Used them for the first time this year, 2 deer dropped where they stood! Ranges 35-60 yards, have shot deer before at these ranges with a shotgun, but never have I seen them drop before like that. Very impressed, so much so considering them in my 20 ga. I know this topic is a bit old, but just came across it when I got back from my hunt, thought I'd throw my 2 cents out there because I know everyone is always looking for current info on topics like this, myself included. So if anyone has shot the 20 ga in the field wouldn't mind the feed back on how they performed. I'm sold on the 12.
