Hello,
Using Strelok Pro, I zeroed my rifle in @100yds. Ballistics charts says absolute bullet drop is 2.6 inches @ 100yds. Shouldn't it be 0 inches at that distance? Any help would be appreciated.

Click on everything in green in that order to find the area to adjust 😉 Hope that helps

"Absolute" drop is exactly that, the drop of the bullet at that distance given the other parameters you entered, it has nothing to do with where you are zeroed or holds.


In Strelok when in the chart section click the gear icon at the bottom and unselect that option if you don't want to see it.
Select "Show Elevation, MOA" or inches or clicks depending what you want to see.

I believe you have several things incorrect in your scope set-up. The scope you selected is: Leupold FX-II 2.5 x 28mm Scout Rifle Scope: 1/4 MOA click windage and elevation dials.

1) You changed the Vert./Hor. click from 0.25" clicks to 0.5" (ERROR).
2) You also selected SCOPE CLICK UNITS of inches a 100yards (SMOA). The Scout uses MOA, not SMOA (ERROR). MOA is 1.0472" at 100yards, SMOA (SHOOTER'S Minutes Of Angle) is 1.0". Not a major difference but still will cause you problems.
3) Look at the ballistic table (TABLE icon, far right), then turn off SHOW ABSOLUTE DROP, INCHES. Absolute Drop – regardless of zero distance, drop measured from bore-line at distances as if the rifle was fired perfectly level at 0°. Useful, but typically only used in INCLINED FIRE calculations.
4) What you should select is SHOW ELEVATION, MOA and SHOW ELEVATION, MOA.
5) There are some other options you can choose such as SHOW ELEV./WINDAGE, INCHES and in the HOME menu option (GEAR icon) SHOW CLICKS in 1 3/4 layout but I would stick with correcting #1 through #4 first.

I didn't go any further in research since the screen shots were limited and these issues are enough to cause you problems.

    Yes. A zeroed rifle still has a drop. Gravity always exists.

    That is my set up for a Camp Perry rifle with a totally different scope than the Leupold that I selected. I had to fudge the adjustments and options to make S.P. work for that rifle and scope combo.

    I am not the O.P. I was just offering advice for him to check the zero settings. I believe 6.5sh has given him the information that he needs to correct his issue.

    Kind Regards,

    Jon

    Dude. Rifle bullets dont work like that. You point at a target, yank the trigger and the bullet hits the target.

    The whole "bullet drop" myth and "time of flight" thing is a joke we play on newbies. Havnt you played call-o-doody ?

    I await my punishment.

    You're confusing "absolute drop" with flight path above or below the line of sight. (Ordinate)
    The bullet starts dropping from the bore line the moment it leaves the barrel regardless of the angle of departure.
    The "ordinate" is the amount of vertical angle the bullet is set at via the angle of the barrel at bullet departure which is usually tracking on a relatively upward path for part of it's trajectory but, from the perspective of the angle of ordinate, the bullet drops down from the line of sight along the rifle bore, immediately it leaves the barrel.

    Thank you. Have you tested Speed Drop Factor feature, are you satisfied?
    Yes, thank you for a great product.
    I've been using Strelock pro for 18 months maybe 2 years & prefer it over the others I've used.
    It's so damn easy & fast when I want to adjust wind & such.
    Yes, I have been tinkering with the "SDF" charts & I like it a lot.

    Where is the SDF chart ?

    It's 3/4 the way down the projectile data input screen.
    So from the main "shoot data" screen where you see the the "calculate button, just tap on the rifle type box directly above the "calculate button then, tap on the projectile data box which comes up in the new page. Scroll down to where you see the "G1, G7 etc buttons & it's right above those. Tap that "speed drop factor button" & you'll see the chart/table for your projectile & velocity.

    If you're not familiar with how DSF works with the scope, you have to (-)/ under your 100yrd/meter zero then use your reticle & match the distance with the reticle.
    Once you've set the scope zero to say -1.4 mil, the ret should align with the distance numbers within the window the data allows for. So you should get say 334 meters = 3.3 mil & so on but, only within the drop scale factor & only at the medium ranges.

    Yeah it’s not there on IOS ... or maybe I’m utterly retarded

    Well it’s obvious not on mine. That’s why I asked if is needs to be enabled somewhere or are there bullets profiles it’s not there.


    Edit. Actually I found it on other bullet profiles but not for my 7SAW 162. Probably wasn’t meeting some kind of conditions.

    You probably have an MOA scope on that rifle profile.
