Question: Are the blades included or is this just the head?
Document: Read one complaint about losing blades when shooting so first thing I did was check the screws holding the blades. One screw each on two arrowheads and two screws on the third were very loose. After tightening, I went hunting. Only shot one so far. Did not fly exactly like my field point but closer than a conventional fixed broadhead. Blades opened properly and left large entry and exit holes. Recovered with no damage to head or blades.
Still haven't shot live game yet but hope to ASAP. Deadly on targets, even from a 400 fps crossbow. Golfball sized groups at 40 yards, baseball sized at 70 yards (albeit with custom arrows). Five stars may be not enough if it cuts and bleeds deer like I've been told it will.I sacrificed one head to use for practice, and it really held tough. It only got erratic after several dozen shots.The blades are literally shaving sharp and fairly thick.
Worked perfectly - they roll up the shaft upon hitting the target. Then the blades opened.
Amazing broadheads.They really do fly just like field points! Never had a problem with deployment of blades(by the way they slice a HUGE hole) and the rubberband has always still been on the arrow(if you lose it though don't worry they give you a big baggy of extras)The only downside to these broadheads is that they are really only good for one use. After passing threw deer they they are extremely dull and so small they are difficult to sharpen.
In hunting, they have performed fantastically on 4 deer. The tip is very sharp and smashes it's way through bone with ease. The penetration was awesome with 4 complete pass through shots that left a blood trail that a blind man could follow! But I've never had to follow one more than 50 yards! The entry and exit wounds are massive! I really like the way these blades deploy compared to the "over the top" deployment of other mechanical broadheads. virtually no lost energy in deploying the blades.
very Accurate
These arrow heads are great. They always open on impact and cut even bow. They cause a great damage to make quick kills.
I was a die hard fixed blade man for 25 years of bow hunting, but I finally gave in and started trying mechanical broadheads two years ago. I probably tried 5 or 6 different types and did not like them and was about to give up when a recommendation from a close friend landed me on the meat seeker. In practice, they are so close in flight to regular field tips, I didn't bother making any adjustments to my bow.
I shoot 295 fps, complete pass-thru every time. Massive entry and exit wounds, and fly just like a field tip.
I have shot these for 4 seasons now and love them. These create a large entrance and exit hole. You'll be impressed after shooting one time.
