Cut on contact 440B steel head with a blade thickness of .071 and a cutting dia. of 1 1/8".
Ferrule constructed of 7075 T6 Aluminum.
3pk. was $46.55 and replacement blades are $35.35.
(Ferrules are available as well)
The SilverFlame will be available in 100gr. but was not at the time of this test.

Flight:
Test bow: BK2
First impressions:
Out of the Package this head is awesome!
The thickness really catches your eye and the bevel that brings it all to the cutting edge really looks like it means to do some serious harm to something
And it does!
On inspection , I found that there was a wobble in the head when the shaft was spun.
It was so small that it took me a dozen times to assure myself that it was a real wobble and not just my eye's
Never the less , I attached a shaft lock , crushed it and re-checked....perfect.
-----------------------------------------------------------------------
First test flight was with the standard 200CX shafts which are very light for this head.
Best grouping was 0" to 1.5" .
Moving on to the 55/75 shafts (goldtip) with 10FOC the grouping tightened , better by 1" (0"-1") with no fliers.
I generally don't refer to noise because I rarely hear noise so I cannot comment on it truthfully.
But....
CHRIST!! .......this thing is like an ambulance leaving the scene of an auto accident!....damn! ~ LOL!
---------------------------------------------------------------------
Blade :
This is the first head ever to blow through a 100# PRO BAG and skip along the ground for another 8 yrds.
TWICE!
This thing is nuts!
Being so thick , I didn't expect anything great out of this head as far as holding it's edge and it took 12 shots to loose enough to be noticed.
Thats good by comparison to the majority
Anyway...on to the board!
It didn't make it through (and thats nothing new) but it did split it twice , from one end to the other over the distance of 12".
Blades were perfect afterward.
I was even able to use this head itself as a pry bar to dislodge it without damage to the ferrule after inspecting the blades to insure that there was no damage visible.
This is a very tough head!
----------------------------------------------------------------------
The final assault :
This was the forward shoulder of a 2 1/2 year old buck which was used for the testing.
ENTRY SIDE
EXIT SIDE
This didn't even seem to be a real challenge for this head but it did make contact on the heaviest area of the scapula.
It does not show in the Pic but the head actually jumped the raised bone below the entry/exit hole and then went through.
Blade damage was so minimal that it took probably 30 attempts to get a good Pic of the abrasion but here it is , best as I could get.
***NOTE
I have never cared about flight noise and have never held it against any head in the past so this would not keep me from passing this head.
...........CONCLUSION!........
PASS !

FLIGHT:
Another great day for testing in the tunnel
20m.p.h. gusts allowed me to really get a feel for what these heads were all about under these cross wind conditions.
Bows used were the BK2 @319fps(55/70 GT arrow)
and the
Reflex Grizzly @269fps (with same arrow)
With the 55/70 shaft FOC was 10% ...FPS dropped to 307
The BK2 caused these heads to react to any wind change with varying results.
Some shots were off by 2" around the clock.
I wasn't too displeased with some erratic flight , this is a very large head.
But...the manufacturer says "field point accuracy from any bow"
Well......maybe on calm days
So.....
Off to the Grizzly to see if it was the speed that was causing the problem
ShaZam!
With the heavier 55/70 shafts the hits were off point 1" or right on. (same as 2-24 test)
(Grizzly was tuned for this testing)
I have a few idea's about the different aspects surrounding the construction of this head and the fact that (to be fair) I may have to change a few things to get the combo where it should be for this head.
First off I am going to go to a three vane helical to get some spin on this head.
Test heads are shot 4 fletch w/1degree of offset to turn the arrow 2 turns at 30yrds.
While this may be fine for the heads that are most commonly used in testing , the mass of this head may well need a high rate of spin at longer distances.
Secondly , there is the weight forward issue and I will also test 15% FOC with the standard 4fletch to see if there is an improvement in grouping.
Tests were conducted with 200CX & 55/75GT
Ferrule constructed of 7075 T6 Aluminum.
3pk. was $46.55 and replacement blades are $35.35.
