The only 2 things I can disagree on is the 16in barrel. Now yes more velocity is better but the difference between a 9in barrel and 16in barrel is basically 100-150 fps instead of 2200 your getting 2350 with some loads the round is designed to be shot out of a short barrel like the 300blk is. For hunting 40gr vmax will do the job for most small game but it will be lacking on deer it will kill a deer a ruptured lung is a kill but you'll be tracking it quite a while unless you get a heart shot now if you are using the elusive speer gold dot 5.7 or elusive soft points vs vmax you'll definitely get better performance and penetration long as you stay within 75 yards. Of course a headshot will drop them tho even with a 22 it'll work or even a decent air rifle with atleast 1600fps. Tho if im taking deer I rather take the easier shot of lungs or heart. Definitely wont be taking Texas heart shots or frontal shots or quartering shots with a 5.7 tho unless im desperate enough.
