    I know there are ballistic programs but with so many variables I never use these programs.
    I just want to know if my .22LR is sighted in at 25 meters with Eley Tenex Ultimate EPS how much will the bullet drop be at 100 meters.
    The scope is on low mounts.
    I want to use the turret to dail in for different distances but if the drop is too much I dont want a 0.125 scope but would rather look at a 0.25 scope.

    Thanks

    One sure way to find out .....take it to the range see what it does on paper.

    Don`t dis-count ballistic tables. You need to start some place.

    To go to the range is the best answer, but this weekend its not possible for me. I want to buy a new scope so I need to know this before making my mind up. I don't want to order the scope only 10 days from now:)
    If someone who has allready tested it himself can respond I can order my new scope today allready. Even if its out by up to 1cm then its still fine with me

    Probably in the neighborhood of 8"

    8'' sounds about right. Thanks for confirming this figure I thought it might be give or take.
    So it will take 64 clicks on a .125 scope and 32 clicks on a .25 scope to get on target at 100 meters.
    I wonder how many clicks is a complete 360 degree rotation on a 0.125 scope. I'm at work, can't test it myself now unfortunately.

    I just sighted in my Ruger 10-22 at 100 yards with Bushnell Banner 1.5-4.5x scope and 32 clicks sounds about right. Then confirmed/adjusted on 50 yards and adjusted so it shoots about 1" high and at 2-3" low at 100 yards. I really don't plan on shooting past 100 yards, but might, I mean, it's not like the ammo is expensive.

    Shooting a 10/22 with an 18" Kidd barrel that is zeroed for 50 yards, my come up is 7.5MOA at 100 shooting Wolf Match Target.

    depends on subsonic,standard,supersonic,hyper velocity.

    I think the federal bulk is around 5.5"

    I looked the ballistic tables up after the season finale of Top Shot. In the "Call Your Shot" competition, Dustin chose a Volquestrian rifle, shooting a golf ball off a tee at 100 yards. I would guess the rifle was zeroed at 25 yards. I figured he knew there was a slim to no chance that the other competitors would know the bullet drop at that range. He hit and the other two missed way low. The table I looked up had a drop of about 6".

    i have a zero of 50 yards, it drop 6.5 to 7 inches at 100 yards, using federal bulk ammo.

    Guys, thanks for all the responses. I'm sorted. I tested the only .125moa scope I have and found it has 72 clicks per full rotation. That is 9 moa. As I need only 64 clicks for up to 100 meters, if zero'd at 25 meters, I will be able to dail in the distance using less than a full 360 degree rotation of the turret from 25 meters to 100 meters.

    Does all .125 scopes have the same number of clicks per full rotation or not? I've come across a scope that has a 25moa adjustment range per rotation! But that is a scope made specifically for that reason.

    The link above is a free ballistics calculator from Nikon. If you simply want an approximate drop just put in your zero, your target distance, and that ammo and whoolah. Done.

    For Eley Tenex your drop with a 25 meters (about 27 yards) zero for a 100 meter (about 109 yard) target is right at 11 inches. I'm not sure what Eley Tenex Utimate EPS is, and if that is a different round or not.

    I assume the 8" drop people were coming up with is with a 25 yard zero and 100 yard target. That would be correct. I am showing a 8.21" drop if you are talking yards not meters.

    It has 100's of different bullets/calibers, you can set your zero distance, target distance, barometric pressure, altitude, temperature, yeah...

    It will give some pretty accurate bullet drop numbers for your .22lr.

    I've just last night looked at this site, and used it. I was worried because it said drop will be 11 inches. In real life its 8 inches as confirmed here. That is a difference of 3 inches.... Who is right? That is why I dont want to use balistics software. I like to use information from actual field test by actual people, which I hope is more accurate.

    As you see from my edit, are you sure your range is right. The difference between meters and yards will give you that 3" differential, just as being off on your zero distance and/or target distance can also give you discrepancies.

    Yes, I even changed the yards to meters, entered the correct scope hight. And I've sellected the correct bullet. I'm going to try to go to the range today and would like to compare actual results to the results from ballistics software.
    I'm sure someone else have done this before?

    I've just read this and basically this is the reason I don't trust software.

    ''Testing the predictive qualities of software
    Due to the practical inability to know in advance and compensate for all the variables of flight, no software simulation, however advanced, will yield predictions that will always perfectly match real world trajectories. It is however possible to obtain predictions that are very close to actual flight behaviour''

    That is why I asked real life figures.:)

    I have, and found that apart from the error in my shooting, variations in bullets, and what could be assumed to be potentially different velocities (between the velocity used on the ballistics calculator and actual velocity from MY rifle), that it was pretty spot on. I used it for .22lr (2 different brands of ammo), .223, and .308. I even marked a POA above my intended target based on the drop it gave me, and the average of my shots was right there, albeit I didn't account for windage.

    If 11'' is the actual drop, then a .125 scope with 9 moa adjustments per turret rotation is not going to work for me.

    Better hope it is closer to 8" for you then! :)

    Okay, I went to the range. To compare my actual results with the software.
    Settings used: Scope hight 1.5. Eley Tenex ammo. 25 meter zero.
    According to the software I must be shooting 0.95'' low at 50 meters.
    My actual tested figure was 0.59''.
    In milimeters, what I use to measure, the difference between actual tests and the software is rather a lot.
    Software is 24mm
    My actual results: 15mm.
    That is a big difference to me. Unfortunately I could not test at 100 meters as time run out. The range was closed before I could do all I wanted to. At least next weekend is still there.
    I'm just very dissapointed in my scope. Its tracking system is not 100% as reliable as my Leupold VX-1.

    8" is probably close. Your left to right at a hundred is your bigger problem with wind. They tend to get taken pretty hard by 10 MPH or so.

    You are right. The wind plays a big factor. At 50 meters today the wind made it hit 10mm/0.40'' to the left. I do not know how fast the wind was however, but it was quite heavy. Strange that at 25 meters the effect of the wind is about nil. Just double that distance and you can see the difference.
