I don't believe there is a +P SAAMI designation for the magnums. That won't stop a manufacturer from using the term though. One question would be +P relative to what? If it is relative to the current SAAMI .44 Mag maximum, you may be OK because it may still be under the original .44 magnum pressure designation?
but here a different question will they fit ? .
i know heavy bullets dont fit in s&w guns because the bullet is longer . but will heavy bullets 320-350 grain fit in a desert eagle magazine or chamber ?
.......comes the most powerful loads that can be concocked at my reloading bench.
My DE has withstood the power of the same loads that people use in their Ruger Red Hawks and Super Blackhawks.Not the heavy weight hardcast but the jacketed bullets that are of the 265 and 300gr variety.
My weapon is almost 20 years old and has countless full power loads through it. So my answer to your question is .....YES. -----pruhdlr
