Step by step

How Reticle Plotter
Works

From entering your ballistics to a print-ready reticle map with BDC holdovers — here is exactly what happens at each step.

01

Choose your reticle

Select from 9 built-in reticle templates — MPR-V5 mil-dot stadia, Half-Mil, German #4, Air Post, Duplex, BDC Circles, BDC Auto — or build your own using the custom reticle builder. Every reticle uses a calibrated mil-based coordinate system so holdover positions are physically accurate.

02

Enter your ballistics

Open the Ballistics sheet and enter muzzle velocity (fps or m/s), bullet weight, ballistic coefficient (optional for short-range air rifle), your zero distance, and scope height above bore. Reticle Plotter supports yards and metres throughout.

03

Set your target distances

Enter the distances you want holdover marks for — for example 20,30,40,50,60,70 yards for an air rifle, or 100,200,300,400,500 for a centrefire rifle. Separate them with commas. You can mix imperial and metric.

04

Auto-plot BDC holdovers

Click Plot Drops. Reticle Plotter calculates the exact bullet drop in inches at each distance using the Pejsa ballistic model, converts to mils at that range, and places a holdover mark directly on the reticle stadia at the precise position. Marks above zero (bullet is high) appear in blue; holdovers below appear in dark red.

05

Add manual markers

Tap or click anywhere on the reticle canvas to drop a custom marker. Edit the label, colour, shape, size and opacity. Use manual markers for wind holds, known impact points from field testing, or range reference marks. Full undo/redo support.

06

Save and export

Pro users can save unlimited sessions to the cloud and reload them on any device. Export the reticle as a print-ready JPEG or SVG at your chosen physical diameter and DPI — 96, 150, 300 or 600. Circle-clip to the scope boundary or export the full canvas.

The ballistics model

Reticle Plotter uses a dual-model approach — a simple parabolic model for short-range air gun and rimfire use, and a Pejsa drag model for centrefire and long-range calculations with ballistic coefficient.

Air rifle / rimfire
Parabolic model — no BC needed. Accurate for velocities under 1,600 fps and ranges under 100 yards.
Centrefire with BC
Pejsa drag model. Enter G1 or G7 ballistic coefficient for long-range accuracy out to 1,000+ yards.
Any zero distance
Zero at 10, 20, 25, 30, 50, 100 yards — any value. The model solves for muzzle angle to match the zero.
Scope height
Enter scope height above bore in inches. Default 1.5 inches. Critical for near-zero accuracy.
Mil conversion
Drop in inches is converted to mils at each target range: mils = (drop_in × 27.78) / range_yd. This places marks at the correct stadia position for your reticle.
