Lee 7mm Backcountry Micrometer Full Length Die Set includes a Full Length Sizing Die, Micrometer Bullet Seating Die, Universal Shell Holder, Powder Dipper and Instructions/Load Data. Select this die set if you are reloading mixed range brass.
Special note: steel cases require substantial effort to full length resize. Be sure you’re using ample, high performance case lubricant like our Lee Resizing Lubricant. When sizing, once the effort becomes extreme, remove the case and redistribute the lubricant, re-insert the case and size to completion.
If you will be reloading for hunting, or your firearm magazine limits the overall length and prevents your bullet from touching the rifling, we recommend restoring accuracy with the accessory Lee Factory Crimp die.

Lee 7mm Backcountry Factory Crimp Die crimps the bullet in place more firmly than any other tool. Tests demonstrate that even bullets which have no crimp groove will shoot more accurately. A firm crimp improves accuracy because pressure must build to a higher level before the bullet begins to move. This higher start pressure insures a more uniform pressure curve and less velocity variation.
