Guys my gunsmith is about to chamber my new fluted Krieger barrel in 300 RUM. I want to shoot the 180 grain Accubonds in it with the boattail/bearing surface junction seated to the neck/shoulder junction. He uses a throating reamer to get the throat right where we need it. The problem is that we are unsure if the 300 RUM should be seated in the lands, just touching, several thousandths off or way off the lands. Can someone with some experience with this cartridge give us a good rule of thumb?
