I use to, long time back, used a 20 gauge , the two others used a 12 and 16.
I remember that it takes about two weeks before we could go back to the same place and shoot, they have a memory about that long from what I remember.
this was in the 70's when they had no restrictions on crows and you could hunt them anytime in MO. Squirrel hunt in the morning, crow hunt after that and hunt coyote and fox in the evening. Good old days,
