Hi I am new to the site. My uncle just gave me a Model 99. I know the the caliber is .250-3000. Other than that I know very little about the gun. I would like to use the gun but need to know what round I can use and where I can find it. The gun came from a cousin of his that passed away and he wanted it to stay in the family. So he wanted me to have it. It seems like a great gun but the history is a mystery to me. When was it made? What should I check before I use it? Would I be better off not using it? The model # starts with 362xxx. Also is it something I should get insured. I can post pics if that helps. Thank you.
