Lee Collet Lee 90926 Collect Crimp Die 460 S&w

The Lee Precision 90926 collet crimp die for .460 S&W Magnum is purpose-built for handloaders who demand precision and case longevity. Unlike conventional sizing methods, this collet crimp die uses a precision mandrel and collet mechanism to squeeze the case neck to a perfect fit with minimal run-out—ideal if you're loading for a magnum revolver and want repeatable, tight tolerances shot after shot. Because the collet system requires no case lube, you'll spend less time prepping brass and more time at the range.

The real value of a collet crimp die shows up over time. By sizing only the neck and preserving the fire-formed body of your brass, cases remain in service far longer than with full-length sizing. That means the investment in this die pays for itself quickly if you're working with even a modest volume of .460 S&W Magnum brass. If you're serious about handloading for a big-bore revolver, this die will help you get the most out of every piece of brass you fire.

For best accuracy, seat your bullets to touch or nearly touch the rifling in your barrel. As always, only reload cases that have been fired in your own firearm to ensure consistent chamber fit and safe pressures.

Frequently Asked Questions

What is a collet crimp die and how does it differ from standard handgun dies?

A collet crimp die uses a collet to squeeze the case neck against a precision mandrel, creating a tight, consistent fit with minimal run-out. This neck-sizing-only approach preserves the fire-formed body of your brass, extending case life significantly compared to full-length sizing dies.

Do I need to use case lube with this die?

No. The collet crimp die does not require case lube, which simplifies prep work and reduces mess during the reloading process.

How much longer will my .460 S&W Magnum brass last with this die?

Cases loaded with a collet crimp die last approximately ten times longer than those sized with conventional methods, since only the neck is sized and the fire-formed body is preserved.

Can I use this die on brass fired in other firearms?

No. Only reload cases that have been fired in your own gun to ensure consistent chamber fit and safe pressures.
