6mm rem mag or 44 mag?

Will be taking my son on his first Hog hunt in TX this winter and was wondering what would be a better choice? First if your wondering why I picked those 2, its because they are the smallest cartridges that I feel will do the job that I have access to. My son's 8 and my 243 is way to long and heavy. Shots will be 100 yards or less. I have killed them with the 223 but want something bigger for him. Can I down load a 45-70 enough to kill at 100 and recoil be ok? The 44 is a rifle.

I would go with the rifle he physically handles the best. A .44 magnum rifle would probably be my choice, as I've had good luck with kids using it.
