GECO ZERO in Practice: 7 Questions Hunters Ask Before Switching to Lead-Free Ammunition

Hunting lead-free – but which bullet should you choose? Anyone considering a switch to lead-free hunting ammunition is likely to have a few questions: 

How does the bullet perform on impact? 

Which game species is it suitable for? 

And what does switching ammunition mean for your rifle? 

We take a closer look at GECO ZERO and answer seven common questions that matter to hunters in the field.

Switching to Lead-Free Ammunition – What Really Matters?

Whether driven by legal requirements, hunting ground regulations or personal preference, lead-free hunting ammunition has become an important consideration for many hunters. But those who have traditionally relied on lead-core bullets usually have one key question before making the switch: Can I trust lead-free ammunition to deliver the same reliable performance?

The good news is that modern lead-free bullets offer different solutions for a wide range of hunting requirements. The key is finding the right bullet for your particular hunting needs.

With GECO ZERO, GECO offers a lead-free, partially fragmenting bullet designed for rapid energy transfer and high knock-down effect. So, what makes it different, and what should hunters consider when switching? 

Here are the answers to seven frequently asked questions.

1. What Makes GECO ZERO Special?

Two tin cores, two distinct functions – one cleverly engineered bullet design.

GECO ZERO combines rapid energy transfer with a mass-stable residual bullet body. While the front section is designed to expand and fragment rapidly on impact, delivering a high knock-down effect, the rear section provides the penetration needed for reliable terminal performance.

The result is a lead-free hunting bullet suitable for a wide range of native game species, particularly in situations where rapid bullet performance and energy transfer are essential.

2. Which Game Species Is GECO ZERO Suitable For?

From foxes and roe deer to young wild boar, GECO ZERO is a versatile hunting bullet.

Its strengths are particularly evident when hunting light to medium-sized game. Although it is generally designed for all native game species, the suitability of a particular load also depends on the calibre used and the specific hunting situation.

After all, the same principle applies to lead-free ammunition: Not every calibre is suitable for every hunting application.

3. How Does the Dual Tin-Core System of the GECO ZERO Work?

At the heart of GECO ZERO's design are its two tin cores, each with a clearly defined function.

The front core features predetermined breaking points that allow it to fragment in a controlled manner on impact, transferring energy rapidly to the target. The rear tin core, together with the bullet base, forms a mass-stable residual body that ensures the necessary penetration.

In short: rapid energy transfer at the front, reliable penetration at the rear. This combination is what makes the terminal performance of GECO ZERO unique.

4. What Is the Difference Between the two leadfree bullets GECO ZERO and GECO STAR?

Both bullets are lead-free, but they are based on different design principles.

GECO ZERO is a partially fragmenting bullet with two tin cores. Its main focus is rapid energy transfer and a high knock-down effect.

GECO STAR, on the other hand, is a monolithic copper expanding bullet. It expands in a controlled manner and is designed to retain a high percentage of its original weight while delivering deep penetration.

Which bullet is the better choice depends on the game species, calibre and individual hunting requirements. 

After all, not all lead-free bullets are created equal.

5. Do I Need to Clean My Rifle Barrel Thoroughly Before Switching to GECO ZERO?

The short answer: Generally, no.

Thanks to its tombac-plated steel jacket, GECO ZERO behaves similarly to conventional jacketed bullets in terms of barrel fouling. Extensive chemical cleaning is therefore not normally necessary when switching ammunition.

Regular barrel maintenance is generally sufficient. However, it is important to test the new load at the shooting range before taking it into the field. Even when using the same calibre, the point of impact may differ from that of your previous ammunition.

6. Which Calibres Is GECO ZERO Available In?

GECO ZERO is available in a wide range of popular hunting calibres, including:

.308 Win.

.30-06 Springfield

.300 Win. Mag.

7x64

8x57 JS

9.3x62

This selection covers many common hunting applications, from everyday hunting in your local grounds to a variety of high-seat hunting and stalking situations.

7. Why Should I Choose GECO ZERO?

Because switching to lead-free ammunition does not mean compromising on proven hunting performance.

GECO ZERO combines high accuracy with a distinctive terminal performance concept: The front tin core ensures rapid energy transfer, while the rear core forms a stable residual body for reliable penetration.

This makes it an attractive alternative, particularly for hunters who primarily pursue light to medium-sized game and value rapid bullet performance on impact.

Conclusion: Making the Switch to Lead-Free Ammunition with the Right Bullet

When switching to lead-free hunting ammunition, the decision should involve more than simply choosing between lead and lead-free. What matters far more is how a bullet is constructed, how it performs on impact and whether it suits your hunting grounds and preferred game species.

With its dual tin-core system, GECO ZERO offers a distinctive solution: rapid energy transfer, a high knock-down effect and a mass-stable residual body for reliable penetration.

Our tip: Test your chosen load at the shooting range, check the point of impact and familiarise yourself with the bullet's performance characteristics. Once you've done that, you're well prepared to make the switch to lead-free hunting ammunition.
