Geez, we have all been there. Main problem is, there is no right answer, and whatever answer you choose you will later be unhappy with!
I have never regreted clearing out a plain Jane rifle from the safe, but I have always felt really bad later if I have gotten rid of a beautiful rifle that is very accurate and functions flawlessly! I mean, finding these types of rifles is not easy, and owning these types of rifles is the whole point of it all!
My advice: If you do not need the money, then tuck the BLR into the back of your safe and leave it there. (Or, if you feel comfortable about it, put it on the wall in your den for the beauty of it.) Use it on those very special occassions when you are hunting in nice weather and better terrain. And when the time comes to part with it, give it to a deserving son, daughter, niece, nephew, etc., who will treasure and care for it because it was yours.
All of us have that beat up plain Jane for hard hunting. So don't feel bad about having two rifles. Also, is the plain Jane in the same caliber? If it is in a heavier caliber, such as .308 Winchester or more, then you really ought to keep both rifles, for different types of game.
