I had the same problem bill with a little Breda 28 gauge. It weighed less than 5 lb and kick so bad that after firing the first trigger I did not want to shoot the back trigger. Beautiful little gun case colored sidelock. I sold it at Ernie's several years ago.

I have a A&F rizzini extra lusso in 28 gauge that weighs 5 lbs and only shoot 28 gauge federal premiums at grouse and woodcock and the recoil is not that bad and also shoot pheasants with it with #6 shot and does the job with no problems.

That gun gets pheasants too
