Can this be accurate? 300 Ultra OAL
Been trying out my new OAL gauge on my 300 RUM and it measures 3.795 bullet to the lands with a Swift Scirocco? .195 over the stated (published) OAL of 3.600 Most of my other rifles do not have this much difference. Does this make sense?
I was going to start by backing off .020 which would leave me at 3.775 OAL Should I begin to seat my bullets?

Good Question. Just got done measuring it and seating bullets when I saw your reply. The magazine max is 3.680. So I'll be .115 off the lands. Don't think pressures should spike to much? I backed off on the loads a bit using IMR 7828. Thanks for the help
