There appears to be a conflict of info between what Dean and JohnK are getting from Speer.
Dean has stated that his contact mentioned that .45 GAP pressures of Speer ammo is 19,900 to 21,000(from memory, sorry). JohnK's contact says no, it's up to 23,000 psi. John's contact also stated that Speer does not produce 230 grain loads because they could not accurately measure the actual pressure of 230 grain GAP ammo.
