22 Nosler - Part 6 - Extra Heavy Buffer

Published on November 8, 2017
Duration: 20:10

This video details troubleshooting persistent brass extraction issues with the 22 Nosler cartridge. The presenter explores the use of an extremely heavy buffer (nearly 8.5 ounces) and an extra-power spring in an attempt to mitigate brass damage, including bent rims and burrs. Extensive gas block tuning was performed, but the brass issues persisted across various settings. The presenter concludes that the 22 Nosler, in this configuration, is problematic and suggests alternative cartridges like the 6.8 SPC or 224 Valkyrie for those experiencing similar difficulties.

Quick Summary

Persistent brass extraction issues with the 22 Nosler, including bent rims and burrs, were tested with an extra-heavy buffer (8.375 oz) and an extra-power spring. Despite extensive gas block tuning, the problems persisted, suggesting potential inherent challenges with the cartridge in certain configurations.

Frequently Asked Questions

What are the common brass extraction problems encountered with the 22 Nosler?

Users often experience primers falling out, bent rims, and significant burrs on the case rim where the extractor engages. These issues can occur even with light loads, indicating potential design or manufacturing challenges with the cartridge or associated firearm components.

How does an extra-heavy buffer potentially help with extraction issues?

An extra-heavy buffer increases the mass of the bolt carrier group. This increased mass slows down the rearward movement of the bolt after firing, theoretically allowing the case to contract slightly and release from the chamber more easily before extraction begins, reducing stress on the brass.

What is the weight of the extra-heavy buffer tested in the video?

The extra-heavy buffer tested weighed 8 and 3/8 ounces, which is approximately 8.375 ounces. This is significantly heavier than a standard carbine buffer (3 ounces) and even a rifle buffer (5 ounces).

What alternative cartridges are suggested for users experiencing 22 Nosler brass issues?

For those facing persistent brass extraction problems with the 22 Nosler, the presenter suggests considering the 6.8 SPC cartridge, potentially with a 6.8 SPC bolt, or exploring the upcoming 224 Valkyrie. These alternatives are known to have more established support and potentially fewer inherent issues.
