The best broadheads for a 400 fps crossbow

The failure mode is specific. At high velocity the air load on a mechanical's exposed blade edges is greater, and a rubber shock collar or O-ring holding those blades closed is a consumable part under more stress than its designer assumed. When it lets go in flight, the head opens before impact — accuracy is gone and the arrow is dangerous.

TenPoint EVO-X Montec

TenPoint

8.8/ 10

Built for TenPoint by G5, which is to say it is a Montec specified for high-speed crossbows: 100 grains, three fixed blades, a 1-1/8 inch cut, one-piece MIM construction and a 100 percent steel ferrule. If you shoot a fast bow and want a fixed head, this is the one that was designed for the application.

Published spec	Value
Weight	100 gr
Cutting diameter	1-1/8 in
Blades	3, fixed
Construction	One-piece MIM, 100% steel ferrule
Designed for	High-speed crossbows
Sharpening	Diamond cut
Per pack	3

What it does well

• Specified for high-speed crossbows, not adapted from a compound head
• One-piece construction with nothing to come loose
• Made by G5, whose Montec is the reference fixed head

Where it falls short

• A 1-1/8 inch cut is narrow by mechanical standards
• Costs more than the standard Montec for the same geometry

Rage Hypodermic Trypan NC

Rage

8.6/ 10

A one-piece titanium ferrule, .039-inch stainless blades, a hybrid tip and No Collar retention — meaning the blades are held closed by the ferrule geometry rather than a rubber band you have to replace every shot. For a fast bow, the collar is the part that fails, so removing it matters.

Published spec	Value
Weight	100 gr
Blade thickness	0.039 in
Type	Mechanical, expandable
Ferrule	One-piece titanium
Retention	No Collar
Tip	Hybrid
Per pack	3

What it does well

• No Collar retention removes the consumable rubber band
• A titanium ferrule is lighter and stronger than aluminum
• .039-inch blades are thick for a mechanical
• Ferrule alignment adapter helps it spin true

Where it falls short

• Most expensive broadhead here
• No cutting diameter published on this listing
• Mechanicals lose energy opening, which matters on a slow bow

Grim Reaper X-Bow Razor Cut

Grim Reaper

8.3/ 10

A 3-blade mechanical with a 1.5-inch cut on a one-piece stainless tip, and the listing states it is engineered for crossbows and stable to 400 fps. That speed statement is the thing to look for: plenty of mechanicals are sold for compound bows and come apart at crossbow velocity.

Published spec	Value
Weight	100 gr
Cutting diameter	1.5 in
Blades	3
Type	Mechanical
Rated speed	Up to 400 fps
Tip	One-piece stainless steel
Accuracy claim	Field-point accuracy to 100 yd

What it does well

• A published speed rating, which most broadhead listings omit
• A 1.5-inch cut from three blades
• A one-piece stainless tip holds an edge through bone

Where it falls short

• 400 fps rated, so it is not the choice for a 430-470 fps bow
• Expensive per head
• Mechanicals need a bigger entry hole than a fixed blade

G5 Montec 100 gr

G5 Outdoors

8.9/ 10

One-piece metal-injection-molded steel with a 1 to 1-1/8 inch cut, cut-on-contact geometry and every head spin-tested before it ships. There are no blades to replace, no screws to loosen and no collar to fail. For a fast bow, a fixed one-piece head is the most reliable thing you can put on the front of a bolt.

Published spec	Value
Weight	100 gr (85 and 125 also offered)
Cutting diameter	1 to 1-1/8 in
Blades	3, fixed
Construction	One-piece MIM steel
Sharpening	Diamond cut, cut-on-contact
Quality control	100% spin-tested
Per pack	3

What it does well

• One piece: no blades, screws or collars to fail
• Every head spin-tested before it ships
• Resharpenable, so a head survives more than one animal
• Cut-on-contact geometry starts cutting immediately

Where it falls short

• A 1-1/8 inch cut is narrow next to a 2.25-inch mechanical
• Fixed blades plane more in wind than a closed mechanical
• Needs careful tuning to fly with field points

Muzzy Trocar HBX Hybrid

Muzzy

8.3/ 10

Four blades: two fixed, two mechanical, with the fixed pair offset to induce spin. It is a genuine middle path — the fixed blades cut on contact and the mechanicals widen the channel, and the chisel tip and stainless ferrule are built to survive bone.

Published spec	Value
Weight	100 gr
Blades	4 (2 fixed, 2 mechanical)
Type	Hybrid
Tip	Chisel
Ferrule	Stainless steel
Design note	Offset fixed blades induce spin
Cutting diameter	Not published

What it does well

• Fixed blades cut on contact even if the mechanicals do not open
• Offset fixed blades stabilize the arrow in flight
• A stainless ferrule and chisel tip for bone

Where it falls short

• No cutting diameter published
• Four blades mean more drag and more wind planing than a 2-blade
• More parts to inspect before every hunt

How we picked

Published speed rating where one exists; otherwise a design that structurally cannot deploy early. One-piece construction and collar-free retention both qualify. See our methodology.

Why each one is suitable

What else changes above 400 fps

Your target

Most bag targets stop at 425 fps. A 430 fps or 470 fps bow needs the Rinehart 18-1 (500 fps) or the SpyderWeb 20XL (no stated limit). And you need a broadhead-capable target for the pre-season check, which is a separate purchase from your practice bag. See targets for fast bows.

Your bolt tolerances

A small initial error has more flight time to grow at higher speed. Straightness goes from a nicety to something worth paying for: the Carbon Express Maxima Contour publishes .002 in as a maximum, and TenPoint's CenterPunch16 publishes .001 in.

Your nocks

Nock fit matters more because string-to-nock engagement is doing more work. Alpha-Nock and V-Track systems both exist to address exactly this, and a worn or loose nock on a fast bow is a flier waiting to happen.

Your arrow weight

A heavier arrow is slower, quieter and carries more energy, and 400 gr complete is the mainstream answer. Chasing peak fps with a light arrow on an already-fast bow buys a flatter trajectory and costs noise, penetration and margin.

What to avoid above 400 fps

• Heads designed for compound bows, however good. The speed is the problem, not the quality.
• Shock-collar mechanicals unless the maker publishes a crossbow speed rating.
• Very wide cuts on thin blades. More air load, more resistance, more to go wrong.
• Mixing arrow weights. Your scope's speed dial is set for one velocity.

What we would buy

The TenPoint EVO-X Montec if you want nothing to think about: one-piece steel, specified for the application, 1-1/8 in cut. The Rage Trypan NC if you want a mechanical's wound channel without a consumable retention part. The Muzzy Trocar HBX if you want the hybrid insurance that there is no such thing as a total deployment failure.
