I received my Larry Willis, Reloading Technologies Inc. , belted magnum collet sizing die today. I’ve been wanting to get one for awhile because all of my 257 weatherby brass is tight in the chamber.
I purged most of my magnums years ago, but held onto 3. Weatherby MK V all weather 257 Weatherby, Remington 700 classic 300H&H, and a Remington 673 350 Rem Mag. This die will work for all 3.
You are supposed to use it in conjunction with your FL die. Can’t wait to give it a try.
