28 Nosler Bertram Brass

[ShortMag3]

I purchased some Bertram brass due to the shortage of Nosler brass.
Seems like decent quality but the brass averages 20 grains lighter than the Nosler. If anyone has loaded with both I'm curious as to the affect on velocity using the same load.

Betram is usuually tougher than Nosler/Norma. It also has more vol as you have noticed.
