BALLISTICS & TACTICAL INTELLIGENCE
Adjust wind velocity and angle to preview dynamic Point of Impact (POI) shift:
Calculate bullet momentum and verify your official IPSC Power Factor rating:
Convert scope click measurements (MOA/MRAD) and target sizes instantly:
Calculate the exact distance between your barrel center axis and your optic center axis (critical for ballistic apps):
Calculate the physical free recoil energy and velocity of your firearm setup. Important for evaluating weapon control and hunting configurations:
Convert your ammunition Ballistic Coefficient between G1 (flat-base) and G7 (boat-tail) drag models:

Written by Marcus Vance, retired marksman & field consultant. No corporate talk, just cold physics from the firing line:
Don't trust the ammo box charts blindly. Gravity pulls every projectile at 9.8m/s虏, but drag is what ruins your day. If you plug a G1 BC into a long-range boat-tail calculation, your dope card will be off by yards at the 500-meter line. Keep your velocity readings fresh鈥攁mbient temperature swings of 20 degrees can shift your powder burn rates enough to cause major vertical stringing on target.
Free recoil is math; felt recoil is pain. A lightweight carbon hunting rig chambered in 300 Win Mag will kick like a mule, potentially leading to a nasty case of scope bite if your cheek weld is loose. If you build a rifle for a novice shooter, focus on adding mass to the chassis or mounting a highly efficient muzzle brake rather than just relying on soft rubber butt-pads.
