Appreciate all you knowledgeable roller-delayed guys helping the noobies out.
I got my PTR9k out to the range for its first full range session this weekend, along with my AP5. The PTR has the 80* locking piece in it. I started unsuppressed with some Syntech 150gr stuff and the gun simply would not run it at all. Put the can on and it ran like a champ. I stuck the LP from my AP5 in the PTR and tried it unsuppressed and again it ran like a champ.
So I understand that the 80* LP is to prevent receiver bulge from the higher pressures and bolt speeds that come from running suppressed (and/or shouldered with a stock), but I'm wondering if there is a round that will allow the gun to run suppressed and unsuppressed without having to change the LP out?
Thanks!
