Several early 11-ga Parkers were chambered for 11 paper or 11-A brass shells
0.825" head to 0.810" mouth. A machinist tried to make sleeves for my ser. No. 3561 but failed. The sleeves were so thin they become out of round and hang up on the brass of a modern 12-ga shell,

I am thinking of trying to fireform AA shells by just shooting them in the gun. The ones that do not split at the base should then be the perfect size for these 11-A chambers.

How do I set my MEC GRabber so that the Collett wIll not then re-size them to the 12-ga head diameter 0.810"? Maybe I can adjust the colett--or shoul I remove the primer manually and just skip station 1 and go directly to station 2?

Any suggestions would be greatly appreciated.
