PPU brass loaded to Hornady specs but with a larger rifle primer? Am I safe?

[LRRPF52]

Recently purchased (last October) 80 rounds of PPU 6.5 Grendel ammo. Would the fired brass be worth reloading once or twice? I already have 20 dummies made from 7.62x39 brass & some of those red colored aluminum dummies.

You’ll have to see how the Small Rifle Primer new PPU brass does for you.

I’ve also noticed with Federal Grendel brass (SRP) that it doesn’t last many loads in a gas gun for me, but in a bolt gun, it didn’t seem to exhibit anywhere near the same wear and tear and even didn’t mind being loaded warmer.

My go-to brass is Lapua and Hornady. I don’t have any Starline so I can’t compare, but others already have here and have a lot of positive experienced to relate from what I recall.

Lapua is the king of the hill in the whole brass quality/longevity metric.
