Hey anyone that shoots a Tac 15, I tried a broadhead that is called a Atom,
I did look at and research the Atom about a year ago. Two things came up with regards to the Atom. One was some reports of the Atom not cutting through deer-hide and flesh as well as normal razor blade tips. The other dealt with concerns on the Atom's durability when it came to hitting bone.
Before I went hunting any deer sized game with the Atom, I would personally want to test a couple of them on a rack of ribs (and if possible a shoulder joint) to see how they held-up and how they cut through. Reason being, the TAC-15 arrows are hitting with some incredible force; force that few non-crossbows can even come close to producing. Thus a broad-head that may hold-up on a 70lb / 300-fps compound bow, may not hold-up at all when shot from a TAC-15 into a medium (or larger) sized game animal.
