You can shoot heavy recoil rifles from the bench if you block up the rests high enough that you have to sit upright and don't "lean into" the rifle. This allows the recoil to rotate the body around the hips rather than "compress" the upper body. Some of us are decrepit enough that we can't stand without the help of a cane and shooting any rifle "one handed" is pretty rough". Even this way, you will want to limit the number of shots in one session.
