I would say it depends on how you hunt, and how your self-discipline is. In my area, most of my shots at hogs are inside of 50 yards, and often inside 20. Also, about 1 out of every 3-4 hogs I see will stand there looking at me facing me like it is trying to decide if I am a threat, or if to charge me, or just what I am, or whatever is going through their heads. Those I have taken plenty of with a .32 ML or a .22LR pistol while hunting rabbits and squirrel. Now the rest are less than perfect shots, with the hog either being at any random angle you could imagine or running. So here is what I do. If going after small game, I carry a .32 ML (or .22LR ), and if I stumble upon a hog that presents a perfect shot opportunity of either a broadside shot or a (non-angled) shot at the fore head, I take the hog. But if I am going out with the intent to try and find a hog, I carry a .50-.54 ML, as it allows shots at various angles that I would have to pass up on if carrying a small gun. So are you willing to wait for the perfect shot and let the hog walk away if you don't get a perfect opportunity? If so, I would take your .36 or .40 out with me, but if not, definitely go with the .62 and KNOW you have enough gun.
