Yes - 3/8's Inch is easy for bullets as long as there is 3/8" brass or copper tubing and I own a pipe cutter. But- then, a 9.3 would also work as I have a die that reduces .375's to .367" in one pass, as easy as sizing a .300 WinMag case- just lucky, however Lee will make you a 3 die set to do the same thing.
