Just read all the comments and found them interesting.
As I age, I find more and more that massive power isn't needed to kill deer quickly. Bullet performance is the key. And, recoil becomes more painful at 72 than it was when I was 50 and younger. In fact I didn't really become sensitive to recoil until about 65.
So if you are REALLY recoil sensitive, work up a load that kills only out front. If recoil is only bothering you at a shooting bench while sighting in. A 25 pound bag of shot between shoulder and butt is unbeatable. I don't know of any gun that can hurt a well man with a bag of shot in the way. The coarser shot the better. Like #2 or BB. What happens inside the bag is amazing, as the shot are spread sideways when recoil hits, redistributing the direction of recoil out into the shot rather than back, plus of coarse the mass of 25 # of lead in the form of a very comfortable pillow. It is unbelieavably gentle on the shoulder.
If you sight a rifle in with a bag of shot you should try a shot or two off hand like you'll be shooting in the field, with a strong grip, to be sure POI is still right. The worst way to take recoil is shooting prone with the buttplate dlamming into the top of your shoulder and the whole body weight solidly behind to prevent the shoulder from flexing away. Second worst is from a bench.
Being large is a serious fault as well, because of the shoulder getting crushed trying to move a large body mass. Those who can stand the most recoil with the least pain are those with hard muscle and slight build, who grip the gun tightly. Their ligher body weight moves away with less pressure on the shoulder then with a heavy person, and hard muscle will withstand much more impact without pain than soft muscle and fat.
I have personally found that the best way to keep packing weight down for hunting is to eat light for a few days prior to a a hunting trip. It isn't hard to peel off one pound a day, for me anyhow, so a couple weeks of that and I'm traveling quite light. A heavy gun is easier to tolerate then, especially if I do some hiking while carrying the gun to harden up some.
