SOURCE: Crosshairs are cocked to the right.

1. You first make a 'plumb line' to compare your cross hairs to. Go out about 15 - 25 meters and hand a length of para-cord or reasonably thick string (so you can find it easily in the scope), weight the end of the cord will some lead weights. I've even used some box end wrenches tied to the end in the field.

2. Fill a small ice-cream pale or similar with a couple liters of engine oil that the weights on your line with hang in. The oil will eliminate the line from swaying by dragging on the weights and ensuring verticality

3. Place the rifle in a secure mount and re-enforce with some sandbags.

4. Line up the scope (mounted on the rifle) with the line.

5. Use a small level to ensure the rifle is as close to perfectly level as you can make it, both front to back and side to side.

6. Loosen the scope in the rings and adjust the scope untill the cross hairs are vertically in-line with your plumb line.

7. When you are satisfied tighten the scope down and use some medium stength (blue) locktight on the screws. Use the manufacturer's suggested tourque spec and Avoid Over Tourqueing the screws. Some specs are as little as 10 - 20 INCH pounds. Thats around one to one and a half FOOT pounds

It takes some time and a little prep work - but if done with some care it can yield fine results. Remember to use caution when tourquing the screws - people often confuse INCH punds and FOOT pounds. the conversion is 12 Inch pounds to 1 Foot pound.

If you can't get a proper tourque wrench you are better off using a little less tourque and utilize some Lock Tite to make sure the screws wont move down the road.

Good luck!

SOURCE: 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.

hi, sounds like a convergence issue. try this...
  • Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.

  • Enter the menu on your TV. Use the remote control and bring up the menu.
  • Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  • Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  • Press "Enter." A crosshair pattern will appear on your screen.
  • Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.
  • Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.
  • Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.
  • Repeat these steps for all colors.

  • good luck!

    Sight in rifle and put the on top turret with zero facing back.do not let knob"click".Aim at animal and adjust power(3-9etc)until body is bracketed by both crosshairs.Look in little window in eyepiece for type of animal.Click top turret to proper yardage(200,300etc).This allows for bullet drop.I've had one on a .270 for 30 yrs and never used this feature.

    I zeroed in my 25/06 at 100 yards. at 200 yards 1/4 inch high using 2nd line on drop compensator , at 300 yards shot 41/2 inches high using 3rd line on compensator. What am I ding wrong


    It sounds good to me, don't forget, the 25-06 is a flat shooting round, you have your scope pointing up, the bullet crosses the line of sight twice, One at 100 yrds, your zero and the other on it's way down at about 500 yards. You can check the ballistic coefficient of that bullet and see where you need to be zeroing it in at. I would think about 250 yards, will be 1 1/2 low at 100 yards, 3/4 inches low at 200 yards, dead on at 250, then it will start coming down, say 8 inches low at 400 and 18 inches low at 500. Something like that. So your BDC will not be needed till you reach out past 300 yards, which is varmint country stuff. I have my .22 marlin sighted in at 100 yards, and it will put the lights out on anything at that range. You can probably find the charts on line someplace, if you don't have a reloading manual. Check it out.

    What is the bullet drop compensator range incroments


    Most BDC scopes have you line up a small set of wires on a target and then compensate for that range, some will be a holdover, some will have you raise the stadia to the zero. Basically a mildot, except the mildot is already set for an 18 inch target, you just raise the dots up. That is if you know your range. It can be confusing, A little practice and a bunch of ammo should have yo shooting ducks on the wing in no time. The range increments are usually 100 yards, maybe 4 dots, I don't think they would go much more than that.

    Crosshairs are cocked to the right.


    your scope has spun in the scope rings. Loosen the screws holding the scope to the rifle and turn scope until crosshairs are into position. Then tighten screws. You will need to sight in again. If it keeps moving replace scope rings.

    To adjust manual convergence on your projection TV, follow theses steps:
    1. Turn your TV on.
    2. Let it warm up for 30 minutes.
    3. Press the Menu button on your remote. The Main menu appears.
    4. Use your remote to select Function, and then press the joystick.
    5. Select Convergence, and then press the joystick. The Manual Convergence screen appears.
    6. Select Red, and then press the joystick. A series of crosshairs appears on the screen.
    7. Select one of the outside crosshairs by moving the joystick up/down/right/left or by pressing the 2 (up), 4 (left), 6 (right), or 8 (down) buttons on your remote. The method you use depends on the model of remote you have. Note: You must do the outside crosshairs first.
    1. In the crosshair you selected, if you can see a horizontal red line, use the CH up or CH down buttons to move the line so that it is superimposed on the horizontal center line of the crosshair. Note: Make the single horizontal line as white as possible.
    1. In the crosshair you selected, if you can see a vertical red line, use the Vol + or Vol - buttons to move the line so that it is superimposed on the vertical center line of the crosshair. Note: Make the single vertical line as white as possible.
    1. Repeat for all outside crosshairs, and then for the inside crosshair.
    2. Return to the Manual Convergence Screen, and select Blue, and then press the joystick.
    3. Repeat Steps 7 through 10 for Blue.
    4. Press the Menu button on your remote to exit.
    Important: The directions above work for most Samsung Rear Projection TVs. Yours may be different. For exact directions to perform manual convergence, see your user's manual. If you don't have your user's manual on hand, click HERE to view your manual on line.
    If you cannot get your Projection TV to converge, it may need to be serviced. To arrange a service appointment, call Samsung Customer Care at 1-800-Samsung (1-800-726-7864). Have your TV's model number and serial number on hand when you call.
