First, adjust wind-age and elevation to center or zero position. Remove your scope from the gun and make sure that the scope mounts are aligned, this is critical. Purchase an alignment tool is necessary. Then remount the scope. The scope should seat in the mounts without binding. If it does bind, the mounts are not aligned.
Start sighting in at close range,10 to 30 yards, then move out to 100 yards.

How do i use a tasco 28A


1. Insert the Bore Stud into the Stanchion while aligning the arrows as shows. Insert the assembled scope guide into the muzzle of your rifle with the grid pattern upright. 2. Select the Aperture Cap that fits your objective rim. Place it over the objective end of your rifle scope and press until it fits flatly against the rim. 3. Using the Adjustable Scale measure the top of your rifle scope tube to the center of the rifle bore as follows: Open the rifle breach. Rest the upper arm of the scale on the scope tube before or behind the windage and elevation turrets. The scale markings should be facing towards you reading vertically and ascending from bottom to top. Slide the lower end of the scale up or down until it is touching the center point of the bore. On center fire rifles the center point will be the firing pin. On rimfire models the center will be the shell extractor. Read the number that corresponds to the indicator marked "CF". Make a note of the reading. 4. Aim the rifle toward a light, flatly lit area such as a wall or open sky. Caution: Do Not Look At The Sun As Permanent Eye Injury Could Result. 5. While keeping the riflescope at the right distance to see the full field of view, sight through it on the grid pattern. Move the stanchion right or left until the bold centerline is parallel to the vertical reticule wire. Turn the windage dial right or left until the vertical reticule is aligned with the grid centerline. 6. Use the reading from the scale to align the horizontal reticule wire. Find the numbered horizontal grid line that corresponds to the number on the scale. Turn the elevation dial right or left until the horizontal reticule wire aligns with this corresponding grid line. 7. To make your final zeroing adjustments remove the scope guide from the bore of your rifle. WARNING: FIREING YOUR RIFLE WITHOUT REMOVING THE SCOPE GUIDE MAY CAUSE DAMAGE TO YOUR RIFLE AND OR CAUSE YOU INJURY At a range or other safe area test fire a group of three rounds of the same type ammunition at a target at least 50 yards away. Refine your scope alignment by adjusting the windage and elevation dials. Move to your desired distance from the target and test fire another group and make your final windage and elevation adjustments. 8. Restore the stud tension by pressing the end of the spring.

I cant site the scope in the adjustment ot make it go left to right will not adjust


Put the gun in a vise. Look into a mirror and align the crosshairs so that you have one set of crosshairs when viewing in the mirror. The windage adjustment is maxed to the side you are trying to adjust . This will set the parallax of the crosshairs close to zero and allow adjustment in all directions.

CAN NOT ZERO GUN


You may try to bore sight it first. Pull the bolt and setting the gun on a good rest sight thru the barrel at a dot on the wall within ten feet. Then adjust the scope to that dot. As you adjust the scope tap the bore of the scope with a screw driver handle, tap it after each adjustment not hard, but enough to give it a sharp jolt. Once you are close here, move out to the range and shoot at 15 yards. Using a rest, again tap the scope after each adjustment. Then move out to 50 yards and you will want to be shooting high 1.5 to 2 inches here. Shoot slow keep the barrel cool and try for 2 shot groups till you have got the scope dialed in. Then move out to 100 yards for your preference of zero. Remember use the same ammo you will hunt with or at least the same bullet weight. If you can't get her to get on paper you can try to loosen the scope in the rings, one at the time once the gun is a little warm. Loosen the barrel ring first then snug it back down and then the receiver ring. If your group moved now, she was in a bind due to a cold gun at set up / installation.

Bought a 444 Handi Rifle with a Bushnell 3200 firefly scope on it. Tried to sight it in at 75yds yesterday. I adjusted the elevation up 6 to 8 "inches" and I am not noticing any change. Still shooting low....


O.K Your gun packs a good kick, but you might try to first, tap the scope with the handle of a fair sized screw driver, after each adjustment. Next do not adjust it so many clicks at the time just 3 clicks and see if she moves the point of impact. Try a few clicks and tap the main shaft of the scope kind of rap it then shoot for group, fair 2 rounds to see if it has settled down, then adjust a few, tap and fire. work slow with a older scope and try to stock up on the bullets you decide to go with and zero for them. Any other round you use do not zero, but use go old windage to pratice with.

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.

Lost caps


I'm not sure how this got posted in the car audio section...

 

If the scope was manufactured by a well established company, you should be able to get a new cap from them.

 

If you cannot locate the manufacturer, you can move the other cap to the windage adjustment to set the windage. Then when you're finished, move the cap back to the elevation adjustment.

 

Even if you use it for a shooting discipline that requires constant adjustment, it's unlikely that you'll need to use the windage adjustment for anything other than setting the zero.
