Flattest-Shooting Cartridges Ever

Published on August 9, 2021
Duration: 8:50

This video provides an expert analysis of the flattest-shooting rifle cartridges, challenging common perceptions with data-driven insights. The host, Jim Harmer, leverages a comprehensive database of 82 centerfire cartridges to rank them by bullet drop at 600 and 1,000 yards. He highlights the superior performance of cartridges like the 6.5-300 Weatherby Magnum, 26 Nosler, and 28 Nosler, while also discussing the surprising capabilities of the 22 Creedmoor. The explanation delves into the physics of external ballistics, using analogies to illustrate how bullet weight and ballistic coefficient affect trajectory at different ranges. The host also showcases his Tikka Wilderness rifle in 6.5 PRC as a practical example of a high-performing hunting rifle.

Quick Summary

Expert analysis using a database of 82 cartridges reveals the 6.5-300 Weatherby Magnum, 26 Nosler, and 28 Nosler as top performers for flat trajectory at 1,000 yards. Lighter bullets may excel at shorter ranges, but heavier bullets with high ballistic coefficients maintain velocity better over extreme distances, impacting overall bullet drop.

Frequently Asked Questions

What are the flattest-shooting rifle cartridges according to expert data?

Based on extensive data analysis, the 6.5-300 Weatherby Magnum, 26 Nosler, and 28 Nosler are among the flattest-shooting cartridges, particularly excelling in 1,000-yard bullet drop comparisons. The 22 Creedmoor also shows surprising performance.

How does bullet weight and ballistic coefficient affect trajectory?

Heavier bullets with higher ballistic coefficients (like baseballs) tend to retain velocity better at extreme ranges, resulting in a flatter trajectory compared to lighter, faster bullets (like pebbles) which may drop more significantly over longer distances.

What factors influence a cartridge's 'flatness'?

While inherent cartridge design is key, factors like specific ammunition loads, barrel length, and the rifle platform itself can significantly impact a cartridge's real-world trajectory and perceived 'flatness'.

Which rifle was showcased for its ballistic performance?

The host showcased a Tikka Wilderness rifle chambered in 6.5 PRC, highlighting its impressive ballistics and suitability for hunting applications where flat trajectory is advantageous.
