I don't know why I even checked out this post, but I say keep the rifle. A pre 64 Winchester will continue to increase in value. The bow goes for about $1300 in the local shop near me. Next year same time they will still have 2 or 3 that they will offer for around $1000. The next year it will be down to $800 to $900 and still essentially brand new.
Investment wise keep the rifle!!!!
Now if you have your heart set on the bow, then I guess get the bow.
I shoot traditional, and traditional bows hold their value and will continue to hold their value. Besides, they're more pleasing to the eye.
