Gents, Thanks for the great help. I really enjoy the gun and have been shooting 2 3/4 shells through it. I'm thankful to have realized it may have 2 1/2 chambers and asked. I'll measure just to verify and then stop shooting it until I get back to the states and get correct ammo.

Lagopus, I'll put the info on the action and lock up in my other thread on this gun "Trying to date a Midland SxS"

Thanks again to all.

Sincerely,
Patrick
