I'm wondering if it might be rechambered into .303 British. I'm looking for a box of .303 rounds I have around somewhere, and will try it later.

Fire-forming cases will have to wait a bit. Years ago, I said: I'll never be bothered to reload again, and gave all my stuff away.

I bought a few Lyman 310 tools recently in response to the ammo shortage, but I will need to pick up a few more tools and lots of supplies.
