Gas Checks

[Sliver Shooter]

Hey Guys,
I have a question about gas checks. I am going to cast for my 7.7 Jap and .303 British and wondered what or where does one find gas checks for a .311 or .312 bullet?

............You don't. You use 30 cals for'em. If you anneal them you can use 8mm's.

Buy a gas check maker from Pat Marlin and you will never be without again.

I'm sure you could just use 30 cal gaschecks. I'm sizing Lyman 31141's to .312" for my .30-30 and using 30 cal gaschecks.
