Duration: 6:47

This guide details a professional method for breaking in a new factory rifle barrel and zeroing a scope, as demonstrated by Mike Davidson of Gunwerks. It covers a systematic fire-and-clean procedure for barrel conditioning, followed by precise range testing at 100 yards, calculating MOA adjustments, and physically zeroing the scope turrets for optimal long-range accuracy. The process emphasizes meticulous measurement and adjustment for sub-MOA performance.

Quick Summary

Expert guidance from Gunwerks' Mike Davidson details a factory rifle barrel break-in process using a fire-and-clean method over 20 rounds. It covers precise 100-yard zeroing by measuring impact, calculating MOA adjustments (e.g., 1/4 MOA clicks), and physically resetting turrets to zero for future long-range shooting.

Frequently Asked Questions

What is the recommended procedure for breaking in a new factory rifle barrel?

Mike Davidson of Gunwerks recommends a break-in process involving firing three rounds, followed by thorough cleaning to remove copper fouling. This cycle should be repeated for approximately 20 rounds (one box of ammunition) to condition the barrel for optimal accuracy.

How do you calculate scope adjustments for a 100-yard zero?

At 100 yards, measure the deviation from the bullseye in inches and convert it to MOA (1 inch = 1 MOA). Then, divide the total MOA adjustment needed by the scope's click value (e.g., 1/4 MOA) to determine the number of clicks required (e.g., 2 MOA down needs 8 clicks of 1/4 MOA).

What is the purpose of zeroing scope turrets?

Zeroing the scope turrets involves physically resetting the turret cap to the '0' mark after achieving a confirmed zero. This allows for easy reference and ensures that when you dial for distance, you are starting from a known baseline, crucial for creating custom ballistic turrets.

What accuracy was achieved with the factory rifle after break-in?

After the break-in procedure and zeroing, the factory rifle achieved sub-MOA accuracy, with groups measuring approximately 3/4 to 7/8 of an inch at 100 yards, indicating good performance.
