Thanks for the reply.
I'm not super worried about it since it drops all the way in and out without a problem. I'm just used to sending handloads back through the seat/crimp die if they won't spin, and then putting them in the reject pile if they still won't spin after that, so I was curious to hear your experience. Given that it would seem that your P99cs behave basically the same way with 147 HST and runs it fine in them, I'll at least run a few mags through the 'c' and the full size and expect it to be fine. Trust but verify and all that.
