Frequently Asked Questions

How can I fix a sticky chamber in my 22 Nosler?

A common method to address a sticky chamber is to polish the chamber area. This can be done using a mildly abrasive compound like JB Bore Paste applied to a snug-fitting mop head and then run with a drill for about a minute. Thorough cleaning afterward is crucial to remove all residue.

What are the potential issues with bulk-purchased reloading brass?

Bulk-purchased reloading brass, especially if labeled 'unprepped,' may not be weight-sorted, have un-deburred flash holes, or un-chamfered case mouths. These inconsistencies can affect reloading accuracy and firearm function, unlike smaller packs that are often prepped.

What is a cost-effective way to diagnose a faulty barrel?

If you suspect a barrel is faulty, a cost-effective diagnostic step is to purchase an inexpensive replacement barrel from a reputable retailer like MidwayUSA. For example, an AR Stoner barrel can be acquired for around $140 to test if the issue persists with a new barrel.

Which bullet is recommended for improving accuracy in the 22 Nosler?

For the 22 Nosler, the 69-grain Sierra MatchKing bullet is highly recommended by experienced reloaders for its potential to deliver smaller groups and better overall accuracy. It's often paired with powders like Varget for optimal performance.
