Yes
I started with 200 rounds of factory loaded ammo, 15 of those are still unfired.
Once I had fired 100 of those rounds I sized the brass then trimmed and turned the necks.
Of those 100 cases I primed 14.
Of those 14 I loaded and fired 13. One is still primed.
I lost one of the twice fired cases somewhere.
It was at this point that my PRC barrel showed up and I never looked back at the Creedmoor.
