The bore on my Arisaka meaasures .31105 and the Lee sizing die is .311. I need .312. Would you suggest I size to .311 and PC to .312, PC to .312 to .313, or use valve grinding compound to enlarge the sizing die to .312? I was thinking of using the same ram rod and put valve grinding compound on it or a bullet and drive it through the sizing die a few times.
