I measured the OAL of the Excaliber 9mm minor PF ammunition at 1.130 inches.
You sir, think like a reloader. You should definitely consider it.
If the cartridge didn't
'plunk and spin', then a reloader could reduce the OAL to 1.120" or even 1.100" until it did. The problem with factory loads is that it's pure digital 1 or 0, Go or No-Go. But with reloads you control everything... the OAL, the PF, the primer sensitivity, the muzzle flash, everything.
You've been previously commenting on PF. Reloading would give you the option of stepping down from PF136 in increments of 1 until you were delighted with the performance.
May I suggest that you start to pick up all your spent brass.
