How accurate is that 9mm Ruger. That looks like a very fun rifle.
He is gonna burn thru your lead and powder supply and all you will have left is a smile on your face.
Trevor will never have too much fun shooting Grandpa's guns.
Bet he has his eyes on more than a few of Grandpa's beautifully stocked rifles, too, and is antsy to give them a try.
Good group for quick shooting like that.
