The colors of the broadheads may have changed. As I recall these were purchased in early 2008. After rebeveling, the heads typically weigh just under 160 grains. They have 100 grain steel adaptors and are assembled with JB Weld. Blackhawk Vapor 4000s with 100 grain brass inserts put the finished arrow just over 650 grains. My LH Sovereign Archery Ballistic Recurve draws about 50 pounds at my 27ish draw length. This combo has produced excellent penetration but I have wondered about the durability of the broadhead on a heavy bone hit. This experience sure was impressive. Thank you Dr. Ashby for all of the insight and Jason for spreading the word.
