Primer Question

[Alstep]

I have some Winchester primers, marked "#115 staynless primers". They are the large size. My question is, are they rifle or pistol?
Another question about Remington primers; what's the difference between #1 1/2 and #5 1/2 small pistol primers?

The Remington 5-1/2 was a heavy cup primer for the 357 Magnum with cup of 0.018"base metal thickess vs. 0.015" for regular small pistol or 0.020".for the military .30 carbine or 9mm NATO primer, which would ompare to the Remington 6-1/2 small rifle. The heavy cup 5.56mm primer is 0.025" cup thickness.
