Strelok: Ballistic Calculator
Trajectory & Holdover Charts
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Strelok Pro is a ballistic calculator trusted by long-range shooters and hunters. 4,000+ bullets, atmospheric corrections, MOA/MRAD solutions, and dope cards.
Strelok Pro is a ballistic calculator that helps long-range shooters, hunters, and precision rifle competitors compute accurate firing solutions for any rifle, cartridge, and atmospheric condition.
WHO USES STRELOK PRO?
Long-range and ELR shooters calculating trajectory data from 100 yards to beyond 2 miles. Hunters who need quick field holdovers adjusted for altitude, temperature, and shot angle. Competition shooters building detailed dope cards and truing ballistic data against observed impacts.
WHAT DOES STRELOK PRO CALCULATE?
Strelok Pro solves the point-mass ballistic equation using G1, G7, and custom drag models. It computes elevation and windage corrections accounting for atmospheric conditions (temperature, pressure, humidity, density altitude), Coriolis and Eötvös effects, spin drift and aerodynamic jump, powder temperature velocity sensitivity, shot angle cosine correction, and multi-segment wind modeling with variable speeds and directions. Solutions are delivered in MOA, MRAD, inches, centimeters, or scope clicks.
HOW LARGE IS THE DATABASE?
Over 4,000 bullets with manufacturer ballistic coefficients. A comprehensive cartridge and factory ammunition library. 200+ reticle models from Vortex, Nightforce, Leupold, Schmidt & Bender, and more. Scope profiles with click-value calibration.
WHAT FIELD TOOLS ARE INCLUDED?
Interactive scope reticle view with computed holdovers at each hash mark. BC and muzzle velocity truing from observed impacts. Moving target lead calculator. Maximum point-blank range (MPBR) calculator. Quick-reference dope cards. Full trajectory tables with customizable range intervals.
From confirming zero at 100 yards to computing solutions for 2-mile ELR shots, Strelok Pro delivers firing data that matches real-world conditions.
