CEP Shooting: The Smart Way to Grade Your Groups

CEP shooting explained: R50, R95, and why pooling small groups beats grading a rifle by its two widest shots. Honest, simple statistics.

How often to clean a rifle barrel? No universal round count. Carbon vs copper, fouling shots, and building an interval from your data.

Suppressor POI shift explained: why a can moves your impacts, how to measure it fairly, and why suppressed and bare data stay apart.

Barrel tuner testing done right: one load, stepped tuner positions, enough shots per step, and how to tell a real effect from noise.

How to true a ballistic calculator in the right order: fix the inputs, verify tracking, true velocity first, then drop. Never both at once.

Cold bore shift explained: what really moves the first round, why most of it is fouling or noise, and how much data proves it is real.

How to level a rifle scope properly: reticle cant, ring torque, plumb line method, and the tall target test that proves it worked.

How many shots for load development? The statistics behind why 3-shot groups mislead, and what sample size actually proves a difference.

Spin drift and Coriolis demystified: how far each really moves your bullet at 1000+ yards, which direction, and when they actually matter.

How to build a DOPE card step by step: what DOPE means, using a ballistic calculator, truing muzzle velocity, and validating drops on steel.
