I use a boss buck that has been beaten to crap, have the legs screwed on with drywall screws. Works great if the bucks are looking for a fight. Make sure to handle it with gloves and spray it down completely once in place. I only use 1 antler on it, seems to instigate more bucks than with both...
MAD turkey whistle (if you have to ask you’re too young)
Suckered a lot of people with that gimmick! Yes, I was one of them, worked great at annoying the dogs.
I like Patternmaster chokes for waterfowl, but Carlsons makes good chokes at reasonable prices. Your factory modified choke will work fine also, pattern it and see what you think.
