Mil-Ranging Calculator
Estimate distance to a target of known size from how big it appears in your reticle. Enter the target's real size and how many mils (or MOA) it subtends for width or height — the solver returns the range. Example: a 20" target that appears 1 MIL tall is ~556 yds / 508 m.
Common Target Sizes

Zero Assistant
Select your rifle and projectile, enter the distance you are zeroing at, then click on the target to mark where each shot landed. The assistant averages your group and gives the scope correction (elevation & windage) to move your point of impact to center.
MIL per click
Tip: selecting a saved rifle/projectile profile ensures the correction matches the gun & load you are zeroing.
Click the target to mark each shot. Each grid square = 1". The bullseye (center) is your point of aim.
Truing Calculator ⓘ What is truing?
Tip: calculate a solution first (with Truing at 1.0) so the predicted elevation auto-fills. Then enter the elevation you actually dialed and click Calculate.
Barrel Temperature MV Offsets
Set MV offsets for barrel condition. Offsets are relative to the base MV (e.g., cold bore = -15 fps means MV is reduced by 15 fps on a cold barrel).
Advanced Ballistics
Advanced solver parameters for fine-tuning trajectory calculations.
1.0 = no truing applied

Wind
Combined Wind and Wind Hold show the direction to dial/hold (turret or reticle). Spin Drift and Coriolis show the bullet's physical drift. A 3 o'clock wind blows right→left, so you hold right.
