Neck sizing

[Kgkimerer]

257 Weatherby, first time with a belted magnum. Chambered ina Ruger No.1. Neck or full length sizing?

Try just neck sizing and see if they chamber. They probably will until the neck grows enough to fill the chamber might take a firing or two

 

[Rich Coyle]

From my experience neck sizing produces slightly more velocity and slightly better groups. Just have 2 run in each round through the chamber before going hunting.

FL, a #1 has no camming action , like a bolt action. Use a comparitor to gauge amount of sizing needed.

Set your FL die up with a comparator to bump the shoulders back .002
