Chokes and Chambers

If you measure a Winchester or Remington shot shell you will find that they are 2 5/8 extended

Parker recommended three loads for your gun
1. 1 oz and 2 3/4 dre This was said to be a nice bird load
2. 1 1/8 oz. and 3 dre. This was the standard 12 ga patterning load for all except the heaviest 12 s. Your gun would have been patterned with this load. It still remains today as the standard trap load.
3. 1 1/8 and 3 1/4 dre.

See patterning hang tags and Parker's The Small Bore Shot Gun as source

All of these loads are suitable for your Parker as made and are commercially available today from many sources . Some people have their own favorite loads but the most informed place to start is with the Parker documents

Bruce that is not correct. Just checked a Winchester AA and Remington Nitro 27 Handicap and the case length is exactly 2 and 3/4 inches for each.
