If those are "old Stock" they may not appear on Bergers current website. In the Begining all Bergers were in yellow boxes. Today they are in yellow, orange and tan boxes. Generally the target versions simply have a little thicker jacket, only a few thousands. In some cases I have found these to be very desirable for hunting. In some chamberings a little less expansion on closer shots is not a problem. So, depending on your intended muzzle velocity and average shot distance these could be exactly what you want for hunting. However, if you call Berger they will go with their code and tell you they are not intended for hunting. Last season we killed 19 big game animals from 200 yards to 1285 yards, with the Berger "target bullet" from the same 300 win. All one shot kills and none traveled but a few steps. So this is something you need to decide from what you know about your rifle, load, shot distances, and size of game you are after.
