palma brass (srp)/ pressure?

[22BRGUY]

Was wondering if Palma (small rifle primer) brass allows higher pressure loads to be used without enlarging primer pockets or otherwise cutting the life of brass that much better than standard large rife primer brass does? This would apply mostly to those shooters using .308 Palma brass.
Thanks all for replies.

yes

Thanks for reply Seymour. Any rough idea of how many more psi a guy could safely run? or maybe a rough percentage?

You expect to run top end of normal pressures with increased number of firings before primer pocket expansion. You will still open the pockets with ONE OVER-PRESSURE LOAD. So no free lunch.

Over pressure will still present itself with extractor rubs and sticky bolts, even in custom barrel/action combos. I go about 12-13 firings using 46.5 - 47 grains Varget and 155s annealing necks every fourth firing or so. Using Lapua large rifle primers with similar velocities (using Russian primers my powder charges with LRPs is a couple tenths less) I am seeing 8-10 firings before pockets go. FWIW, the ES and SD numbers with the small rifle primers are significantly better but truthfully my elevations at 1000 don't seem to know the difference at my level of shooting.
I was somewhat concerned over being able to find enough small rifle primers but at the moment there seem to be enough to go around.

Thanks much again guys and as I expected....no free lunch.

When the primer pockets get a tad loose, switch to wolf/tula

Good thought Seymour...Thanks
