Shoots realy low cant get it to raise enough

You need to sight in the scope and rifle to 100 yards then reset the dial making sure the knob as the manual says
do a check sight in
Then you turn on the electronics
the drop number you input is 112 and the BC is 55
as you haven't given an altitude for sight in or shoot site I have allowed for them being equal
you now shoot at a target at 400 yards and for each inch below or above the aim point add or subtract 6 from the drop number
drop number entered is 112 and your shot is 4 inches low
4x6=24 so your new drop number is 136
and if 4 inches high the drop number is 4x-6=-24 new drop number 88 so you now change the inputted drop number to the ones you have and shoot a few groups at 400 to confirm point of impact and aim point and adjust accordingly
Forgot to explain that the 112 drop number is the calculated drop for your round at 750 yards and that you are changing it by confirming the actual drop at 400 and the scope is calculating internally for 750

Off which way at 25 feet. If the gun is shooting low at this distance i would back off to 25 yards. It may shoot low because the scope is mounted a about 1 1/2 inch above the bore of the gun. In the 25 feet there is not enough bullet rise to compensate for that sight being that far above the bore. You may have to go with a red dot type or just add a laser if you are going to stick inside your 25 foot zone.

If you are going to attempt to sight in your rifle scope for hunting or just shooting, you will need a basic understanding of what a Minute of Angle is.

Think of a circle as it is divided into 360 degrees.

Each degree is divided into 60 minutes.

Each minute is divided into 60 seconds, but we don't use that for ballistics, seconds of angle are just used in machine shops and in rocket science.

Minute of Angle

1 MOA = 1/60th of a degree

1 MOA = 1.047 inches at 100 yards
Most accurate long range scopes are set in quarter clicks (4 clicks = 1 MOA) or eighth clicks (8 clicks = 1 MOA) but less accurate short range scopes are sometimes set in half MOA clicks (2 clicks = 1 MOA)? which to me is the opposite as it should be.

For a .308 the difference between shooting at 100 yards and at 500 yards is about 11 MOA. That adjustment with a scope using eighth clicks is 88 clicks.

Most accuracy testing is done at 100 yards, because it makes the math easier, and it is close enough to see the bullet holes through a spotting scope.

Folks usually say that 1 MOA is equal to 1 inch at 100 yards, which is almost exactly correct, as 1 MOA is only slightly more than 1 inch at 100 yards. But for what we are doing it is close enough. Now think it on out to 300 yards, 1 MOA is then equal to 3 inches. So if your shots are 1 inch off to the left at 100 yards; out at 300 yards, you will be off to the left 4 inches. Clear as mud? Hope this helps.

No, this is not a scope issue. The scope is raised above the centerline of the barrel, thus at 10 yards, the barrell is actually slightly raised in relation to the centerline of the scope in order to hit your point of aim. Since the front of the barrel is slightly inclined, at 25 yards the bullet is still rising in relation to the scope alignment. Backing up to 50 yards you will begin to see the bullet start to drop back down, at 100 yards it may drop as much as 8-10 inches, and at 200 yards, it may drop as much as 52 inches. This is assuming that you are shooting a standard velocity .22 long rifle cartridge (1050 feet per second or so).

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.

I don't think the tube holding the cross hairs will go up that high, and shimming the front base, I don't know. What you need is a new cross hair with the dots below the cross, They will raise your line of sight past the 350 zero. Or,,,,, just put the cross at the top of your target, 600 yards without the right scope is a long shot. I hope you have a heavy barrel target rifle in 308 or bigger. My M42 is unbelievable, but, It will shoot better than me all day long and I rarely go over 200 yards. I tried the 600 yard line once, didn't like it. Oh I could hit the target, but I like hitting doorknobs at 200 yards better. What are you shooting anyway? I hope your not trying to stretch out a 223 to the max.

this is a common fault with fitting cheep mounts on your rifle,,
a nikon scope is realy for "air rifles" but having sead that there very strong scopes, i have 4 of them all fitted on full bore rifles,,308,(7.62) .303 british enfield, .22-250 and a 357 mag rifle? and none of them have shook apart yet! and i found that on a full bore they do shoot low,,,to get over this problem you could change the mounts to the ajustable type witch is pricy,,or a cheep way out is to pack the bottom of the rear scope mount out with a strip of 35mm film,,(the rear being the end you look throw),you only need to life the rear end of your scope 25th of an inch to rise its point of impact by 6" inchs at 100 yds as the nikon scope is one click (1 thou of an inch) = 1/4 of an inch at 100 yds so 25 thou will raze it by 6.25 inches (- bullet drop!) just undo the scews that hold down the rear of the scope and slip a bit of old 35mm film under the scope then nip the scews back up again and try it out,,,if its still low put in a bit more packing,,,but you can only get about 4 bits of film in before its likley to bend the scope tube!!! mind you with 4 bit under it you will be shooting at the moon??? its much cheeper that ajustable mounts,, all my scopes are packed out like this and they dont creep or slide or loos point of aim even after 300 rounds in a day?

When adjusting a scope just move a few clicks at the time, after every few clicks tap the scope with a screw driver handle. Fire 2 rounds for group tap and fire the third round it should be in line with the 2. Keep that up till on target. Let the gun sit till cold and re-fire for grouping, 2 rounds, wait then the third. To keep shooting round after round can get the reciver warm enough to wedge the scope in its bases, causing your problem. 

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. :)
