Range Ready Tip: New Dies & Case Lube | Gun Talk

Duration: 1:41

This guide from Ultimate Reloader demonstrates the critical first step when using brand new rifle reloading dies: priming the die. By applying a small amount of oil to a case and running it through the new die, you create an initial layer of lubrication. This prevents the 'worst-case friction scenario' and significantly reduces the risk of stuck cases, especially with challenging cartridges like the .223 Remington.

Quick Summary

Priming new rifle reloading dies is essential to prevent stuck cases. Apply a small amount of gun oil or synthetic motor oil to a case and run it through the new die before regular use. This creates initial lubricity, especially important for challenging cartridges like the .223 Remington, allowing for smoother resizing with less aggressive lubricants afterward.

Frequently Asked Questions

Why is it important to prime a new rifle reloading die?

Priming a new rifle reloading die is crucial to prevent the 'worst-case friction scenario.' Applying a small amount of oil to a case before the first use creates an initial layer of lubrication, significantly reducing the risk of stuck cases, especially with challenging cartridges like the .223 Remington.

What is the best way to prime a new sizing die?

To prime a new sizing die, thoroughly clean it first. Then, apply a very small residue of gun oil or synthetic motor oil to the outside of a case and run that case up into the die. This primes the die with sufficient lubricity for initial use.

What lubricants can be used after priming a new die?

Once a new die has been primed, you can often get away with using less aggressive lubricants like spray-on case lube. Alternatively, products with high lubricity, such as Imperial Case Sizing Wax, are also good options for subsequent resizing tasks.

Are certain rifle cartridges more prone to stuck cases?

Yes, cartridges like the .223 Remington are more prone to stuck cases due to their high surface area and small case rim. Proper lubrication and die priming are essential for these calibers to avoid resizing issues.
