The 70 grn Speer do stabilise. That is what they were designed for - slow twist barrels. In fact they will stabilise in a 1/14. They will work fine. Note: Just looked back and JD has said this.
Any of those bullets will work. Careful atlas joint shot/neck shot.
With the 70 speer especially I would be ok with a crease/lung shot too. I would keep away from the main shoulder mass.
You will know this, but if you shoot a stag in the lungs don't chase him. Just let him wonder off and die. It will happen quite quickly and humanly and he won't go far. Chase him and his adrenaline can take him a long way.
