I thought of the question of using NATO-spec (cross-in-circle headstamp) 9mm ammo in the Rohrbaugh.
It's not "+P", but then, NATO and other European ammo isn't SAAMI-rated.
I've shot quite a bit of this in other 9mm guns, mostly 124gr, and not found it to be particulary "hot", and wondered if anyone else had thought of this or used it, and with what results?
I'm reluctant to use it in the Rohrbaugh since NATO spec bullets of 124gr usually go 1250fps or so from a 4.0" barrel, which certainly approximates the results with "+P" rounds made in the USA, but I don't know the CUP measures for NATO-spec vs. "+P" rounds, and maybe NATO-spec stuff is OK for practice?
Any ideas?
