I've been building rifles on Savage actions for about 7 years now. All standard calibers on the 10/110 action are small shank barrels. As stated previously, WSMs and target actions will have the large shank. You can tell a large shank barrel by the step down just in front of the barrel nut.
I found I can outshoot many Remington 700s with my builds. I can achieve groups of slightly more than one inch at 400 yards with the 168 gr Match King in my 308 that is barreled with a stainless 1 inchl bull barrel at the muzzle, made by Kreiger. I recently went to the B&C tactical stock with the bedding block and have not found any reason to glass bed since I went to it.
