The savages were the first real projects I got into with changing out barrels and such. I have built several guns on them all were 110 actions. I have used pre-fit barrels from Pac-Nor,Shilen,Sharp Shooters Supply,Kevin Rayhill , E.R. Shaw , Lothar Walther and I have fitted a few myself setup like the Rem's , all shot very well. One of my favorite things to do was buy a heavy 223 1-9 twist barrel then rechamber it to 22-250 Ai , they all shot the 69gr SMK awsome especialy if you firelapped them first as a 223.
I have used triggers from SSS , and Rifle basix both with awsome resluts. I got to talk to Kevin Rayhill at length about "timing" the Savage actions and got the whle idea down and did it to a few but never realy saw where it was that big of a gain to accuracy.
The Prefit barrel from Shilen that Brownells offers is a great deal I bought one , a #7 conture in 308 that would shoot just about all loads under an inch and it was easy to find loads with bullet from 155 to 210 that would shoot under 1/2moa out to 500yds , the barrel I got was acctualy chambered pretty tight and would have a stiff bolt close on factory ammo.
All in all I think that for the money the Savage/Stevens actions are realy hard to beat for a low budget build. I'm still not realy crazy about the seperate "floating" bolt head but I realy can't find fault with it. and it can't be that bad as from the pics I've seen its the exact same desgine that Armalite uses on their big 50 BMG bolts.
