Broadhead

A broadhead is a bladed arrow point designed for hunting — its cutting edges create a wound channel that causes lethal hemorrhage rather than the blunt puncture of a field point. Broadhead designs divide into three categories: fixed-blade, mechanical (expandable), and hybrid, each with distinct trade-offs in reliability, trajectory, and wound-channel size.

Details

Fixed-blade broadheads have blades permanently exposed — there are no moving parts to fail. Their simplicity makes them the most reliable choice in bone-contact or quartering-toward shots where a mechanical could fail to open or be knocked off-course. The challenge with fixed blades is aerodynamic: exposed blades act like fins and will amplify any tuning flaw in the bow or arrow. If your field points group well but fixed-blade broadheads scatter, the bow needs further tuning — paper, walk-back, or bare-shaft — before the broadhead is at fault. Accuracy with fixed blades is a tuning test, not a broadhead problem.

Mechanical broadheads have blades that fold back and deploy on impact. In flight they present a nearly field-point profile, which is why they typically impact very close to where field points hit with no additional tuning. Their wound channels are often larger than fixed blades due to the deployed blade diameter. The tradeoffs are energy consumption on deployment (the blades opening absorbs kinetic energy that would otherwise drive penetration) and the possibility of mechanical failure on a bone-contact shot. Lighter, faster setups favor mechanicals; heavy, FOC-optimized hunting builds often favor fixed blades precisely because they have extra momentum to spare.

Hybrid broadheads combine a permanent fixed-blade with smaller secondary blades that expand on impact. The fixed blades provide initial cutting and ensure the head tracks straight regardless of tuning variation; the expanding bleeders add wound-channel width. Designs from Iron Will and Day Six Bowhunting represent this category. Hybrids are a reasonable compromise for hunters who want fixed-blade reliability on bone without fully sacrificing wound-channel size — but they still require adequate tuning before the fixed-blade component tracks predictably.

Broadhead weight interacts directly with FOC and tuning. A 100-grain broadhead is the standard reference weight — spine charts are built around it, and most bow setups are tuned to it. Switching to a 125-grain broadhead on an arrow built around 100-grain points increases FOC and weakens dynamic spine; you may need to re-tune or re-select shaft spine. Many hunters standardize on one broadhead weight for this reason and use insert weight to adjust FOC rather than swapping head weights.

Häufige Fragen

Should I use fixed-blade or mechanical broadheads for hunting?: Both work when properly matched to the setup. Fixed blades are preferred for heavy-cover shots, steep quartering angles, and hard-bone contact situations because they cannot fail mechanically. Mechanicals excel when trajectory matching with field points is critical — close-range tree-stand hunting with a well-tuned bow, for example. If your arrow's total weight and FOC are already optimized for penetration, fixed blades are generally the more reliable terminal choice at the expense of extra tuning effort.
Why don't my broadheads fly where my field points do?: Fixed-blade broadheads plane in flight just like arrow vanes — they respond to the same aerodynamic forces. Any form, timing, or spine issue that field points tolerate will be amplified by exposed blades. Start with paper tuning to confirm a bullet hole, then do walk-back tuning at 20–40 yards to verify point of impact consistency. Once the bow is tuned for field points, broadheads will typically group within a few inches; if they still diverge, check broadhead blade alignment and consider switching to a mechanical or hybrid.
Should I shoot 100-grain or 125-grain broadheads?: 100 grains is the most compatible choice — spine charts, tuning guides, and component recommendations assume a 100-grain point unless specified otherwise. If your FOC target requires more front weight than a 100-grain point provides, increasing insert weight is preferable to switching to a 125-grain broadhead, because it avoids the spine and trajectory shift. Hunters pursuing very large or dangerous game sometimes use 125 or 150 grains as part of a deliberately heavy, high-FOC setup — but this requires a spine and tuning recalculation from scratch.
