I loaded 38gr of the Russian powder into PRVI .303 brass that I'd previously used in one of my Krags.  Used Federal 210 primers.  Since the Russians left me a nice crimp groove, I decided to put a slight rollcrimp in them.  OAL is 3.065".  If I loaded the bullets in Krag brass and seated them to max magazine length, I'd only get .035" closer to the throat.  Hopefully the improved ignition and more consistent powder charge will help.  I've used the bullets from the light and heavy batches, keeping the 173 point somethings for later.  They were in the majority.
