Duration: 14:09

This guide details the barrel break-in procedure recommended by Proof Research, emphasizing smoothing micro-roughness for optimal long-term accuracy and velocity. The process involves a specific sequence of shooting and cleaning, with a focus on cleaning from chamber to muzzle. While not always deemed essential for every firearm, it's recommended for precision rifles where extreme accuracy is paramount.

Quick Summary

Barrel break-in aims to smooth micro-roughness in a new rifle barrel, potentially improving long-term accuracy and velocity. Proof Research recommends a specific sequence of shooting and cleaning: three shots then clean, three more shots then clean, and finally five shots then clean. Avoid moly-coated ammunition during this process.

Frequently Asked Questions

What is the primary reason for breaking in a rifle barrel?

The primary reason for breaking in a rifle barrel is to smooth out any micro-roughness or imperfections in the bore that can occur after initial shots. This process aims to improve long-term accuracy and potentially increase projectile velocity by reducing friction.

What is Proof Research's recommended barrel break-in procedure?

Proof Research recommends shooting three shots and cleaning, followed by another three shots and cleaning, and finally five shots and cleaning. This sequence is designed to gradually seat the rifling and remove initial imperfections without over-cleaning.

Should I use moly-coated ammunition during barrel break-in?

No, Proof Research advises against using moly-coated ammunition during the break-in period. They recommend firing at least 100 rounds of standard copper-jacketed bullets before using moly-coated ammunition.

Is barrel break-in necessary for all firearms?

Barrel break-in is generally considered more critical for precision rifles intended for extreme long-range shooting where minute accuracy differences matter. For many semi-automatic firearms or general-purpose rifles, the necessity is debated, and it may not be as crucial.
