Starline Brass or other?

[Mad Charlie]

That's unfortunate, I've been using Starline and the primer pockets strike me as kind of weak, I was hoping Hornady might be a little better.

Not unusual in this sport for folks to seem to get different results with the same components. I was going to remark on how Starline case heads seem to be tougher than Hornady and Lapua, and to be careful working up. A load that leaves slight ejector swipes on my Lapua cases doesn't leave any marks at all on my Starline cases. The few Hornady factory loads that I have fired all have slight ejector swipes. I use a 10x loupe when examining fired cases, and my endoscope to check the inside.

I don't continue to use loads that leave ejector swipes, and I only have 7-8 firings on some of my Starline cases, but the primer pockets are still acceptable.

Good luck.
