Case resizing lubes~How to select, properly use them, and hassles to avoid

Published on April 29, 2017

This video details the critical role of case lubricants in reloading, especially for bottleneck cartridges like the 7mm-08 Remington being reformed to .243 Winchester. It compares commercial lubes like Lee and Hornady with household alternatives such as Crisco and gear oil, demonstrating that most high-viscosity lubricants can work. Proper application, avoiding over-lubrication to prevent case dents, and effective cleanup methods using dish soap are also covered.

Quick Summary

Bottleneck rifle cases require lubrication during resizing because the die works the entire case body and shoulder, generating significant friction. Over-lubrication can cause hydraulic 'case dents.' Household items like Crisco or gear oil can work, and cleanup is best done with warm water and Dawn dish soap.

Frequently Asked Questions

Why do bottleneck rifle cases require lubrication during resizing?

Bottleneck rifle cases need lubrication because the resizing die must work the entire case body and shoulder, creating significant friction. Straight-walled pistol cases, especially with carbide dies, often do not require lube.

What are some common household items that can be used as case resizing lubricants?

Effective household lubricants for case resizing include SAE 90 gear lube, Crisco shortening, Vaseline, and STP oil treatment. Any high-viscosity lubricant capable of breaking surface tension can work.

How can I avoid damaging cases during resizing due to over-lubrication?

Avoid over-lubricating, especially on the shoulder of bottleneck cases. Applying only a tiny smear is sufficient. Excessive lube can cause hydraulic pressure, leading to 'case dents' and compromising the case integrity.

What is the best way to clean lubricant off reloaded ammunition?

After reloading, wash the finished ammunition in a tub of warm water with Dawn dish detergent. This method effectively removes all types of lubricants, including grease and oil, leaving the brass clean.
