Butchering game too soon after the kill?
I read somewhere that one should wait for about 36 hours before butchering any game animal. The reason was that this was about how long rigor mortis lasted. During the first 36 hours after death, while rigor in in full swing, the meat will likely be tough.
Thinking back, I can say that the toughest game meat I have ever eaten was from the bull elk in my avatar. We butchered it less than 36 hours after I killed it. Even the back strap and loin were tough, though the meat had a good flavor.
I can't really say how soon after death other animals I've killed were butchered, but I'll bet very few were cut up less than 36 hours after taking them. And, I know a lot of people like to hang their animals and let them age.
Gun control laws make about as much sense as taking ex-lax to cure a cough.
