The Rem 700 is a good place to start with the factory SPS in a upgraded stock you can easily reach out to those distances. Then when you shoot out the barrel and decide you want to continue you can build a custom gun out of the action.

I am currently having one built on an old 700 action I had laying around. With any luck it should be done this weekend or next week. Not including the cost of the gun and the McM A5 stock I already had it cost me about $500.00 in parts to build it up. Havent got the bill from the smith yet so I will report back on that.
