When I made my misguided attempt at using the 300RUM cartridge, I bought some Federal Magnum primers. The 300RUM rifle went down the road and I have a couple flats of Mag Primers left. I am loading for 280Remington. Should using the Mag primers make much if any difference in where my bullets print on paper?
