So, I have never seen nor fired this gun. It is my brother inlaw great grandfathers rifle. He says he has not shot the rifle in more than 20 years, but he says they stopped shooting it because the primers started backing out on the fired brass. They don't reload so I would have to assume that all the rounds fired in the rifle were factory. He called me looking for a gunsmith to possibly fix the rifle as a present to his father this winter.
Now to be honest my brother in law is horrible about not cleaning his firearms, his 257 roberts was so tight I had to use a 6mm jag just to get a cleaning patch down it when i started.
