I just recently bought a Savage 93R17BTVS .17hmr. The optic is a simmons 3-12x40 and is calibrated for the .17hmr. Here is its description:
ProTarget Riflescopes
So you can hit the bull’s-eye. Pick your corner of the “X” with the precision of our new ProTarget riflescope. Extremely bright, sharp images, along with our TruPlex reticle make it easier than ever to pinpoint the smallest targets with your rimfire rifle. Fingertip-adjustable turrets get you zeroed quickly and most models feature side focus. Calibrated for either .22LR or .17HMR and available in 3-9x 40, 3-12x 40 and 6-18x 40 configurations.
3-9x 40 & 6-18x 40 will have ballistically calibrated turrets for .22 LR
3-12x 40 will have a ballistically calibrated turret for .17HMR
Multi-coated
Finger-tip adjustable turrets
3-12 & 6-18 will have side focus
1” tube design
PICS:
My problem here is that I do not know how to use the "ballistic calibrated turret"? The instructions are terrible and dont explain anything.
Here is a pic of the instructions and what it reads:
1. Sight in your rifle at the range.
- Sight in your rifle, firing 3 shot groups and adjust accordingly. Turn the elevation and windage the neccesary clicks to adjust the scope.
-Once the rifle is zeroed in, install and calibrate the adjustment dial set of your preference as follows:
2. Select your preffered dial set
Each scope comes with two sets of adjustment dials (one ea. windage and elevation dial per set) with one set marked in moa increments and a second dial marked in yards
3.Install the dial
Once you have selected the proper dial, installit as shown in Fig A in by removing the allen bolt (part 1) being careful to allign the 100yd mark with the index mark below the window on the elevation control (fig b). Tighten the screw making sure you have not rotated the knob and that it is still on 100yds.
4. Using the BDC riflesope
The bdc dial automatically adjusts elevation to take into account bullet holdover for distances beyond the sight in distance. Once you know the distance to the target adjust the BDC dial to that distance. You have now corrected for bullet drop.
Ok so the windage knob is 1/4 moa adjustments and also is marked 0-14
The elevation adjustment is also marked 25-275 in blue. I believe this to be the adjustment for BDC in yards.
But there is also a third knob on the left side marked 10 - the infiniti sign. I think this is the side focus and is only used to make the image clear? But then why is there an adjustment on the eyepiece which i thought was for optical clarity as well?
So what I gather from this is that I should zero the rifle scope as normal at 100 yards. Then when I am done losen the elevation knob and move the 100 yard mark back to the hash mark with out adjusting my zero. Then once it is back on the 100 yd mark all i have to do is move the dial to the distance I am shooting at for a correct BDC, does this sound correct?
So what does this mean the left side "third knob" is for?
Thanks
