ALCO Bullet Talk #8
Know Your Zero. Know Your Rifle. Know Your Bullet.
Build Confidence Before the Hunt.
Every successful shot begins long before the trigger is pulled.
Airgun hunting demands more than knowing where your rifle is zeroed. Confidence in the field comes from understanding how your air rifle, bullet, air pressure, and point of impact work together at the distances you may encounter during a hunt.Whether you’re preparing for hunting season or competing on the range, confidence isn’t built by luck—it’s earned through practice, understanding your equipment, and knowing exactly how your rifle performs.
A bullet that is perfectly zeroed at 50 yards won’t strike the same point of impact at 75 or 100 yards. As distance increases, trajectory changes, gravity has more time to act on the projectile, and even small changes in velocity caused by decreasing reservoir pressure become more noticeable. Learning how your rifle and bullet perform together at multiple distances is knowledge you simply can’t gain from a single group at one range.
The technique that follows takes less than an afternoon at the range, yet it can teach you more about your rifle than months of casual shooting. Whether you’re building confidence for competition or preparing for an ethical hunt, understanding your rifle’s complete shot string, trajectory, and point of impact gives you confidence that no amount of guesswork ever will.
Learn Your Rifle—One Distance at a Time
50 Yards — Establish Your Zero
Begin with a full air reservoir and zero your rifle at 50 yards using the slug or bullet you plan to hunt. Zeroing your rifle at 50 yards is only the beginning. The real lesson comes as you move farther downrange. Hunting will require that you understand how bullet trajectory changes over multiple shots when the air supply is being consumed.
Instead of firing one or two confirmation shots, shoot an entire string.
For many PCP rifles, that may be three, four, five, or even more shots depending on the rifle, power setting, and usable pressure range.
Now watch what happens.
As reservoir pressure decreases, velocity begins to change. Many rifles eventually move beyond their ideal operating pressure, and the point of impact starts to shift. Some rifles change very little, while others show a noticeable difference.
Every rifle has its own personality.
The only way to truly know yours is to shoot it.
Record Everything
Don’t rely on memory.
Write down:
- Air reservoir pressure
- Shot number
- Distance
- Point of impact
- Wind conditions
- Slug or bullet used
These simple notes quickly become one of the most valuable tools you own. Weeks or even months later, you’ll still know exactly how your rifle performed instead of relying on memory.
75 Yards — Watch the Trajectory Develop
Move the target to 75 yards, then 100 yards, and repeat the same process. As the distance increases, you’ll watch the bullet’s trajectory drop. What looked like a perfectly consistent rifle at 50 yards may begin to show changes in point of impact as velocity decreases through the shot string. Learning where they occur gives you the confidence to know exactly where your bullet will land when the shot matters most and you are using a tank that is not a maximum pressure.
Don’t fire a single group and stop.
Shoot another complete string through the rifle’s usable pressure range.
Pay close attention to how your point of impact changes.
Many shooters are surprised by how little—or how much—the difference can be.
100 Yards — Build Confidence Before the Hunt
By the time you move back to 100 yards, the lesson becomes much clearer. Gravity and velocity have more time to act on the bullet, and the trajectory begins to drop more noticeably. That’s why understanding your rifle at multiple distances is so important.
This is where the information becomes truly valuable.
Small changes in velocity that were barely noticeable at 50 yards become much more apparent at 100.
By the time you’ve repeated this process at 50, 75, and 100 yards, you’ll have something far more valuable than guesses—you’ll have confidence built on proven results.
Know the Distance
When you’re hunting, judging distance by eye can be surprisingly difficult—especially across an open field, through timber, or on uneven ground. Consider carrying an inexpensive laser rangefinder. Even basic models, including many originally marketed for golf, can give you a quick distance reading and remove much of the guesswork. Knowing whether an animal is 55 yards away or 85 yards away matters when you already know how your rifle and bullet perform at those distances. A rangefinder doesn’t replace practice; it simply helps you apply what you learned at the range when you’re in the field. The goal isn’t to encourage a longer shot—it’s to give you better information to decide whether the shot is one you should take at all.
Keep Your Data Close
Once you’ve collected your information, organize it into a simple reference chart.
Many hunters keep those notes on a waterproof card attached to the rifle, inside a buttstock pouch, or tucked into a cartridge holder. This is a DOPE card (Data On Previous Engagements), using recorded holdovers and elevation adjustments for different distances.
Whatever you call it, the purpose is the same.
When the moment arrives, your information is already there. You won’t be guessing where to hold or trying to remember what your rifle did the last time you practiced.
Where you hunt also matters. If you’re hunting in thick timber or dense brush, most shots may be well under 50 yards. In more open country—prairies, fields, powerline cuts, or western landscapes—you may encounter opportunities at considerably longer distances. Knowing exactly how your rifle and bullet perform at 50, 75, and 100 yards allows you to make informed decisions in the field rather than guessing when the moment arrives.
Ethical hunting begins with preparation. Every hunter has a responsibility to know the effective range of both their equipment and their own abilities. Confidence isn’t about stretching the distance—it’s about understanding your trajectory, knowing your holdover, and taking only the shots you’ve proven you can make consistently and accurately.
Confidence comes from preparation—not memory.
That confidence also leads to more ethical hunting.
Your maximum range isn’t determined by your rifle—it’s determined by the farthest distance at which you’ve proven you can consistently place a precise shot. Understanding your trajectory, practicing at realistic distances, and knowing your rifle’s limits all contribute to quick, humane harvests.
Of course, understanding your rifle is only part of the equation.
The projectile matters just as much.
Every ALCO bullet is engineered around three performance goals: uncompromising accuracy, superior ballistic efficiency in flight, and dependable terminal ballistics on impact.
Accuracy always comes first. A projectile must reach its intended point of impact before anything else matters. From there, ballistic efficiency helps retain velocity, reduce wind drift, and maintain predictable flight as distances increase.
Finally, terminal ballistics determine what happens after impact.
Whether it’s one of our precision rifle bullets or an ALCO airgun slug, each projectile is engineered to perform throughout the entire shot. Aerodynamic design promotes efficient flight, while hunting designs are engineered to deliver dependable terminal performance when they reach the target. The result is confidence that extends from the muzzle to the moment the shot is complete.
Learning your rifle takes time, but it’s one of the best investments any shooter can make.
Confidence isn’t built on assumptions.
It’s built on practice, recorded results, and equipment you trust.
Because when the moment of truth arrives, confidence before the hunt becomes confidence behind the trigger.
