On an honest note: If a/the rifle won't hack that kind of treatment it ought not ever be used for LRH. Just my IMHO.
I unexpectedly tripped in a low spot where there shouldn't have been one and went down like a ton of bricks. Broke a leg off of the bipod (which BTW was redesigned to handle that kind of stuff). The bipod was also torn from the fore end (that's been remedied also). This happened early in the season and I never even tho't of or considered checking zero.
However, after no shot presented itself at an animal, after the season I went to the range and things were spot on. Pretty much luck this time. But I'm working on remedies/prevention.
