12 ga is a little over kill but if that's all you got, 5 or 6 shot would be the best, modified choke, and I peal the skin off as soon as I drop them and then gut them afterwards..... Take the feet and head off as well... No critters too get into the game pouch of back too the house.... I carry plastic bags with me too put them in, plus I wear surgical glove while cleaning them.... Poision ivey has a way of finding me all the time...... :smiley_clap: I use the .410 for them, but have used 12, 16 and 20 as well... Just like the .410 these days.....
