For my son when he was little, I loaded up 80 gr Barnes in a 25-06. It worked good for him. I also have a 7mm 08 and it's a dandy round. 243 is tried & true hard to beat as well. I've put together two 22 creedmoor rifles to shoot 88-95gr bullets. It's amazing how much harder it rings my 500 yard gong vs my 25-06 with 80 gr bullets. And the 25-06 starts out with a muzzle velocity of 150fps faster and more recoil than the 22 creedmoor. I haven't got to shoot any game with it but I can't help but to believe it's going to be dandy for coyotes & whitetail with the same bullet to take both animals. If Savage, Ruger or any of the bigger manufactures want to sell a heap of rifles they should go ahead and start chambering some up in 22 creedmoor.
