RIFLE FACTORY CRIMP DIES Reviews & Ratings

Lee 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
Features a collet that squeezes the case mouth into the crimping groove for a firm hold
Shellholder not included
Fits all 7/8"-14 thread reloading presses

NOTE: 338 Lapua Magnum fits reloading presses with 1-1/4" -12 threads.

Great

I have a number of Lee Factory Crimp dies and have been happy with the results. I can't seem to tell a difference in accuracy or SDs, but for the price, its good insurance when you're at max loads and you don't want the bullets moving around in the case when you're firing from an AR.

Works as intended

Improves ballistic uniformity, provides its own crimping cannelure when there isn’t one, and it’s fast & easy to use. What’s not to like?

Useful tool

I use these for all my rifle cartridges. it produces a uniform crimp even if lengths are not exactly the same. Still a good idea to use same recommended trim lengths.

Have several

Easy to adjust and its about impossible to crush a case

On its way

I'm a collecter of lever action Winchester and Henry rifles, collect but shoot also. Have not had any issues with Lee in the crimp or seating dies area so expect no issues with this one either.

What I expected

The shipping time was a valuble plus, I'd set in for a long wait but the folks at Brownells kept me up to date and the purchase was delived on the second day after order confirm. Thanks folks, I sent two more orders .... for now Derrick
