like the 460 10 lbs rifle from the factory has 92 ft lbs of recoil with a 500 grain @ 2500 fps .Now add 5 lbs to the gun which a 15 lb gun with the same load has 61 ft lbs or recoil but only 16 recoiling fps .I think the detached retina's have more to do with the individual than the rifle,recoil, or caliber itself
The detached retina issue is a combination of excessive firings and weak retinas.
I would venture to say that few people can shoot a rifle with 90 ft/lbs of recoil and 30+
ft/sec recoil velocity very many times in a row off sand bags.
This is a place for a lead sled or as we used to do, (Place a 25 pound bag of lead shot
between the recoil pad and your shoulder to increase the overall weight of the rifle, thus
redeucing the recoil velocity for extended sessions at the range.
I shoot a lot of big bore rifles (Most have no muzzle breaks) and I still limit my self to as few
shots as nessary to break them in or get a good zero.
There are other issues that can effect felt recoil such as the stock fit and the design.
There was another issue brought up about the weapon recoiling only after the bullet leaves
the barrel. And it depends on the type,design and weight of the firearm. Example= A pistol
will recoil before the bullet exits because ,It is light weight, the grip is below the center line
of the barrel that allows the weapon to rotate upwards(The reason the front sight is higher
than the back)
On a heavy weapon recoil velocity and any movement is slowed by the mass and the bullet may exit the barrel before any movement takes place.
Thats the best I can explain it. Maybe some one else can explain it better than I can.
