Frequently Asked Questions

Why is slugging a rifle barrel important?

Slugging a rifle barrel is important to accurately determine its exact bore diameter. This measurement is crucial for selecting the correct bullet size, especially for cast bullets, ensuring optimal fit and maximizing rifle accuracy.

What materials are needed to slug a rifle barrel?

You'll need soft lead round balls (appropriate caliber), a lubricant like Rem Oil or Break-Free for the bore, a soft liquid case lube for the slug, a cleaning rod, sections of dowel rod, a soft mallet, and digital calipers for measurement.

How do you properly prepare the barrel and slug for the process?

Generously coat the inside of the rifle bore with oil to prevent sticking. Then, lubricate the soft lead ball itself with a liquid case lube like Lee or RCBS before inserting it into the muzzle.

What is the correct technique for driving the slug through the barrel?

Secure the rifle vertically. Start the lubricated slug into the muzzle with a soft mallet. Use stacked sections of dowel rod, hammering them incrementally to push the slug completely through the bore until it exits the breech end.
