There are two versions, one slug/buck and another with the segmenting slug described by the O/P
wow that cool. Do you have any links to the segmenting round, that sounds like it would be a fairly good round for close range deer.
Shot placement is everything! I would rather take a round of 50BMG to the foot than a 22short to the base of the skull.
all 25 of my guns are 45/70 govt, 357 mag, 22 or 12 ga... I believe in keeping it simple
