Unveiling the Mysteries of Rimfire Research

🔬Rimfire shooting presents unique challenges at long ranges due to sensitivities and finickiness of 22 rimfire ammunition.

🎯Hitting targets at 200, 300, or 400 yards with 22 rimfire requires a deep understanding of ballistics and stability.

🌬️The aerodynamics of subsonic projectiles, like 22 rimfire, differ from supersonic projectiles, such as center fire, leading to stability challenges.

📈Conventional ballistic coefficients (BC) for 22 rimfire do not accurately represent the subsonic drag model of the bullet, requiring new standards or Doppler radar profiles.

💨Mock trimming, where half of the shots are trimmed due to higher velocity, reduces vertical dispersion at long range but increases wind deflection.

Why is Rimfire shooting more challenging at longer ranges?

—The sensitivities and finickiness of 22 rimfire ammunition, combined with the unique aerodynamics and stability of subsonic projectiles, make hitting targets at longer ranges more challenging.

Why do conventional ballistic coefficients not accurately represent 22 rimfire?

—The drag models and aerodynamics of subsonic projectiles, like 22 rimfire, differ significantly from supersonic projectiles, such as center fire, leading to the need for new standards or Doppler radar profiles.

What is mock trimming?

—Mock trimming refers to a phenomenon where half of the shots fired have their velocity trimmed due to being close to or above the speed of sound. This can result in reduced vertical dispersion at long range but increased wind deflection.

Why is understanding stability important in Rimfire shooting?

—Stability plays a crucial role in the accuracy and consistency of Rimfire shooting, especially at longer ranges. The unique aerodynamics and stability challenges of subsonic projectiles require a deeper understanding for better results.

How can Rimfire shooters improve their performance at long range?

—By understanding the complexities of Rimfire ballistics, trajectories, and stability, shooters can make more informed decisions regarding ammunition, muzzle velocity, and temperature effects to optimize their performance at long range.
