I have one of those in 22 magnum. Would definitely put a hurting on you!! Good shooting lady!!
I used to have a double barrel derringer style “snake-eyes” .45 Colt aka 410 gauge little gun. With 410s in it the shells were almost as long as the barrels and the pattern was pretty wide. I used it for copperheads on some property I have out from town. Then I kept it for home defense loaded with rock salt and BBs. I never met the necessity to use it for defense but It didn’t take a lot of accuracy and it would hurt.
