Negative effects of 308 lapua PALMA brass

[Midnightmedic]

Photo says it all. My son's 308 with 175gr Barnes LRX on top of cfe223 and cci450. High temp that day was 5degrees and gun/ammo in that weather for 8 hours. Oh, that was a single cold bore shot at 500 yards on his cow elk.

How much more pressure will a Small Primer case handle vs a large primer case??? 2000PSI 10,000PSI Or what?

Enough to make it to the next node, in my experience anyways.

Trevor,

If your firing pin spring is at normal power (or even better, on the strong side), there doesn't seem to be much downside to them. However, for a while, I had a weak-ish firing pin spring, and on a couple of cool days, I had some hang fires. Including one on a cool morning at the 800 yard line of the Palma individual match a couple years ago. (Thankfully, it was on the 800 yard line and not the 1000, and I was still pointing at the middle after what seemed like an hour between the click and the bang.)

I didn't notice enough (or really, any) benefit from them to take the risk of the hangfires when shooting the 155s, but the little bit I played with the 200 Hybrids, the small primer brass seemed to work very well. (And that mirrors what I've heard from the British Match Rifle shooters--the SR brass gives a nice advantage with the heavies.)

Thanks Nate.
