775 Grain Single-bevel Broadheads (Mega Pack – 6 broadheads, 6 field points)
$49.95
world’s heaviest broadhead.
From high-powered crossbows like the Tenpoint RS470, it flies about 300 FPS, generating roughly 220 ft-lb of kinetic energy and 1.5 slugs (48 lb/ft/sec) of momentum. For comparison, the .308 Federal Ballistic Tip 150 grain bullet generates 60 lb/ft/sec of momentum, so 80% of that, and the .308 isn’t a 2-inch wide blade.
While not discounting accuracy and shot placement, momentum is the most important measurement of broadhead lethality, since it determines the likelihood of achieving a passthough though all obstacles, including thick hide and bone.
When shooting fixed blade broadheads, particularly one this large, accuracy is always a concern. In testing thus far, the Edgetac 775 achieves 1-2 inch groups, at 30 yards.
To achieve accurate flight with this broadhead, having a sufficiently stiff arrow is mandatory, and using fletchings that exert maximum drag and control may be key factors, depending upon your bow. Maximum drag and control fletchings might include something like 5-inch feathers at 1.5° offset for crossbows, and the same fletching at 5° helical for vertical bows.
In addition, it’s generally believed that about 280 FPS is an ideal speed for tuning and shooting fixed blade broadheads, so that’s something to consider when selecting arrows and inserts.
For crossbows, we recommend double-shafted arrows to eliminate excess archer’s paradox. For vertical bows, we recommend the Black Eagle Rampage 150 spine. Standard crossbow arrows, including the popular Black Eagle Executioner, are not stiff enough, and standard factory vanes do not exert sufficient drag and control to achieve accurate flight.
For those considering shooting this broadhead from a vertical bow, a 28.25-inch Black Eagle Rampage 150 spine, with a factory nock, and Bearpaw 4″ shield cut feathers at 5° helical, total arrow weight of about 1300 grains, achieved accurate results.
This broadhead is CNC machined, not forged, from a solid block of steel.
Versus regular broadheads:
– Generates 82% more momentum*
– Double the cutting width
– 3X the blade thickness
– 7X the mass
Shot placement is still critical to any successful hunt.
Comes sharp from the factory.

Description
*Energy comparison vs standard 100 grain broadhead:
(shot from Centerpoint Sniper 370 crossbow)
Light arrow (Black Eagle Executioner 22 inch arrow + 100 grain broadhead):
431 grains, 348 FPS, 0.66 Momentum, 116 KE
Heavy arrow (Black Eagle Executioner 20 inch arrow + 16 inch carbon arrow insert (7.5mm OD) to increase stiffness + Ethics Archery 200 grain .300 Adjustable Static insert + Edgetac 775 grain broadhead):
1353 grains, 200 FPS, 1.20 Momentum, 120 KE
Kinetic energy increased by 4%, while momentum increased by 82%. Achieving an 82% increase in momentum is one of the primary advantages of using a high mass arrow-broadhead combination. This level of momentum maximizes the probability of a passthough and a clean kill.
Arrow stiffness & accuracy:
Extra-stiff arrow shafts are crucial to achieving accuracy with this broadhead. Standard arrows will flex excessively and accuracy will suffer. The more powerful the bow, and the longer the arrow, the greater the need for stiffness to maintain accuracy. Archers may select a stiff arrow such as the Black Eagle Rampage 150 spines or the Grizzlystik TDT 170 spines. If you an archer and need assistance with arrow selection, Rob Hummel at Dynamic Archery Solutions (not affiliated with Edgetac) can assist. Rob has set up and shot Edgetac 375 and 775 grain heads accurately from his bow.
For crossbows, enhanced stiffness bolts can be constructed by taking standard crossbow arrows, which have an inner diameter of 7.62mm, and inserting carbon archery arrow blanks with an outer diameter of about 7.54mm.
Trajectory example:
A Centerpoint Sniper 370 crossbow will shoot a 1353 grain arrow (Edgetac 775 grain broadhead, 572 grain arrow) at 200 FPS. Assuming a zero of 15 yards, here is the drop at various distances:
| 775 grain broadhead | 100 grain broadhead | |
|---|---|---|
| Distance (yrd) | drop (inches) | drop (inches) |
| 15 | 0 | 0 |
| 20 | 4 | 0 |
| 25 | 9 | 1 |
| 30 | 17 | 3 |
| 35 | 28 | 6 |
| 40 | 40 | 10 |
| 45 | 55 | 14 |
| 50 | 72 | 19 |
| 55 | 92 | 25 |
| 60 | 113 | 32 |
| 65 | 138 | 40 |
| 70 | 164 | 49 |
| 75 | 193 | 58 |
| 80 | 224 | 69 |
| 85 | 258 | 80 |
| 90 | 293 | 92 |
| 95 | 332 | 105 |
| 100 | 372 | 119 |
For crossbows a scope with built-in drop calculations is recommended:
Sig Sauer BDX Sierra6 2-10X
Sig Sauer BDX Sierra3 2.5-8X
Garmin Xero X1i Rangefinding Scope
Burris Optics Oracle X

775 Grain Single-bevel Broadheads (Mega Pack - 6 broadheads, 6 field points)
Surprisingly accurate but you need ultra stiff arrows and big helical feathers. Highly recommended!
