I upgraded from a 5.5oz buffer (not sure of actual brand but it came from PSA with the kit I ordered), to a 8oz KAK industries extended buffer. Bolt can still lock back but this prevents over-travel. As for the firing pin shroud, I don't know. When I pull the case wall out of the chamber tomorrow I'll post a pic.
After going over a few reloading references (Hornady Vol 1 and 7, Speer Vol 13) I'm still within safe pressure for 115gr bullets with 6.1-6.2 grs of unique powder (6.3 listed as max). I'm thinking I should back off the powder for my next reloads. I'm using a mixed batch of range pickups, but I haven't seen any indications that these were previously reloaded cases. The first issue blew out the primer, this one didn't. The intact primer wasn't bulged or flattened at the base of the case, so it sort of contradicts the too much pressure idea I have.
