Ortolan and Chux,
Thanks for taking the time to reply and your good advice. However there is a miscommunication regarding the Rio shell I am talking about. The 28 refers to 1 oz. of shot not the gauge and when I wrote it I should have pointed out it is a subsonic 12 gauge 1 ounce shell. I am still hoping it will have very low pressure even though the hull is 2 3/4" and that I might risk using it in 2 1/2" chambered gun. It would therefore be an alternative to $8/box low pressure shells in 1 oz. and alternative to spending too much time in the basement reloading my own.
On another topic. My wife was shooting regular 28 gauge loads in a 5 1/4 lb Franchi AL-48 recoil operated semi-auto with the stock cut down to 12-1/2" and was black and blue from the experience. Part of the problem was it was not a gas operated semi-automatic and the other problem was the size of the butt had been reduced by cutting the length shorter. Two lessons learned and the gun was sold.
