Is there an advantage?

I'm looking at buying some new 308W brass. Im seeing standard LR primer and SR primer cases. The SR are marked as match. Is there an advantage to the small primer vs large? Seems like ignition would suffer with the smaller primers.

I have and use both small and large primer Lapua. Just me, but I cannot say accuracy is different between them using the same load. The Palma is slower by a touch, but that is it.

I have had loose primer pockets on the standard Lapua 308 after many firings, but that Palma brass is not going to quit.

On my first 100 pieces of Palma, I had at least 5 firings as 308, then converted it to 6.5 Creedmoor (long before Lapua made SR Creedmoor brass). I have at least 10 firings on it converted before I moved away from the Creedmoor. My Creedmoor has an Obermeyer barrel I don't want to waste as it can't be replaced (call it silly or nostalgic). My hair isn't long enough for a man bun so I will need to retire and grow my hair out before I rebarrel it with a CRB in 6.5 Creedmoor....

Small pockets could allow more meat in the webs.
Small primers do not ignite less than large.
So no downside to using small pockets.
