I have both, and I can say, that on bolt lift a SSS T&T Savage has a lighter and has a smother feel than a Bat 2 lug. (Going by mine and a friends Bat actions) Sliding the bolt back the Savage will have a bit of slop do to the clearances, but if you bought a bolt body Dave Kiff (Pacific Tool and Gauge) it would remedy this problem. So to answer your question YES a SSS T&T action can be every bit as smooth as a high end custom action. (Bat, Panda, Hall, Nesika, ETC)
