QL Request - 28 Nosler

LifeAndLiberty · Aug 13, 2017

Thank you in advance for helping me. I am looking for QL info for three seating depths in my 28 Nosler. Here is the info:

28 Nosler
24" Barrel
Reloder 33 Powder
175gr Nosler Partitions
Winchester LR Magnum primers
Nosler brass
Max COAL for my rifle's chamber as measured using a Hornady Lock-n-load gauge: 3.467"

I was looking to have this information run for seating depths of 3.445", 3.435", and 3.425" to see a good safe starting point (and where to begin thinking about stopping) with this Reloder 33 powder.

Thanks again

At the lengths you request, the charge/velocity differential is so small as to be insignificant.
