To start, there is a difference in short action and long action bolt heads. To use a 223 on a long action you need to either find one of the old 223 long action bolt heads, (Like finding a needle in a hay stack.) or use a Sharp Shooters supply conversion, to use a short action bolt head on a long action. The 22BR would use a standard .473 bolt head. (Like used on a 30/06, 270 308 ETC.) The other thing is with the simplicity of the Savage design there is no need to have two bolts, it should only take you an extra 5 minutes to change out the bolt heads. Also to add it is easier than finding a bolt that will properly fit your action, or making an second bolt fit properly.
