Two options, if I was you. Of course, I am not.
Leave as is and use on “lay up easy” hunts. By that I mean hunts where harvest rates are high due to target rich environment on calm animals where can get within 200 yards or so. You would be hunting as your grandfather did.
The only other option I would consider is a $1000 - $1500 scope to make this my “go to” rifle on most hunts. Good glass extends your hunt window into more minutes at first and last light which are sometimes the only great part of the day to see animals. I think the total weight of the gun, scope and ammo make this heavier than most set-ups so, if I am correct, this would not be my main gun as my hunts out West often required pack-ins and elevation so a lighter set up was appreciated by my shoulder and back.
