So if you match your picture with the first picture in the post, it would be a Hornady Interloc. That would be the correct bullet not a Sierra.It's a Sierra 165gr, the cannelure on the Hornady Interlock is lower. The Interlocks also have more of a secant ogive than gamekings that have a tangent ogive. See attached image of a 160gr Sierra Gameking (left) and a162gr Interlock (right) for comparison.
