Flash hole size in the 45 ACP I have here:
Cases from Starline, S&B, FC 98 and Aguila have a 5/64 flash hole with large primer pockets.
The Win NT have the same 5/64 flash hole and small primer pockets.
Speer and Federal have a 3/32 flash hole and large primer pockets.
...and one stamped ICC has a small primer pocket but the larger 3/32 flash hole. I don't have the Federal small primer pocket cases to check, but the flash hole doesn't seem to correspond with primer size.
5/64 = .078125
3/32 = .093750
Remington in 357 and 9mm have small primer pockets and small flash hole.
