Depends somewhat on your hunting style and the condition of your .06. Will the pre-64 cause you to protect the rifle instead of concentrate on the hunt? A week of hunting is often good for adding character (ding or scratch) to whatever I'm carrying. I love everything about how my pre-64 .06 handles and shoots but it is about 99% condition and I have other, call them 'utility', rifles that perform well so my pre-64 doesn't go along for the rough hunts.
