Re: 308 bolt
that is a good start in getting a Precision rifle built in the future. Many a great build starts with the Remington 700 platform. When you burn the barrel out a couple of years from now you can use it as a basis for a tactical build.
All your items that you are looking for are top notch; however, if you are new to this world I would spend my money on ammunition up front and practice all that you can.
At first get a good scope (buy one used on the Hide) put a 20 MOA base on the receiver, and get a take off PSS stock or H&S stock at first and have it bedded. Then go shoot it a lot and get good with it and then get the more expensive items later. Just some thoughts.
