It would be simple enough to test.

Find a rubber plug that fits a shell and drill it for an inflation needle, you know, the kind Tom Brady uses to deflate footballs. Hose clamp to open crimp.

Clamp the thing down so the primer can't blow out, and turn on the air compressor.

If it gets to 30 PSI, I would be shocked.
