There's an article in the latest Shooting Illustrated comparing the accuracy/consistency/precision of large primers vs. small in cartridges where you can get brass with either a large or small primer pocket.
Here it is:
Large- or Small-Rifle Primers: Which is Better?
The author did his testing with a wildcat cartridge of his own creation. His half-assed test gave a slight advantage to the rounds loaded with large primers. This is the opposite of what I've seen.
I load three rifle calibers that are available with both small and large primer pockets (6.5 Creedmoor, 6.8 SPC, and .308) and have found the small primer versions to be better in every case, especially with the 6.8 SPC.
