There is no such thing in my opinion as "too much" for a deer. Granted now we are not talking center fire cartridges as some of them are insanely powerful. I've shot a doe with a 460 grain .504 conical and 90 grains of T-7. The deer dropped in its tracks and there was not as much damage as I thought. But I did not shoot center shoulder either. And I never remembered any recoil when I shot. On the range there is some recoil but nothing I would shy from.

If you are recoil sensitive (as I am) you would think this would be a rugged load to handle. But its not as bad as you would think. A lot depends on the weight of the rifle/barrel and the shape of the stock.

Although to be honest after I learned how well 65 grains of T-7 and that same conical shoots and the penetration, I have sense lowered my standard hunting load FOR DEER.
