I recommend a PAST Recoil Shield
PAST Recoil Shield
or folding up a towel inside your shirt to cushion the recoil from the bench...either one will help muchly...
The forend needs some special attention as well. A backpack filled with towels or newspaper, or a rolled-up towel...or something else that can be improvised that is soft will replicate the point-of-impact from holding the rifle.
I don't know your level of shooting experience, but recoil management is very important to a novice shooter. You might consider starting off with a reduced recoil load to gain some familiarity with your rifle so as not to develop a bad habit like a flinching reflex, which can be hard to overcome.
