I have been thinking about using zinc to melt into the bottom of a 30-06 case and then drill the flash hole through the zinc. Im looking for 32 pistol type performance with very reduced capacity.
I know that the cartridge will no longer expand to the chamber but the neck should still expand to seal. The idea is to use pistol powder in the 06 to send a 130-150gr bullet in the 700fps range
Not sure how the zinc would hold up to the powder charge. It may need a oversized flash hole drilled and a brass insert pressed in to protect the mouth of the flash hole. I have a lathe and mill.
any thoughts
