The 38 Special looks promising as does the 38 Long Colt. The real issue may become the base.

The other alternative is to have a chamber insert made up.

Ace made an insert for my drilling 9.3x82r so I could fire 22 hornet in it. SAAMI spec for the 22 hornet is 25,000 CUP. You have to call him on a Sunday morning to speak directly with him.
