Hi with a 77gr 3000 FPS +- to answer your first question
2nd question
I did not take the shot since I was spotting, but with that same rifle at about 400YDS +- "I had ranged that area several times" the coyote was walking across the field and was sideways to us, I told him to put the cross hairs horizontal with the spine "there is little drop at 400YDS if any and he took the shot and hit him. I saw something in the spotting scope but did not understand what I saw until I got to where he was lying. What I saw was surreal the head and shoulder blades along with the front legs were intact, as well as the rear legs and hips and tail. What was missing was the whole misection I mean Missing no guts, organs, ribcage, Nothing it took awhile for me to realize what I was looking at neither of us said a word for a while not until we got back to our setup. That was a 4500FPS load not my fastest but a good stout load, you can't load everthing max load everytime that is unrealistic.
