Lee Collet Die solution for 284.

#1 Postby Steve N » Sun Dec 23, 2018 3:19 pm

I recently heard that a 7x57 Lee Collet die would work on a 284.win case so I got one and tried. At first it was a fraz short and would actually bump the shoulder back but only .001". A couple of minutes with a drill to just remove a little from the neck hole in the collet and that's it. Until now I had been using a 7-08 die with a spacer washer but this is so much easier.

Lee make custom collet dies Steve. I recently got one for the 6.5 SLR.
Email them, they send you an order form.
Send it back with 2 fire formed cases and 1 of your prefered projectiles and they make the die to fit and send it back with a bullet seater as well (i don't use it either).
Just remind them on the order form not to return the cases or projectile.

Your way does actually sound much simpler, but for anyone with a problematic case this took about a month from email to receipt.

I have been using LEE custom collet dies for 8 yrs or so with no problems. I use the collet die after a short body die to re-size the case and maintain head space.
