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.

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.

Point of impact changes with every shot


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

Will my scope remain zeroed at different distances?


You need to look at your bullet ballistics, Most guns should shoot dead on at say 15 - 17 yards out, to be on center at 100. Line of sight is straight the bullet must go over the line of sight to come back down and cross again so far out -- make sense? So no you will be a little high at 100 but may be close at 130 - 150. Ck on line for your ballistics with the bullet manufacture.

Zeroing scope adjustment


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.
