sighting is literally looking down the bore of your gun at a target and adjusting the scope to that it is centered on the target. Bore sighting can also be done with a mechanical device or laser. Due to the ballistics of the bullet, it will still be rough, but enough to get you “on paper”. You must still “sight-in” with some test shots to get your scope zeroed perfectly.

Rdex asked My rifle scope will not adjust anymore to the right?

My i need to adjust my scope to the right so I can finish zeroing it. It will not turn anymore and it is mounted fine. My guess the scope is broken or poorly made. I have 17hmr with a center point scope 4×16.

And got the following answer:

You can place shims under the ring in the appropriate place and start over.That’s what a gunsmith will do,if the scope is just run out of adjustment. The shims can be made from a soda can
