I am loading for a 300 RUM on my Lee classic cast press, with a set of redding dies, and loading 210 Berger VLD hunting bullets. I am having issues with consistent OAL, I'm getting differences of up to .005" per load, and am not certain why. Any thoughts on something I might be doing wrong, or is this just par for the course? I certainly hope it isn't, that is just too much of a difference. Thanks in advance. Also, using never-fired OEM brass all checked and are consitent OAL, FYI.
