Talking 100yds completely free hand? Like no kind or rest? Not even a stand rail, tree, your knee or anything??
That's not crazy bit again standing there shooting a deer freehand at 100yds isnt easy either. I always find something. At the very least my knee and elbows. Been a few I had to hold the gun and shoot but it's rare and I grew up gun hunting off the ground.
Slow down...focus...find something to atleast rest on.
Also, don't know if your shooting a field or open area or what...brush and "invisible twigs" are a killer..only deer I've missed with a scoped rifle I know that was why.
One year a buck came out of a small drive and was standing on the next hill. Buddy shot and it ran and stood infront of me. 4 shots and he's still standing and dancing around. I couldn't understand it. I had 1 round left. I cranked up the scope and realized the sun glare washed out all the branches between me and him. I could see them cranked up...found a hole and dumped him.[ Post made via Android ]
