The shot-execution sub-skill specific to bowhunting mule deer — distance discipline, broadhead-only practice, cold-arrow first-shot training, draw timing, in-the-moment heart-rate management, and bow tuning protocols. Distinct from rifle execution because the arrow's flight characteristics, energy budget, and shooter physical state introduce failure modes that don't exist with a rifle. "All they have to do is take a step and it can turn into a rodeo." — Dioni Amuchastegui
The bowhunter has a self-imposed maximum range tuned to his realistic field accuracy (Randy Ulmer's 60 yards is the canonical default; Marlon Holden extends to 100 only on high-volume year-round broadhead practice). He practices exclusively (or near-exclusively) with broadheads, recognizing that field-point groups don't predict broadhead impact at distance. He shoots cold — first arrow of any session at the longest distance — because hunting reality is a single first shot. He tunes his bow on paper and through-air, treating machine tunes as grouping diagnostics only. In the field, he does not draw until the shot window is imminent; arms tire and shake quickly. When adrenaline spikes pre-shot, he uses an explicit calming routine (binoculars, photo, breath count) at full or partial draw to reset heart rate. He practices off the ground, kneeling, awkward angles, and uphill/downhill rather than only level-range standing. He builds a stable shooting position (rocks moved, snow dug, sticks cleared) before any long-range shot.
The dominant industry message is "field-point groups predict broadhead groups if your bow is tuned." This is false at hunting distance. Broadheads have larger frontal area, create more drag and lift, and exaggerate every tuning error and inconsistency. Hunters who practice with field points all summer arrive at season with no honest data on their hunting setup. Marlon Holden practices only with broadheads, year-round, and has high one-shot kill ratios as a result.
Hunting is a first-arrow event. The hunter doesn't get to warm up. He doesn't get a sighter. He gets one cold-muscle arrow at an unknown distance, often after stress (a stalk, an uphill push). Volume practice with warm-up arrows trains the wrong system. The cold-arrow protocol — one shot per session at max range, after physical stress, with a broadhead — is the only practice that maps to the hunting reality.
Adrenaline destroys more bow shots than wind, range, or tuning. Without a deliberate calming routine, heart rate spikes to 140+ and mechanics collapse. Marlon Holden's protocol — at the moment of high pressure, before drawing, pull out a camera or binoculars and look at the buck for 30–60 seconds — exploits the calming effect of a micro-distraction. The shooter's focus shifts from "I have to kill this animal" to "I'm looking at a buck," which drops the adrenaline curve.
Marlon Holden uses Arizona OTC December–January any-antler hunts (mule deer + Coues) for high-volume realistic-feeling rep building. Seventy-plus deer sightings in two days is possible. The kill is not the point — the encounter rate is. The hunter who has put hands on a bow with a mature buck at archery range 50+ times has wildly more execution capability than the hunter who hunts only one or two tags per season.
Most archers reach the shot position, then improvise the shooting platform — kneel where it's convenient, brace where they can. The result is unstable mechanics under adrenaline. Top hunters build the shooting position deliberately, often minutes before the shot — moving rocks, digging snow, clearing sticks, positioning their body precisely. The position-building is part of the stalk, not separate from it. Same principle Dioni applies on his rifle hunt ("my position is at least as good as if I'm going to shoot at a target") translates to archery: prepare the platform before the buck is in your shot window.
