Try to find any markings that give you the length of the cartridge and if it has been proofed for Smokeless Powder or otherwise known as Nitro.

Ask the Shotgun Experts

A good local gunsmith will tell you if its OK for modern powder. Just a suggestion here. And NO guarantees. Find a max load for that gun. (21/2" case) Load up a cartridge same max load + 1 grain powder Take out in field, wrap up in an old blanket (very effective at stopping shrapnel) Stake / tie down Fire using long string and hiding behind BIG tree. LOL Check for damage.
