Questions & Answers
Do you have an "M" die for a 7mm-08 ? Expert Answer

Yes, you can use product code LY-R6-NECKEXPDIE-7349011.

by Tiffany S., Gear Expert, August 9, 2019
Does this just flare the top of the case or does it expand the neck all the way down? Expert Answer

A bit of both. There are two steps to it. The first step expands the inside of the full case neck to just under bullet diameter for precise case neck tension in the finished reload.
The second step expands the case mouth to bullet diameter or slightly over. This allows the jacketed or cast bullet to be started perfectly centered in the case mouth and properly aligned with the axis of the case neck.

Lyman M dies by Simon Peirce, September 11, 2014
I have commenced loading hard cast polymer coated projectiles in .243 and .308, using standard dies was an issue as the gas check would enter easily but the standard belled case mouth would 'shave' the projectile. The M die has eliminated 'shaving th...

Lyman Neck Expanding Rifle "M" Die by ozdude, March 5, 2015
Great die though disappointed by the new lock rings Lyman now supplies. The old ones were were fine, these new ones with the grub screw that tightens onto the threads are not an improvement but just a cost cutting measure.

Lyman M Die for .308 by Hobbyman, Verified Owner, April 25, 2016
Great die to have if you cast bullets. It is recommended to use if you have a bullet feeder, it flares the neck allowing for a better seating when dropped by the feeder eliminating excess shaving of the projectiles.

Lyman M die for 22 Hornet by Caliboose, January 27, 2017
I used one like this at my friends house and knew I would have to order one. It is the sure way to start a bullet properly aligned in the thin neck of the Hornet! Or to start a lead bullet in larger caliber brass, use the proper Lyman M die.
