I'm using Strelok Pro with with Zan Slugs and an Impact MK2 with the Heavy Slug Liner with a 1:18 twist rate. The projectiles are .25 Zan 37 grain. It's zero'd at 50 yards.
Projectile weight: 37.05 grain
Projectile speed: 985 fps set to measured temp and humidity (Metro)
BC 0.108
Target distance: 120 yd
Scope height: 8.0 cm (first focal plane)
Angle is minimal
The app says at 120 yd, the elevation should be 2.7 MRAD but in order to get on target, I'm having to set things to 3.4.
With NSA slugs it was very close to what the app called for. Having much better luck with ZAN.
So it's a riddle....what do you think I might be doing wrong?
Note: the scope is on FX elevator rings; perhaps that's messing with things?
Thanks for the help.
