Adjusting elevation turret for different ranges

If you are shooting in all but field target you are shooting at known distances so no need for a range finder.

Yes every time you shoot you are adjusting your elevation rather its because you are shooting at a different distance than you are zero'ed for or because of environmental conditions or because of pellet changes, typically the last two both apply.

Chairgun is your friend. You have to make sure you have accurate velocity, bc of the pellet and scope height numbers to get useful information from it. It will give you range cards in clicks, moa, or mils.

Google Chairgun. 

Yes you can determine the number of clicks needed by using a ballistic calculator. I prefer hawke Chairgun Pro, which is a free download for Mac or PC. You enter velocity, Ballistic Coefficient, scope height, ect. and then the zeroed and desired target range and it will spit out all the information. That's the easiest way to do it or you can use trial and error to figure it out with your exact gun.

"k_h_d"Just to be clear, I am referring to physically adjusting the elevation turret so the center of the crosshairs is exactly the point of impact. Not just holding over on a lower Mil-Dot.


Is there a way to calculate number of clicks for a different further range then original center?

Here is what I typically do at a competition or even a practice session.

Shot a (3) shot group and adjust elevation.
Shot another (3) shot group and make any further adjustments needed.
Shot for score.
Adjust if needed.

You can use just about any ballistics software to calculate the adjustments between distances, some will even factor in environmental conditions. In practice you are going to shot and adjust.

I prefer Strelok Pro on my smartphone, much easier to use with better interface.

15 bucks is nothing when you can save all your guns and switch between them and always get your holdover no matter what. Best investment (and probably cheapest) you will ever make in the shooting world.

Just remember, it is only as accurate as the numbers you put in. If it shows wrong, you did something wrong. If everything is as it should with the numbers, that miss was on you or you overestimated your guns capabilities.

I use holdover because I never trusted my scopes enough to use the turrets. However, I now use SWFA scopes and they are known to be good and true in the turrets, so it would be really cool to start using the turrets, Wich I will. I wouldn't trust a Chinese scope though unless I personally did a proper test of the turrets. Like Ed did with his own scope that's made in China a but with German glass here:

Its a mildot (usmc) I believe it is calibrated for 10x

Yes

For field target shooting both methods are used. I only shoot hunter class and as such I'm limited by the rules to 12x max so even if a scope has a max 16x the power must be turned down to 12x for competition. The hunter class also prohibits using the scope turrets for "clicking on" so all shooting during a match must be done using holdover, Kentucky windage, plus all distances must be determined by "scope rangefinding". By the way, scope rangefinding is rather challenging at the 12x max setting and distances part 30 yards or so. Most HFT shooters mark their side wheel or AO with yardages at different sharp focus distances and then refer to memory or a "dope sheet" to determine the appropriate hold over/under. I'm an odd duck in the sense that I mark my AO or side wheel with symbols that represent which "reticle feature" to hold on the killzone after a sharp focus. For example.........

In the above pic if the pointer lines up with a + after focusing I know to hold "crosshair on".
If the . lines up with the pointer I know to hold "the first lower mil dot" on the killzone.
If the stacked .|. lines up with the pointer I know to hold between "the first lower mil dot and second lower mil dot" on the killzone.

Other field target classes are unlimited to scope power and are allowed to "click on the killzone" after determining the distance using the scope. LOL....here are a couple examples of side wheels that have been marked with actual yardages and other bells and whistles for classes other than hunter............
