Description
L.E. Wilson has been machining precision reloading tools for right around 90 years, and this bushing-type full length die for the 7mm Remington SAUM carries that reputation. In a single stroke it sizes the case body and bumps the shoulder back to standard dimensions while an interchangeable bushing handles neck tension. That means you get the reliable chambering of a full length sizer with the fine-tuned neck control that precision loaders usually chase with a separate neck die.
How the 7mm SAUM Bushing Full Length Die Works
The big difference between this and a conventional full length die is that there's no expander ball dragging back through the case neck. Instead, the bushing sizes the outside of the neck to a diameter you choose, which cuts down on the brass stress that shortens case life and tends to leave your necks running truer. The die includes an adjustable depth decapping rod so you can set pin depth for clean, consistent primer removal, and Wilson throws in a spare decapping punch. It also runs without a bushing installed if you ever just want a body die to push the shoulder back.
Picking Bushings for Your 7mm SAUM Loads
Bushings are sold separately, which is standard for this style of die since the right size depends on your brass and bullet. The quick method most handloaders use is to measure the neck diameter of a loaded round and subtract about .002 to .003 inches for proper tension. Wilson recommends their own neck sizing bushings, though Redding bushings will also drop into this die if you already own a set. Keeping a couple of sizes on hand lets you tune neck grip for different bullets, brass lots, or conditions.
Built to Wilson Standards
This die is made from heat-treated steel hardened to L.E. Wilson spec, tougher than a Grade 8 bolt, so it holds its dimensions through years of use. It threads into any standard 7/8-14 reloading press and pairs well with a Wilson case gage to check your shoulder bump and keep from overworking the brass. For anyone loading the 7mm SAUM for accuracy, this is the kind of tool that earns its spot on the bench.

Frequently Asked Questions
Does the 7mm SAUM bushing full length die come with a bushing?
No, bushings are sold separately with this die, which is normal for the bushing style since the correct size depends on your brass and bullet combination. Wilson recommends their own neck sizing bushings, though Redding bushings will also fit this die body. Most loaders keep a couple of sizes on hand to fine-tune neck tension.
How do I pick the right bushing size for my 7mm SAUM?
The simplest method is to measure the outside neck diameter of a loaded round with a micrometer, then subtract about .002 to .003 inches for your desired neck tension. That accounts for brass spring-back and gives you a secure bullet grip without overworking the neck. Wilson includes the full formula in the instruction sheet that comes with the die.
Will this die fit a standard reloading press?
Yes, it threads into any standard 7/8-14 reloading press, so it works in the common single-stage presses most handloaders already run. It also pairs nicely with a Wilson case gage to verify your shoulder bump.
Can I use this die without a bushing installed?
You can. With the bushing removed, the die will size just the case body and push the shoulder back, effectively working as a body die. That gives you a little extra versatility when you only need to work the body and not the neck.
