I shot a big'un 28 years ago (325 lbs), cleaned it immediately and well and had it on ice within 4 hrs. I sent it frozen to the butcher who made ,among other things, bone-in pork roasts that my wife cooked like a beef roast, with cream of mushroom and dry onion soup mix. Tenderest and best tasting meat we've ever had. Gonna retire in 2 years and spend lots of time hunting hogs.
