Manufacturer-published inputs

Item numbers, bullet descriptions and weights, muzzle velocity, muzzle energy, G1/G7 coefficients, and test-barrel length come from the linked manufacturer source.

CaliberAtlas-modeled outputs

Drop, retained velocity, calculated retained energy, wind drift, and time of flight are CaliberAtlas G7 point-mass results, not manufacturer-published trajectories.

Conditions: 59°F · 29.92 inHg · sea level · 50% RH · 1.5″ sight height · 200 yd zero · 10 mph full-value crosswind · 100 yd steps through 1,000 yd.

Your rifle, barrel, ammunition lot, and field conditions will differ. Confirm predictions at the range before relying on them.

Pick 7mm PRC if…
