Hello all, I am having a 338RUM built and my smith wants a dummy round to cut the chamber. Problem is I have never had a 338 RUM or loaded for it so I have no idea what OAL I will need. My plan is to use the 250 grain Sierra match king for target but will use other 250s for hunting also.
Any ideas on what OAL I need to set up this dummy round so I can get the best use of bullet to rifling adjustment?
Thanks, Nathan
