Target rifle build .308

[GSXR]

Wanting some feed back on my idea for a rifle build. first ill say that I do reload. My current gun Is a law enforcement model 10. Accutrigger and stock 20" barrel .308 Im a 1/2 moa shooter on my better days and im sure the rifle is way better than that. I wanting to build a rifle with a longer barrel to get better velocity from my loads. Im thinking about going with a savage .308 target action and a Shilen 28" 1:10 stainless select match barrel. What stocks out there fit the savage target action with no mods needed other than say a little clearance work with a dremel at most. Dont know much about the target action and cant seem to find much info on it. now this rifle will be used for nothin but shooting off my bench so i dont care about how heavy or ugly it is etc etc. I care about what happens on the other end only and before someone suggest all the custom stuff thats way better please keep in mind that this is what I can afford which is why Im asking about it and yes im aware there are better calibers out there than a .308 , but .308 is what im going to use so please lets keep the thread on topic. Now savage makes a target bench gun with a heavy 29" barrel. The twist rate is the major turn off to me. I know the 1;10 will stabalize 190 and 200 stuff so the 1:12 on there factory rifle doesnt appeal to me for this reason alone. Ive also heard they dont do anything different on there target barrels than say whats on my le model no?, so basically your still getting a mass factory barrel. BUT... how good are the savage target rigs out of the box?? buying the completed rifle savage offers would definately be cheaper or does my build: savage target action right load right eject I shoot left handed and the heavy contour shilen with the 1:10 twist at 28 inches and a mid level stock sound like the ticket for better accuracy. I have alot of cross wind where i shoot and I like the heavier bullets for obvious reason but want to keep the velocity up. basically i want the best accuracy for what I can afford to spend which is pretty much the two options that I have listed.
