I have a sizing question concerning my 1898 Krag sporter. I'm shooting #311284 ACWW sized to .311"dia. and have always left the .308"dia sizer in place since jacketed sessions long ago. Since I'm sizing for .311" dia. #311284 should I size my cases with the .308"dia.sizer or swap it out for the .311" sizer from my 7.62x54R set ? Thanks
