A friend ask for help reloading this brass. I discovered that the ID of the primer hole is 0.200 and the OD of CCCI 500 and Federal 100 primers is 0.190. That is 10 thousands difference. Is there a primer to fit the S & B 0.200 hole?

Looks like a job for someone with a primer pocket reamer.

The primer pocket is .010 greater than the primer.

Primer pocket dimensions and tolerances:
Small Pistol: Diameter Min = 0.1730, Diameter Max = 0.1745
Large Pistol: Diameter Min = 0.2085, Diameter Max = 0.2100

I measured a small rifle primer, they are the same size as the small pistol primers, and it measured 0.175. If the primer pocket is already @ 0.200 then you have to ream out the pockets to large pistol size and use large pistol primers.

What are you using to measure the primers and primer pockets?

something changed, S&B used to have uuber tight primer pockets.
is the flash hole oversized by chance?

In my experience... S&B primer pockets were always SMALL and their brand primers were always oversized. I throw S&B 45acp cases away and I don't use S&B primer in the progressive press.

Your findings are opposite of what I've seen over the years. I'm going to mic the S&B primers that i have now.

yes it is over sized(0.200). I am measuring with a very good set of Vernier calipers. I am a machinist, know how to measure a primer pocket.

It sounds like you have under sized large pistol primer pockets.

These primer pockets are nowhere near a large primer ID.

I tried a W-W non toxic case with small primer pocket with Federal 100 small pistol primer which fits perfectly, therefore the Selliotte and Boleh cases must have had a crimped small pistol primer that came off with primer when we de-capped the primers.
Please excuse my spelling of S & B.
