Just my 2 cents worth. I would not go with the 270 wsm because of ammo or case availability. It is hard to get now and probably will be worse in the future because it is one of those good rounds that just did not catch on. I would also not go with a semi auto for two reasons. First is safety with youngsters when they get excited and forget that a live round has been put in the chamber after they shot that animal and forget about safety. Second is accuracy, they are nowhere as accurate as a good bolt gun at longer ranges. If your son is shooting your 6.5 Swede OK then why not get him something like a 6.5 creedmore or 260 Remington in a good accurate bolt gun. Get a 8 twist barrel and you can shoot any bullet 100 to 160 gr with no problem. These rounds with the proper bullet will take anything the 270 wsm would. If push came to shove and factory ammo became hard to get you can always make you own cases out of the every present 308 Win. Which come to think about it would not be a bad choice also. I have killed a bunch of whitetail deer with the 308 with 125 gr Nosler ballisitic tips running 3000 fps at the muzzle. It has much less recoil than full house 150 gr loads. You can even load it down lighter. Hodgdon has youth loads using H4895. I shoot 46 grs IMR 4895 which is a max load in my rifle. Like I said, just my 2 cents worth. Good luck in your quest.
