6.5 Grendal vs 6ARC Brass

[corpsman8483]

I had weight differences, quit using resized Grendel brass and only use Starline 6ARC brass now. Seems that when I resized the 6.5 Grendel and trimmed to length I had necks that were a little thicker (>0.001") and that affected neck tension and it's ability to chamber.
