A tahr shot is rarely the textbook shot. It is fired from kneeling on a tussock spur into a wind that has just shifted, after a stalk that has lifted your heart rate to 130 beats per minute, at a distance that requires you to dial your turret, on a bull who is moving from grazing to bedding in the next thirty seconds. Range time has not prepared you for this. Field practice has. This chapter is about that practice.
The honest baseline.
If you cannot consistently put a cold first shot into a 100 mm circle at 300 metres from a pack-supported prone position with no wind, you should not be hunting tahr. That is the entry point. It is achievable for any reasonably equipped hunter who puts in the range time. Without it, the animal you take is luck rather than skill, and the wounded animal you don't take is your fault.
If you can make that shot, you can hunt tahr. Everything beyond that — distance, position, wind — extends what you can ethically attempt.
Building the shooting position.
The shooting position you take in the field will rarely be prone over a flat range bench. It will be one of four:
Prone over a pack. The gold standard. Use it whenever the terrain allows. Lie behind the pack, rifle resting on the pack with the forend, shoulder firmly into the recoil pad, support hand under the rear stock or holding a small bag. Stable, low, fast.
Tripod-supported sitting. The most useful field position in tahr country. Use a hunting tripod with a Game Changer-style bag or an ARCA-clamp head and rifle saddle. Sitting with knees up, elbows resting on knees, rifle locked in the saddle. Stable enough for a 400-metre shot in moderate wind.
Tripod-supported kneeling. A higher version of the same, used when grass or scrub forces you off the ground. Slightly less stable. Workable for shorter shots.
Off-pack standing. Last resort. Pack jammed in tussock or atop a tripod, rifle over the pack, you standing behind. Use only when nothing else works and the range is short.
Practice these positions deliberately. A range session that runs prone-prone-prone is wasted preparation. Spend half your range time off the bench, in the positions you will actually shoot from.
The pre-shot routine.
When you reach your shooting position after a stalk, do not immediately fire. The bull is not going anywhere in the next two minutes. Your heart rate is at 130 beats per minute, your breathing is ragged, your hands are shaking from the climb.
The routine, in order:
- Get into position. Build the rest deliberately. Load. Safety on.
- Range the animal. Confirm distance.
- Check the wind. Note direction and speed at the shooter, mid-trajectory, and target if you can.
- Calculate the dope. Dial the turret or pick the holdover.
- Settle. Slow your breathing. Wait for your heart rate to drop. This takes three to five minutes minimum after a hard stalk; longer after a long one.
- Take the safety off, settle the crosshair, breathe out, take the slack out of the trigger, follow through.
A shot rushed is a shot wasted. Take the time. The bull is feeding.
Cold-bore shots.
The first shot of the day, cold-bore, may not group with the rest of the rifle's shots. Confirm your zero accounts for it. Some rifles' cold-bore land a quarter inch high; some a quarter low. Know yours.
In cold weather, point of impact can also shift slightly because of the cold barrel and the cold powder. Confirm zero in conditions resembling those of the hunt — early morning, cold rifle, cold range, before the day warms.
Long-range shooting
In the New Zealand alpine context, "long range" means anything beyond about 400 metres. Shots over 400 metres on tahr are sometimes warranted — the bull cannot be approached closer because of terrain, the wind is forecast to rise, the daylight is fading. Most are not. The default ethical shot is inside 400 metres.
The required tools.
You cannot make consistent 500–800 metre shots with a hunting rifle that holds 1.5 MOA, a 3–9× scope with a duplex reticle, and an estimated wind. You need precision-grade gear:
- A rifle that groups at sub-MOA off the bench with hunting ammunition.
- A scope with first-focal-plane reticle, MOA or MIL turrets, calibrated and confirmed.
- An accurate ballistics solver (Hornady 4DOF, Applied Ballistics, Strelok Pro). Use the actual measured muzzle velocity from your rifle, the actual ballistic coefficient of your bullet, and update for the day's atmospheric conditions.
- A rangefinder good for 1,500 metres or more, with angle compensation.
- A wind-reading method — mirage, kestrel, observed indicators.
The required practice.
Long-range shooting is a skill. It is not gear-buying. The hunter who buys an expensive precision rifle and a six-thousand-dollar scope and shoots only at 200 metres on the range is not a long-range shooter. The hunter who shoots steel at 500, 700, 900 metres in wind, off field positions, fifty rounds a week for three months is.
Range time in the off-season is what makes a 600-metre shot ethical in May.
The ethical line.
A shot you would take is a shot where:
- You can build a stable enough position to hold within a 6-inch circle for the entire trigger press.
- You are confident in your wind read to within 2 mph.
- You can range the animal within 5 metres of error.
- Your ballistics solver is calibrated and the rifle is zeroed.
- The animal is positioned where, if hit but mobile for ten seconds, it can be recovered.
- You have a fully-capable backup shot ready immediately.
If any of those is in doubt, the answer is to close the distance. There is no honour in a long shot. There is honour in a clean, recovered animal.
Wind reading in alpine basins
Beyond about 250 metres, wind is the dominant variable in your shot. Holding for elevation is mostly arithmetic; holding for wind is judgement, and the alpine basin is a judgement-rich environment.
The three zones.
Wind affects the bullet differently along its flight path. For long shots, conceptually divide the path into three zones:
Shooter zone. The first third of the bullet's flight, from muzzle to about a third of the way to the target. The wind here has the largest effect because the bullet is in flight longest under its influence.
Mid-trajectory zone. The middle third. Easily missed because it is the zone you cannot feel from your position.
Target zone. The wind at the target. Easier to read — you can see the grass moving, hair on the bull blowing — but contributes least to total deflection.
Read all three. The wind at your position can be calm while a thirty-knot cross-wind tears across the mid-trajectory two hundred metres above the basin floor. Mirage seen through the spotting scope tells you the mid-trajectory wind better than anything else.
Indicators.
Mirage. Heat shimmer through the spotter. Watch which way the wave is bending. Light shimmer means light wind; bending hard means strong wind. The single best mid-range wind indicator on a clear day.
Tussock and scrub. Grass leaning over and snapping back is somewhere in the 10 to 20 km/h range. Tussock heads steady but with stems flexing is 5 to 10. Tall tussock laid flat is 30 plus.
Snow blowing. Snow on faces lifting and drifting indicates 25-plus km/h winds at that altitude.
Lenticular and cap clouds. Strong upper-altitude winds; expect significant deflection on long shots.
The animal's coat. The mane on a bull standing broadside flutters at about 10 km/h, lays sideways at 15 to 20.
The wind formula.
The simple field formula for cross-wind drift, in MOA, is:
`(range in hundreds of metres × wind velocity in km/h × multiplier) ÷ 1000`
The multiplier varies by cartridge — call it 4 to 5 for a 7mm Rem Mag with a heavy bullet, 5 to 6 for a .308 with a 165-grain. A specific dope card built from your ballistics solver is more accurate. Memorise the cardinal numbers for your cartridge: roughly 1 MOA at 300 metres for a 10 km/h wind, 2 MOA at 500 metres for the same wind, and so on. Adjust by eye.
The doubt rule.
When uncertain, hold for the lower-cost miss. If the wind is unclear and the bull is broadside on a slope, miss high (over the back) rather than through the shoulder, because a high miss can be re-engaged whereas a wounded bull rolling down a bluff is gone. When in doubt about wind direction, pick the side of the rifle where a missed shot does not push a wounded animal into unrecoverable terrain.
When to wait.
Wind in alpine basins is rarely steady. It builds through the morning, often peaks mid-afternoon, drops at sunset, and dies overnight. If the wind is gusting unpredictably, sit for thirty minutes and read it. Often the gusts settle into a pattern with predictable lulls. Take the lull, not the gust.
If the wind is rising and the bull is feeding, take the shot now — in fifteen minutes the wind will be worse. If the wind is dropping, wait — in fifteen minutes the shot is easier.
Bullet placement on tahr
A clean kill on a tahr is heart-and-lung, broadside or slightly quartering away, behind the front shoulder.
Heart-and-lung is the default. A through-shot that exits the off-shoulder leaves a bull dead within twenty seconds. Use this whenever terrain and angle allow.
Neck-and-shoulder is the option when the bull is on terrain where a wounded animal cannot roll into unrecoverable ground. The shot anchors the animal in place. The cape is slightly more damaged at the shoulder; the trade-off is recovery.
Quartering shots. The bullet must drive forward through the chest cavity along its exit path. A quartering-away shot at the rear of the broadside ribcage drives the bullet diagonally forward and is effective. Quartering-on shots at the brisket are more difficult and more likely to wound than to kill.
Head shots. Avoid. The horns and skull are the trophy. Head shots ruin both more often than they are clean.
The follow-up.
After the shot, watch the bull through the scope. The four reactions:
- Hump and stagger. Heart shot. The bull hunches and falls within 10 to 20 metres. Expected.
- Run-and-fall. High lung. The bull runs hard for 50 to 150 metres, slows, stops, falls. Expected.
- Stand-and-fall. Spine or neck. Down on the spot. Expected.
- Run hard with no reaction. You missed. Re-acquire and shoot again.
Reload immediately, regardless of which reaction. Be ready for a follow-up shot on a recovering animal. Most second shots in tahr country are unnecessary; the ones that are necessary are needed within five seconds.
Gear that makes shooting easier.
- A bipod for prone — Atlas, Harris, Spartan all good.
- A field tripod (Two Vets, Spartan Davros, Outdoorsmans) for sitting and kneeling shots.
- A rear bag (Game Changer-style) for any rest situation.
- A suppressor if legal in your home jurisdiction; legal and standard in NZ. Reduces recoil and protects hearing.
- A wind meter (Kestrel) if you can carry one. Anchors your wind estimate.
- An accurate ballistics card on the rifle, taped to the stock or in a buttstock pocket.
The most important point.
The shot is the tip of the iceberg of preparation. Range time, dry-fire, position practice, gear setup, ballistics work — all of these are done before the trip, not on it. The hunter who arrives in NZ believing the hunt will teach them to shoot is the hunter who wounds an animal. Do the work at home. Make the shot in the field.
