My buddy shot at a 6pt last year at 10yds. The deer was standing still He was using an 835, too. He pulled the trigger, and the buck just looked at him. He looked through the scope to shoot again...and couldn't see the deer very well.

It seems the end of the barrel had "banana-ed"....(peeled like a banana) and was split 3 ways.

Obstruction most likely wasn't the problem in his case...as he was in a stand and didn't walk far to get there.
