I am a n00b when it comes to bolt action rifles and am looking to build a nice tactical .284 Winchester to go with my single fed f-open rig. I am looking for an action that I can mag feed the 162-amax's - 180gr Bergers with. And would like to keep the total cost of the rifle minus glass/bipod to 1800$. I don't mind buying used but I am just not sure what to look for yet?
