If this is way off course then I am sure someone will be quick to say so. It seems to me that 28.5 great of cfe is a very mild charge (most all here are running over 30).
I purchased an upper from a member here that was running g a type 2 bolt in a type 1 chamber. The result was case head seperate on from excessive head space. You mentioned you were shooting a type 1 bolt, are you 100% sure this is correct? If you had a type one bolt in a barrel that required a type 2 I am thinking "if" the bolt would close it could be jamming the bullets into the lands and giving a higher chamber pressure.
Again, I'm no gunsmith just been head scratching a bit. Hope you get the kinks worked out, I know they can be frustrating but this is an awsome round in the ar15 platform.
