Re: looking to built first bolt rifle
The problem with asking this question on a board like this is that you are going to get answers all over the place and most won't have completely read your initial post.
You stated that you didn't want a pocket killer.
Some of the answers you have gotten are for a custom rifle costing over 3500 dollars, that is without the glass.
Are they worth it? Hell, yes.
Can you afford that, or are you patient enough to wait and purchase all of the parts?
A bighorn action is going to run in the neighborhood of 1100 bucks. Once again, it is worth it, but is it worth it to you?
If you decide to go full on custom right from the start, good on ya. You can't go wrong that way, you will have a rifle to be proud of, it will be far superior to anything you can buy off the shelf with the exception of the TRG and AI rifles.
If, on the other hand, you want to shoot a very accurate rifle now and slowly have work done to make it an absolute laser, I recommend you start with something like a 700 Varmint in .308.
Why .308? Because factory match ammo is the same price per round with the .308 vs the .223.
You only save money when you reload as the powder consumption is far lower and shipping the bullets is far cheaper on the.223.
The .308 is also far more versatile.
Install that varmint rifle in the stock of your choice, it appears you would like the Mcmillan A2 or Manners MCS T4, excellent choices indeed, have them bedded for best results or get the mini-chassis in the manners.
Add decent mounting hardware like this:

And a good scope like the Weaver 3-15 Tactical or 4-16 viper PST and you will have a very solid gun that will most likely shoot around .75 moa.
You now have a good, solid foundation to build from.
When funds permit, install a new trigger. The Shilen or Timney are going to be excellent choices for a field gun.
Save your money.
When funds are available again, send your barreled action to one of the smiths here on the hide and have the action and bolt face and lugs trued and a match grade barrel installed.
If you wish, have a side bolt release installed. It doesn't make it shoot any better, but I like mine.
