I really may have mislead you a bit on the 200 XTP. It is basically the same bullet as the SST/SW but it is tapered a bit more to allow the placement of the Polymere tip. The tip is placed into the cavity and besides adding BC it is suppose to aid in controlling the mushroom.
This is a Nosler but the Hornady is built close to the same way.
Hope this helps explain what I ment.
