There was some discussion recently about bumping up bullet size and it got me thinking about how to do it. I got the Lee 460-350 GB about a week or so ago and it is casting bullet too small for my TCR 87 also the gas checks don't fit. I also have a Lyman 457193 that is also too small for my rifle and I needed a solution.
I have had this device hanging around for a few years.
After some though I figured I could make a swaging die that would do what I needed so I made this die that is just a straight hole about 1.5 deep that after grinding and polishing came out to .4615", and then a 5/16 hole through.
Then the nose punch
that goes into the die thusly.
and the base punch
The die simply drops into the hole in the press and can be adjust by use of the lock ring.
