Sorry--didn't know which forum to put this one in.
I have brass in 338 Win Mag. I have a firearm in 300 Win Mag. To transform the 338s into 300s, do I anneal, neck down and fireform? Should I neck down in steps? Should the brass be trimmed prior to fireforming?
Also--I have Hodgdon Clays available. Is 5 grains with a bit of toilet paper enough for fireforming, or should I FILL with cream of wheat, pack down and seal with wax? More/less powder?
Thanks,
