hello guys,vhit.n350/ n3n37 were my powder of choice for this cal/ open gun-non hybrid bbl. ( sti ). unfortunately I ran out of powder, cant find anybody selling. I am thinking of switching to either or both to Hogdon- HS-6 OR HS-7,IMR - HI SKOR-800, IMR 4765, IMR 7625. I need your feedback and experience with these powders from avaliability,cost and ease in reloading (metering)using 550B powder measure. I lived in the toronto area, so my source should be within the area. thanks
