X2 on the Remington 512 Sportmaster, bolt action with a tube feed. My grandfather gave it to me for Christmas in 1980. I was 10. I have shot more rounds than I can count through it and it is one amazing shooter. I was stationed in Alaska and had my dad ship it up to me in 91. I bragged to my wife about it's accuracy. She had heard that boast from many people about their guns over the years and figured my boast was the same. After shooting it, when the topic comes up she brags on it for me.
