Yep, I got lucky! Thank you to the guys who gave me pointers, I really appreciate your help.
I went out again this evening to a place I tried last week during the day but had no luck. I knew they were around because of the tracks I saw and the fact they got into a dead calf here. I got there about 10-20 minutes before dark and set up about halfway between where I'd hoped they would come out and their lunch room (calving barn). I started calling and continued for two more sessions 25 minutes had passed then they appeared about 70 yards away . I couldn't believe it I felt like I was seeing ghosts! My gun was pointed the right way and near my shoulder. I shot and hit the first of the two. I was so excited when I cycled my bolt (the other was still standing there) that I pulled it back just far enough to eject but not load the next round and I heard "click" and knew right away what I did. Too late then. I called in and shot my first coyote! It was one of the most exciting hunting experiences I've ever had. I could see for hundreds of yards all around me except for right where they showed up.
I did try to weight it with me on the bathroom scale(in the garage don't tell my wife I took it out there
),then just me without the coyote and subtracted the difference. It was about 40# and I can't speak to the accuracy of my system either. I have no Idea how big the get around here. It is a male.
I know this is nuthin for some of you guys but I am pumped!!
