Lee Precision 7Mm Remington Magnum Full Length Sizing Die Only
$17.25
The Lee Precision 7mm Remington Magnum full-length sizing die is the workhorse of any reloader's benchful of 7mm Mag brass. Unlike neck-sizing dies that reshape only the case neck, a full-length die brings fired cases back to proper factory dimensions across the entire cartridge—neck, shoulder, and body. That matters if you're loading for multiple rifles in the same caliber or simply want the precision and repeatability that full-length sizing delivers. After firing, your cases expand to fit your rifle's chamber; a full-length sizing die restores them to spec, removes firing-induced bulges and irregularities, and sets you up for consistent, safe reloads shot after shot.
Proper setup is key to getting the most from this die. You'll clean your fired cases, install the die in your press, and adjust it gradually until the case shoulder is bumped back by roughly 0.001 inch—a small bump that ensures your cases will chamber reliably in different rifles. The process involves periodic checking every 10 cases or so to hold your shoulder bump dead on. Lubricate your brass before sizing to protect both the die and the case from unnecessary wear.
Lee Precision sizing dies are built to handle the rigors of serious volume reloading without breaking the bank. This die-only setup gives you the core tool you need; you'll supply your own press and shell holder. Pair it with a quality reloading press and the right ancillary equipment, and you'll have a straightforward path to accurate, repeatable 7mm Magnum loads for hunting or long-range shooting.

Frequently Asked Questions
Will this die work with my 7mm Rem Mag rifle?
Yes. Full-length sizing dies are suitable for any rifle chambered in 7mm Remington Magnum, regardless of manufacturer. If you have multiple 7mm Mag rifles, this die will handle brass from all of them.
What's the difference between full-length sizing and neck sizing?
A full-length sizing die reshapes the entire case—neck, shoulder, and body—returning it to factory dimensions after firing. A neck-sizing die only resizes the neck portion. Full-length sizing is more versatile and is the standard choice for rifles fired from a variety of chambers.
What do I need to use this die?
You'll need a reloading press, a shell holder for 7mm Remington Magnum cases, and fired brass to reload. This purchase includes the die only.
How often do I need to adjust the die during a reloading session?
Check your shoulder bump every 10 cases or so and adjust the die if needed to keep consistent shoulder bump—typically around 0.001 inch. Regular checks help prevent overworking brass and reduce the risk of case head separation.
