.280ai sammI

[MTBULLET]

Waiting on reamer for .280AI using PTG 280AI SAMMI spec (nosler) and Nosler brass(no turn) plan on 168 gr. bergers, what diameter range "S" bushings should i order to get started?

Load one of your new Nosler cases with one of your Berger 168 VLD's, and measure the loaded case's neck diameter, then subtract 0.001". And that is your proper neck bushing size (according to Redding).

 

[Methow Packer]

Two to three thousands smaller than the loaded diameter of the neck.. Kind of hard to know w/o loading a round first but you could order bushings at either direction but kind of costly that way.

I use a .309 with Nosler brass and 168 bergers. I use the expander and it drags slightly on the way out which is how I like it.
