i decided to try hunting some crows this weekend at my friends camp i hear them in the mornings gathering and in the evening flying to roost...i heard them flying to roost so i ran grabbed my camo jacket and my call(my turkey locator lol) and my 12ga...all i had was 7.5 shot and i had a modified choke....i know the shot is small...anyways they seen me jumo in the weeds(i was 20 secs late and didnt get set up in time) and they seen me and started to flare so i cut loose they were about 45 yds out or so...perfect 20 yd shot if they would have keep coming...im not sure if i got the one i shot at both times the first shot he started a fall and started flying agains then the second shot he went below the tree line after the shot and i figuerd he was trying to be safe...but he could have fell i dont think so though....how should i call with my mouth type call?l..like how often and note types?...is there a sight i can maybe download a track and burn a cd of crows like johnny stewert calls (i think thats the name)and use that in a cd player and shut it off before i shoot? i really dont want to buy much to hunt crows except some better shells..so i thought maybe they hit the net for download...also what shot load and choke is good for crows?? can i manage with my hand call? thanx
