I tell this against myself!!
Last phase of much reloading of late is some 454 Casull. Got dies all set and powder measure fine tuned and off we went.
Had put out 20 Large Pistol mag primers and wondered why when after resizing, and I went to seat a primer it wouldn't go. Looked at primer pocket, wondering if distortion had occurred - as these cases take huge pressure.
Nope wasn't that ...... but did rethink and realize - the ''duh'' moment - yep - small primers will do just fine!!!
I amaze myself sometimes - must be age I guess! LOL!
Off to bed now - reloading can resume tomorrow
