I recovered a Lyman M die plug w/stem that has a 32-20 case stuck on it and the rim about half gone.
Looking at the case, it appears the plug is over half-way down the case. The plug number is not on the knurled stem, so it must be on the tip of the sizing plug inside the case. I will make a guess that it is a longer "R" plug since it looks to be into the case@ 1/2".
How could I proceed? My first guess is putting it into an M die body, drilling the primer pocket out and proceeding as with a stuck case...
