Looking for advice on how the reduce the rim size on the .414 Super Mag cartridge by 0.037" to get to the correct diameter for the .401 WSL. I'm looking to load about 200 rounds and I don't anticipate doing this more than once, so I'm not looking to invest a ton into a setup to do this. I was thinking that I could use a drill press and emery cloth but getting a setup that will give consistent results may be iffy.
Suggestions?
Thanks.
