This guide details a deep cleaning process for bolt-action rifles experiencing accuracy degradation, inspired by Ron Spomer's insights. It covers identifying the problem, understanding the theory behind cleaning for different bullet types, performing a baseline test, executing a thorough cleaning with specific tools like a borescope, and re-testing for improved accuracy. The process emphasizes removing all fouling to restore sub-MOA performance.

Quick Summary

Restore your Sako 90 Quest rifle's accuracy by addressing barrel fouling. Expert Ron Spomer advises that switching to all-copper bullets after using lead may require a deep clean to bare metal. A baseline test, thorough cleaning with SC14 and a borescope, and re-testing can restore sub-MOA performance, with tested groups improving from 1.4 inches to 0.64 inches.

Frequently Asked Questions

What causes a rifle like the Sako 90 Quest to suddenly lose accuracy?

A common cause for sudden accuracy loss in rifles like the Sako 90 Quest is barrel fouling. If you switch from lead-based bullets to all-copper bullets, or if significant fouling builds up, it can prevent the bullet from sealing the bore properly, leading to larger group sizes.

How can I restore accuracy to my rifle if I suspect fouling issues?

According to expert advice, a deep cleaning process is often necessary. This involves using specialized solvents like SC14 Gun Cleaner and potentially a borescope to ensure all copper and lead fouling is removed down to the bare steel of the barrel.

What is the accuracy potential of the Sako 90 Quest rifle?

The Sako 90 Quest rifle is known for its high accuracy potential. When properly maintained and cleaned, it is capable of sub-MOA performance, with tested average group sizes as small as 0.64 inches.

What is the role of Ron Spomer's advice in rifle cleaning?

Ron Spomer's expertise highlights the critical difference in cleaning requirements when using all-copper bullets versus traditional lead or gilding metal jacketed bullets. His advice emphasizes that achieving optimal accuracy with copper bullets often necessitates a more rigorous cleaning to bare metal.
