You have to use large primers in large primer pockets and small primers in small primer pockets.
Do not mix the 2. If your brass has both sizes, then buy both sizes of primers.
A small primer in a large primer pocket will fall out. Trying to get a large primer into a small primer pocket may cause a slight explosion.
Many different thoughts on the accuracy question. Lapua uses small flash holes due to cold weather. Supposed to transfer a more consistant, hotter flash due to the narrow flash hole. Thus better accuracy.
More powder usually wants a bigger primer, Wolf uses large primers. Some Wolf shoots great other Wolf, not so much. Not sure of the PPU brass.
I think the flash hole and pocket size should be standardized.
