This guide details a technique for improving .22LR accuracy by sorting ammunition based on rim thickness using dial calipers and a specialized comparator. The video demonstrates how variations in primer charge rim thickness can affect ignition consistency. Testing with a CZ 457 Varmint Chassis and Vortex Razor HD Gen II scope reveals that while some bulk ammunition shows minimal impact, high-end match-grade rounds like Eley Match can see significant accuracy degradation from unsorted rims. This experimental approach, presented with high authority, offers practical insights for precision rimfire shooters seeking to maximize their rifle's potential.

Frequently Asked Questions

How does rim thickness affect .22LR accuracy?

Rim thickness variations in .22LR ammunition can impact ignition consistency. A thicker rim around the primer charge can lead to uneven ignition, potentially causing flyers and larger group sizes, especially noticeable with match-grade ammunition.
