Sighting In Before You Fly to a Remote Alaska Camp
There’s nothing quite like the feeling of anticipation before an Alaska hunt, knowing you’re about to fly into some of the wildest country on Earth. But that excitement can quickly turn to a gnawing worry: did my rifle survive the journey? A shifted zero is every hunter's nightmare, especially when you're headed to a remote camp with no range in sight. This guide will walk you through the essential steps to ensure your rifle is perfectly sighted in before you ever board that bush plane, and what to do once you’re on the ground, so you can hunt with confidence.
Why a Precise Pre-Flight Zero is Absolutely Critical
The stakes are incredibly high when you're hunting in Alaska. Unlike many lower-48 hunts, you often don't have the luxury of returning to your truck for another box of ammo, or popping into a local sporting goods store for a quick range session. Your rifle, your ammunition, and your ability to place an accurate shot are your lifelines, not just to success, but often to ensuring a quick, ethical kill and a safe trip home. The moment you step off that plane, whether it's a Super Cub on a gravel bar or a floatplane on a remote lake, you are effectively in the field, and your gear needs to be ready.
The Cost of a Missed Opportunity
Imagine spending months planning, thousands of dollars on licenses, tags, and airfare, enduring grueling physical training, and finally spotting that trophy bull moose or full-curl ram. You’ve put in the work, made a perfect stalk, and the animal is standing broadside. You settle in, take a breath, squeeze the trigger, and… nothing. Or worse, a clean miss, or a wounding shot that sends the animal fleeing into impenetrable cover. That single moment, born from a rifle that isn't true, can shatter an entire hunt. It's not just the financial loss or the disappointment; it’s the ethical responsibility to make a clean kill that weighs heaviest on any Alaskan hunter.
Ethical Imperatives in Big Game Hunting
Beyond the personal disappointment, there's a profound ethical responsibility when pursuing big game, especially in Alaska. Wounding an animal and losing it is a failure that no hunter wants to endure. It's disrespectful to the animal and the resource. A truly ethical hunter prioritizes a quick, humane kill above all else. This means not only being proficient with your rifle but ensuring that weapon is performing precisely as it should. A solid zero before you even leave civilization is the foundation of that ethical approach, minimizing the chance of an unfortunate outcome in the vastness of the Alaskan wilderness.
The Realities of Air Travel and Rifle Zero
It’s easy to assume that if you pack your rifle in a good hard case, it’ll be fine. And often, it is! But "often" isn't "always," and when your hunt depends on it, you can't afford to leave things to chance. Air travel subjects your valuable hunting rifle to a surprising amount of stress and potential for impact, even if it's handled with care.
Hard Cases Aren't Always Perfect Protection
While a high-quality, airline-approved hard case is absolutely indispensable for protecting your rifle, it’s not a magic shield against all forces. These cases are designed to absorb impact, but extreme jolts can still transmit energy to your scope's internal components or even slightly bend a barrel. Imagine your case being dropped off a conveyor belt, or sliding off a baggage cart – these aren't rare occurrences in the fast-paced world of airport logistics. Even small, seemingly insignificant shifts in your scope's zero can lead to significant discrepancies at longer ranges, turning a vital shot into a disheartening miss. A good rule of thumb is to treat your rifle in its case like a fragile package, even though airlines won't.
Airline Handling and Transfers
The journey from your home to a remote Alaskan air strip often involves multiple transfers, especially if you’re coming from the Lower 48. Each transfer means your rifle case goes through another round of loading, unloading, and potentially rough handling by different crews. It might sit on different tarmac surfaces, experience various temperatures, and be jostled alongside countless other pieces of luggage. Even if the initial airline is meticulous, a connecting flight with less careful handlers could be the one that bumps your zero. This cumulative effect is why trusting a pre-flight zero blindly is a gamble many experienced Alaskan hunters refuse to take. This is especially true when working with an Alaska transporter pilot for a fly-in hunting trip, as they have strict rules about gear and weight.
Temperature, Pressure, and Altitude Changes
While modern optics are generally robust, the significant changes in temperature, pressure, and altitude that accompany air travel can put subtle stresses on a scope’s internal mechanisms and the rifle's components. Going from a warm, sea-level garage to a cold, high-altitude bush plane at 10,000 feet, then back down to a chilly river bar, creates expansion and contraction that can potentially affect delicate adjustments. While these changes usually don't cause a drastic shift, they can contribute to minor deviations from your perfect zero. It’s another layer of uncertainty that makes a post-travel check invaluable for peace of mind and ethical hunting.
Best Practices for Pre-Flight Sighting In
Okay, so you understand why this is important. Now let's talk about how to get it done right before you even think about packing that rifle for your flight. This isn't just about sending a few rounds downrange; it's about a methodical, precise approach that builds confidence.
Choosing the Right Range and Conditions
First and foremost, choose a range that allows you to shoot from a stable bench rest at the distances you expect to hunt. For most big game in Alaska, a 200-yard zero is a great starting point, giving you a very manageable holdover out to 300-350 yards for many common cartridges. If your range doesn't have 200 yards, a 100-yard zero is perfectly fine, just be sure to know your ballistic drop at longer ranges.
Crucially, shoot in conditions that mimic, as closely as possible, what you might encounter in the field. Avoid shooting on a perfectly calm, indoor range if you know you’ll be hunting in wind and rain. Pay attention to ambient temperature. The goal is to eliminate as many variables as possible during your zeroing session. Take your time, let the barrel cool between shots, and ensure your shooting technique is flawless. If you're heading to the coast, considering how your Archery Tackle That Survives Ten Days of Rain is a good parallel for rifle readiness.
Ammunition Consistency
This might sound obvious, but it bears repeating: zero your rifle with the exact ammunition you plan to hunt with. Don't practice with cheap plinking rounds and then swap to premium hunting loads at the last minute. Different bullet weights, designs, and powder charges will impact point of aim and point of impact drastically. Buy several boxes of the same lot number of your chosen hunting ammunition and use it exclusively for your zeroing, practice, and the actual hunt. If you're on a multi-species hunt, ensure you have enough of the specific ammo for each firearm. Many experienced hunters will bore-sighting in camp without a range as a last-ditch effort if their zero is off, but nothing beats knowing your hunting ammo precisely.
Proper Shooting Technique and Form
Even the most accurate rifle needs a solid foundation. When zeroing, ensure you are using proper shooting form. A solid, repeatable rest (sandbags, bipod, lead sled, etc.) is essential. Focus on breath control, trigger squeeze, and follow-through. Don't rush your shots. Remember, you're not just confirming the rifle's zero; you're also confirming your ability to shoot it accurately. Any flinch, jerk, or rushed shot can artificially shift your perceived point of impact. If you're unsure about your form, consider getting a quick lesson from a reputable instructor. This foundational skill will be critical when you're taking Shooting Positions on Alaska Tundra and Sidehills.
Confirming Zero at Range and with Cold Bore Shot
Once you believe your rifle is zeroed, perform a final confirmation. Shoot at least a three-shot group, ideally at 200 yards, from a cold, clean barrel. The "cold bore shot" is particularly important. The first shot from a cold barrel can sometimes land slightly differently than subsequent shots from a warm barrel. Knowing where your cold bore shot consistently lands is critical, as your first shot in the field will always be from a cold barrel. Many hunters aim for a perfect 1.5-inch high at 100 yards for a 200-yard zero with common cartridges, which helps account for cold bore variations. Document these results, perhaps even taking a picture of your target with your phone.
Post-Arrival Checks and What to Do
You've landed in Alaska, the bush plane has departed, and you're surrounded by the vast wilderness. This is the moment to confirm that all your careful pre-flight preparation hasn't been undone by the journey. Skipping this step is asking for trouble.
Visual Inspection of Your Rifle and Scope
Before you even think about shooting, give your rifle a thorough visual inspection.
- Check the scope: Look for any obvious dents, cracks, or loose components. Are the turrets still tight? Is the objective bell or ocular lens secure? Gently try to twist the scope in its rings – it should be rock solid.
- Check the mounts: Ensure all scope mount screws are tight. Sometimes, minor vibrations can loosen them. A small Torx wrench or screwdriver kit is invaluable for this.
- Check the barrel: Ensure there’s no obstruction in the barrel.
- Check the stock: Look for any cracks, especially around the recoil lug or action screws. A cracked stock can absolutely ruin accuracy.
This quick once-over can often catch obvious issues that might lead to a dramatic shift in point of impact. If anything looks or feels off, it’s better to address it now rather than when you're looking at a brown bear.
The Paper Test: The Absolute Minimum
Even if you can’t get to a full range, you must perform a paper test. This is where a small, portable target or even a piece of cardboard comes in handy.
- Find a safe backstop: This is paramount. Even a .22-caliber bullet can travel over a mile. Ensure you have a clear, safe area, typically a soft dirt bank or a thick tree line, where your bullet will impact harmlessly.
- Set up a target at close range: 25 yards is often sufficient for a preliminary check. If you have enough space and a safe backstop, 50 yards is even better.
- Shoot a three-shot group: Aim precisely at the center. The goal here isn't to be perfectly zeroed for distance yet, but to confirm that your rifle is still hitting where it's looking. If your group is wildly off to one side or vertical stringing is severe, you know you have a problem.
- Adjust if necessary: If your group is consistently off, make small, calculated adjustments to your scope. If you had a 200-yard zero, remember that a 1-inch click at 100 yards is 2 inches at 200 yards, and 1/4 inch at 25 yards. So, for a 25-yard paper test, a 1/4 MOA click will move your point of impact 1/16 of an inch. Make minor corrections and reshoot. This process will at least get you "on paper" at close range.
This simple test is the best way to get a quick confirmation after your flight. If you had any concerns about Scope Damage From Float Plane Vibration, this test would quickly reveal it.
Recalibrating with a Spotting Scope or Binoculars
If your paper test reveals your rifle is off, and you have time and a safe place for a more thorough check, use your spotting scope or high-powered binoculars (like those you might use for Glassing the Alaska Range: Finding Game Before You Move) to help you get dialed back in. Instead of walking downrange after every shot, set up your optics to clearly see your impacts.
- Spotter's role: If you have a hunting partner, have them spot your shots and call out the impact relative to your point of aim. This allows you to stay behind the rifle and make quick adjustments.
- Solo adjustment: If hunting solo, take your shot, safely put your rifle down, and then quickly look through your spotting scope. Note the adjustment needed, return to your rifle, and make the correction.
- Calculated adjustments: Knowing your scope's click values (e.g., 1/4 MOA per click) is vital. For example, if you're shooting at 50 yards and your shots are 2 inches low, and your scope is 1/4 MOA per click, then 1 MOA at 50 yards is 0.5 inches. So, 2 inches low means you need 4 MOA of up adjustment, which would be 16 clicks (4 MOA / 0.25 MOA per click = 16 clicks). Always verify with another shot.
This methodical approach, even if not at a formal range, can save your hunt. Remember, you might be hundreds of miles from the nearest road, and every shot matters.
| Range (yards) | 1/4 MOA Click Value (inches) | 1/2 MOA Click Value (inches) |
|---|---|---|
| 25 | 0.0625 | 0.125 |
| 50 | 0.125 | 0.25 |
| 100 | 0.25 | 0.5 |
| 200 | 0.5 | 1 |
| 300 | 0.75 | 1.5 |
This table illustrates the approximate movement of your point of impact per click for common MOA (Minute of Angle) scopes at various distances. Always refer to your specific scope's manual for exact values.
Essential Gear for Field Verification
Being prepared for a re-zero in the field means having the right tools. You can’t exactly swing by a gun shop in the middle of the Brooks Range. Packing these few items can make all the difference.
Portable Shooting Rest and Bipod
While you might be able to improvise a rest with a backpack or log, a small, portable shooting rest or a bipod attached to your rifle is incredibly helpful for accuracy when making field adjustments. A bipod allows you to quickly get into a stable prone position, which is excellent for zeroing, even if you’re primarily an offhand or treestand hunter. Some backpack hunters even carry a small, lightweight front bag. The goal is to eliminate as much human error as possible from the shooting equation when trying to diagnose an accuracy issue. You'll thank yourself for this foresight when trying to make precise adjustments under pressure, something many overlook when considering their gear loads for a bush flight.
Small Tool Kit for Scope and Rings
A compact tool kit specific to your rifle and scope is non-negotiable. This typically includes:
- Torx wrenches or hex keys: For your scope ring screws and base screws.
- Screwdrivers: Often needed for scope turrets or stock screws.
- Allen wrenches: For many bipod attachments or other rifle accessories.
- A small level: To ensure your scope is mounted perfectly level. While this is primarily for initial mounting, it can also help confirm if your scope has subtly rotated in its rings.
Even if you double-checked everything at home, having these tools lets you tighten a slightly loose screw, re-level a canted scope, or even remove the scope entirely for inspection if you suspect a major issue. Many hunters find resources like GoHunt helpful for researching gear lists from experienced Alaskan hunters, which often emphasize the importance of these small but critical tools.
Known-Good Ammunition and Ballistic Data
As mentioned earlier, always carry extra rounds of the exact ammunition you zeroed with. But beyond that, carry your ballistic data. This can be a small card taped to your rifle stock, a laminated card in your pocket, or data programmed into a ballistic app on your phone (downloaded for offline use, as cell service at remote camps is non-existent). This data should include:
- Your chosen zero distance.
- Bullet drop at various increments (e.g., 50, 100, 150, 200, 250, 300 yards).
- Windage adjustments for a given crosswind at different ranges.
- Your scope's click values (e.g., 1/4 MOA).
Having this readily available will allow you to make precise adjustments for distance, even after your post-flight paper test. It helps bridge the gap between your initial field re-zero and a confident shot at an animal at an unknown range. When you're trying to figure out how to count brow tines on a live bull from afar, knowing your ballistic data for an ethical shot becomes paramount.
Small Targets and Marking Materials
Don't forget to pack a few small, durable targets. Simple paper targets are fine, but even better are small, reactive targets like bright orange stickers or small balloons. Anything that gives a clear point of aim and shows bullet impact clearly. Also, bring a sharpie or pencil to mark your impacts and adjustments. This helps you track your progress and avoid making unnecessary or incorrect adjustments, especially if you’re rushed or frustrated. Remember, the goal is always clear, precise feedback on your rifle’s performance.
Final Thoughts and Peace of Mind
Ultimately, flying into a remote Alaska camp means embracing uncertainty. The weather can change in an instant, plans can go awry, and the wilderness is always ready to throw a curveball. However, your rifle’s zero doesn’t have to be one of those uncertainties. By taking the time to meticulously zero your rifle before you leave, protecting it during travel, and performing diligent checks upon arrival, you’ll eliminate a major source of anxiety and give yourself the best possible chance for a successful and ethical hunt. Remember that building extra days into a fly-in schedule isn't just for weather; it's also for ensuring all your gear, including your rifle, is truly hunt-ready. This attention to detail isn’t just about making the shot; it’s about respecting the animal, the land, and the incredible privilege of hunting in Alaska.
