I've got version 3.6 and get slightly different numbers than you.

14.6gr AA9 gives me between 69 and 75k psi, depending on which listed Speer GD I pick, between 119 and 122% compression.

14.6gr Enforcer gives me between 58k and 63k, at between 125 and 128% compression.

Even if you're pressure theory were correct, I can't see fitting that much powder in the case, under ordinary rules.
