Anyone have a 338 rum bdl in a wyatts mbe-3 mag box? Looking to run the 300 class bullet and haven't seen any throated a little longer. Would anyone happen to know the boat tail junction to the shoulder to optimize the seating depth? Not looking to do a 300 edge because I would like it to be a reliable repeater. Any info is appreciated
 
This just got finished up a week ago. 338 rum, terminus helios action, Wyatt's cfe9 4" mag box. Had to mill the rear mortice and bolt stop a bit to make it work. 300 bergers are 3.9" to lands, 270 eldx is 3.835". I'm going to try RL33 so I'll more than likely be running within 5-10 thou from lands for initial load work up.
