Small Pistol Primer on the top Large Pistol on the bottom. The inside diameter of the small pocket is 0.175" and the large is 0.208

Thanks !!!

So then the hole size through which the primer charge ignites the powder plays no part in determining what size pistol primer to use, I guess?
You would have to deprime each case to determine what size primer is needed for that individual case?
Or is there some way to determine that without depriming first.

I have found Some of the primers in the case can be easily seen as being large and others as small and then some not so easily determined.
