Which action to use for a budget 308 precision rifle build?

[nuke]

I want to put together my first rifle.
What I have:
1. A savage scout (model 10) 20” barrel 308 SA 4 5/16’?(older rifle/first GEN scout, must be 4 1/4"?) Bolt spacing, staggered detachable magazine with side release button. 3 screw adjustable trigger. Pencile barrel.
2. Stevens 200 30-06 LA 5 1/8”? Bolt spacing, blind mag center feed.
What I want is a 20” 308 heavier barreled rifle in a better stock and a decent trigger. I would be using this for ranges out to 1000yds. I have been shooting 3 gun and would like to shoot some “sniper/precision rifle matches”.
Mods I plan in order;
1. Mount an optic: Bushnell tactical elite 10x scope, Weaver 20 moa base, TPS rings (low?)
2. Install a bipod: is there an acceptable substitute for a Harris: How about the Blackhawk bipods?
3. Trigger: If using the savage scout I would tune the trigger, so far I have replaced the spring and adjusted it but no sear face work? If using the Stevens I would buy/install a rifle basix (which one?) I have replaced the spring on this one but still tons of creep.
4. Check accuracy here.
5. Install the ER Shaw 20” tactical barrel (http://www.midwayusa.com/product/762...hreaded-muzzle) with a new stock. Currently thinking of a B&C Duramaxx?
Is one of these actions a better starting point than the other?

Thanks in advance.
