Definitely something special about using your Dad's rifle. My Dad passed away in 98 and I had been given his Remington Model 742 30-06 . I had it in the safe and not even hunted with or even shot until I decided I wanted to take at least one racked buck with it if I could. Took it out in 09 and passed on a nice little 8pt while trying to decide to shoot or not, and kinda regretted it at the time. FF to 2010 and hunting with the same rifle, in the same stand, saw the same buck, which had grown some, and after a long wait following him thru the trees up the ridge, I got the shot. Took that buck on my property(that my Dad was raised on), with his rifle, on Thanksgiving Day. And, after my Grandmother had passed away in May earlier in the year, as she still lived there on the property. It's the most treasured mount I have, even tho it's no monster. The memories of that hunt are still as vivid and sharp as the day it all happened.
Good luck making your own memories with your Dad's rifle!
