Unable to zero in on target?

3-9x50 full size range scope/20 is what my husband ordered and rec'd yesterday; unable to zero it in, tried adjusting elev. and windage spent over 100 pellets. couldn't get it zeroed in; he has a Gamo Black Cat 1200 which had trouble w/scope also. it kept landing too far rt and couldn't get the shot to go left- what is it we're figuring wrong? The target is approx. 30-35 yds.

Take it in because if he bumped the rail the scope is on it can make it inaccurate

How to use redfieeld 3x9x42 scope


Depends on the scope and rifle type to which it is attached.
I invested in an inexpensive laser bore such as this one for an AR: SightMark AccuDot Laser Bore Sight - 223 Model SM39001 (for AR-15)
Once the scope is mounted properly, and assuming you have not made any vertical or horizontal adjustments, set the rifle on a stable platform, insert the bore sight, point it at a target 50 (rimfire) to 100 (AR) yards out (works best in low light situation).
Once you have the laser centered on your target, make elevation and windage adjustments as necessary placing the scope cross hairs over the laser. Remove the bore sight and fire 3 rounds, then fine tune elevation and windage.

How do you make adjustments, towards the shot or towards center of the target?


You move the cross hairs to the shot. Set up your gun on a bench and start by firing at a target out at about 15 yards. Once you are "on paper" set your cross hairs on the center and fire a 3 shot group Adjust the scope to the group. if the group is down 3 inch and left 4 inch. Adjust your scope accordingly. Then Fire another 3 shot group, until you are shooting center. Every time you adjust your scope tap the barrel of the scope with a screwdriver handle to keep the cross hairs from sticking. Once on at 15 yards move out to your max range and adjust to that.

Is there a way to lower my turret after i've found my zero? my zero is at the 4th vertical tic mark on the 0.


No. The turret is what it is. If you want to re-set the turret to zero so that it is easy to return to for a specific distance, there should be a setscrew you can loosen, adjust the turret to zero, then re-tighten to lock it in place. If you are simply trying to lower the turret, you need to purchase a scope without target turrets.

What is the distance between the center reticle and the point where the lines thicken on the Leupold VX-III 6.5-20-40mm scope? (in terms of viewing a target at 100 yrds.)


This area is about the size of the kill zone of your typical white tail deer, about 18 inches at 100 yards. Try with a paper plate out at 100 yards and see how it fits inside this part of your cross hairs. Or use a life sized deer target for reference. Then use go up in power to see it work.

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.

Iam having troble with the tactical mil dot range estimating. Can you help me out


are you trying to zero it, or are you trying to figure out the estimating ranges, if so can you please specify better?

1. width or height ( in inches ) x 25.4 divided by number of the mils of the target as seen in the M3A = range in meters
OR
2. height in meters X 1000 /divided by the mil size of the target = range in meters.


if you need a chart

Windage and elevation adjustment all over the place


Sounds like you want to "re-sight" in your rifle. Make sure mounts are okay and tight. Look down barrel and then thru scope and eyeball windage and elevation adjustments so the scope seems to be fairly in line.

Clean barrel if it needs it.

For basic sight in, start at 25 yards with a large(3 to 4 feet) cardboard or wood backdrop around target (bullseye). Fire at target. Once done, look through scope and position rifle such that the shot mark you created is dead zero. Hold rifle very steady and you or buddy move windage and elevation adjustments until scope moves dead zero back toward original target (bullseye). Fine tune from there. Air cool rifle between rounds. Once dead eye, fire another round or two to check grouping. Check your ballistics (sometimes on ammo box) to see how height at 25 yards affects your desired dead on target (100 yards, 150 yards, 250 yards etc.). Adjust accordingly. Example: you may need to sight in at an inch high at 25 yards, depending on your dead on target distance..

Always remove sling from barrel when sighting in.

Try to sight in at similar temperature as you intended shooting temperatures, if possible.

If not black powder, avoid cleaning barrel between sight in and hunt/competition unless you note bad buildup inside.

If you change ammo, understand that that may affect performance. Once a preferred ammo is found, some even try to buy a decent quantity with the same lot number on the boxes if storage allows for such.

When you zoom your scope does the impact point change on the target? is that when you use mil dot?


No, the cross hairs remain fixed. The zoom serves only to magnify the field of view.

Tasco 6-24x42mm rifle scope parallax adjustment


Here's what you need to know about Mil Dots and rangefinding.

When you look through the scope you should see 5 mil dots on each axis, your scope may have broad lines taking place of the 5th mil dot if it is a "modified" mil dot scope. For measuring purposes, 1 mil is the distance from the center of one dot to the center of the one directly above or below it. 3/4 of a mil is the distance from the top of one dot to the bottom of the one above it, or the "space in between dots". 1/4 mil comprises a single dot, the space between the top of one dot and the bottom of that same dot.

A quick calculation is Size of Target (In Yards) x 1000 / Size of target in mils = Range in Yards

Miliradian or "Mil" is an angular unit of measure, so if you were shooting at 1000 yards and moved up 1 miliradian that would be one inch impact moved up.


Anyway lets say you have a 30" target and we need to find the range... using your scope you place the bottom of the target at the CENTER of a mil dot and count how many mils up, good estimation is key... I'll draw a little text diagram, an asterisk * will be the target top and bottom, and parentheses () will be a mill dot
( * )--------(  )-----*---(  )
Now lets assume the asterisk on the left is the bottom of your target and the one on the right is the top, I put Ten Hyphens in between each dot so if you count from the left you should get about 1.6 Mils. Its real easy to do it in your head, you already know two whole dots is one mil so you just have to estimate whats to the right (or top if you were looking down a scope).

So we know the target is 30" and we have a Mil Reading of 1.6
30/36= .833 so 30" is .833 Yards

So now we can use the equation .833 x 1000 / 1.6 = 520.6 Yards is the distance of the target


Now you can also use Mil dots to do hold over for when the target moves or for wind and elevation but that gets extremely complicated.

There are many books and websites to confirm what I've said here, but the best way is to go out to your range and talk to some long range shooters and show them your rifle/scope etc and get hands on help.

I have a Bushnell Sprotiew 4x, 15mm scope mounted on a Mossburg .22 rifle. My shots are hitting left six inches and low. Can you please tell me how to adjust this scope? Thank you.


Keep in mind Diane this is for a set distance. if you are taking a shot at a target further than your are set for (ie a target you wont get 3 shots @) remember how the bullet is travelling as it goes down range

one idea would be to set your rifle up down range and zero it in on a target (preferably paper) now adjust 1 MOA (try and have target @ 100 yards and 200 yards)

see how far the bullet moves for each moa adjustment. then check it against the next range.

this should remain constant @ a set number of inches per 100 yards.

so if you zero in @ 100 yards and then move 1 moa any direction and it adjusts (lets say and hope it is 1.047 inches") then you do the same for 200 yards. it should be twice as much movement. ie 2.094"

once you know what 1 moa represents on your scope you can adjust alot more accurately.

REMEBER the total inches of movement / adjustment per MOA is directly related to range (a precise range helps in shooting) so if your squirrel is 150 yards and your first shot is off 9" to adjust you divide 9" by the inches per moa so 1.5 (150 yards /100) X (Inches per 100 yards per moa you measured hopefully 1.047") its 9" divided by 2x1.047 = 9" / 2.094 = 4.29799

this number needs to be rounded to the nearest click on your scope (most are 1/4 MOA scopes and you can tell by looking at how many clicks/lines are inbewteen each large number on your windage and elevation dials

so to turn this into an adjustment we round 4.29799 to 4.25 which is 4.25 MOA or 17 clicks on a 1/4 min scope.

GL and any questions just post and ill help

not please rate this as fixya :)

Note i can provide EXACT information that would allow you to determine range, and windage and elevation adjustments by looking through scope and estimating range
then factoring in weather variables. NOTE you hafta enjoy math or just want to know how to shoot really well. :)
