"Cor-Bon .45 Colt+P 300gr is at 1300fps" . . . listed as "Not to SAAMI specs"
"Buffalo Bore has some 340 gr .44 mag that clocked over 1400 fps" . . . listed as +P+ for which there is no SAAMI spec.
"Underwood has some 340 gr .44 Mag they rate at 1425 fps" . . . listed as +P+ for which there is no SAAMI spec.
All variety of high-performance ammo is available, and with none of it do you know what kind of pressure you are subjecting your gun to. I do not condemn any of this ammo out of hand, but one should be aware of the facts.
Maximum SAAMI spec for .45 Colt is 14,000 PSI . . . maximum for .44 Special is 15,500 PSI. This would perhaps give the handloader an advantage when reloading the .44 Special, if he has a way to determine the pressure his loads develop.
Maximum .44 Mag pressure is 36,000 PSI so I guess one might load .44 Special cases up to that pressure level for use in a Magnum gun if the cases themselves would take it . . . just be sure you keep them separate from your "real" .44 Special ammo.
All JMHO.
