e=mc2, Velocity is squared so it has more impact than mass but depending on the loads you can get them pretty close.
I used to shoot my 357mag with a 125gr HP. I used WW296 close to max which generated over 1900ft/sec velocity. After 2-3 firings the primer pockets would be loose and I would rotate the brass down to my LSWC's.
Recoil is highly subjective. So yes it can have the same feel.

"Recoil is a momentum (NOT energy) balance. Mass times velocity of the bullet equals mass times velocity of the gun.
It takes a little figuring to get it in scientifically consistent units, but the IPSC Power Factor will give you a rough idea.
PF = bullet weight in grains times muzzle velocity in feet per second, divide by 1000 to get a manageable three digit number to compare".
125gr x 1170 / 1000 = 147.42
158gr x 940 / 1000 = 148.52
E=mcc (recoil is a momentum, not energy?)
125 x 1170sq'd / 1,000,000 = 171
158 x 940sq'd / 1,000,000 = 139
hmmm?
