I did find it necessary to have something for re-coil, with the 20 inch barrel shooting 308.
I used a bag of sunflower seeds - basically like sandbags, but much lighter. Made them for shooting on wild land (away from fancy stuff like front shooting rests). An athletic sock filled with sunflower seeds, tied off with wire.
But with the 24 inch barrel, the 308 is a completely different beast. (higher velocity, much less recoil)
I like the Savage rifles too.
