RE: nef single shot 12 gauge turkey?
For a number of years I shot turkeys with NE's Pardner 12. Although it only used the 3 inch shell it would almost knock you into tomorrow. I filled the stock with lead and put an aftermarket pad on it which helped some, but there was no mistaking when you touched it off.
I must say though when I shot it in a hunting situation I didn't notice it all that much.
