Thought I would share some examples of what the Steelforce Phathead 100 has done for us.
Pic of the entry hole on a big 200+ lb boar shot by my partner Keith. The pic shows the 3/4" thick shield cut away, with the actual killing head held next to the cut shield.

Shot was 33 yards, and penetration was thru the shield and thru the far shoulder not quite thru the skin on the exit side. You can watch a quick clip of that kill at
YouTube - Keith's FL Boar if you like.
Next is a video clip of me killing two boars with one shot. Shot was about 5 or 6 yards. Passed thru the near hog and lodged in the second hog's far shoulder.

Just a couple reasons we love our Phatheads!
