Current SAAMI pressures are as follows:
.38 Special = 17,000 PSI
.38 Special +P = 18,500 PSI
.38 Special +P+ = no recognized SAAMI limits
.357 Magnum = 35,000 PSI
A lot of shooters for some reason think the +P on a .38 Special makes it a higher pressure round than a .357 Magnum, that's no the case. Even a higher pressure .38 Special +P+ with a probable pressure of 20,000 PSI won't stress a .357 Magnum revolver in the least, especially a M627. Have a good time at the range with those Federal rounds...
