BC TOOLKIT

Ballistic calculators

Four BC/POI/V2 calculators with built-in G1 / G7 / GA / GS ballistic tables.

BC001

BC calculator

Calculates ballistic coefficient (BC) from two measured velocities, V1 and V2, and the distance between the chronograph positions.

BC002

Ballistic calculator

Calculates downrange velocity V2 at D2 from velocity V1 measured at D1 and the selected ballistic coefficient (BC).

BC003

BC calculator — V1 and POI

Calculates ballistic coefficient (BC) from muzzle velocity V1 and a measured point of impact (POI) at a known range.

BC004

Ballistic calculator — Kill Zone

Extended ballistic calculator that also determines the kill-zone range window from V1, D1 and BC.

Related tool

BC001–BC004 reports saved from the calculators above can be loaded into the Scope Reticle (RETICLES) tool to plot the impact points on the reticle grid.
