Unconventional thinking leads to innovation: Meet the next-generation Z Series

Innovation rarely follows the rulebook. At Apex, that’s been our advantage. In our latest Shop Talk, we explored the engineering behind the Z Series and our new Stratified™ concepts. Here’s a slightly different take on that conversation — one that highlights how a contrarian, performance-first decision made our Z waterfowl loads measurably better.

The problem we set out to solve

Steel shot has long carried an unfair reputation: reliable and inexpensive, yes — but often pegged as “entry level” when hunters want the best non-toxic performance. We didn’t accept that binary. Instead, we asked: what if a tiny strategic change to the payload could unlock much better performance without compromising durability or cost?

The reversal: turning a conventional blend on its head

Our ballistic team tried something different: we reversed our traditional WS waterfowl blend approach. Rather than starting with steel and trying to boost it, we began with a TSS-dominant payload and added a pinch of zinc-plated steel. That small, intentional addition flipped performance in a useful way.

What that tiny pinch actually does

By incorporating a small percentage of zinc-plated steel into a predominantly TSS (tungsten super shot) payload, we achieved multiple gains simultaneously:

• Higher stack height with moderate pressure. The payload packs more effectively in the same hull footprint without requiring extreme pressures.
• Improved pattern efficiency. The mixed strata of TSS + steel helps distribute pellets more uniformly through the choke, creating denser, more consistent patterns.
• A lethal buffer replacing PSB polymer. Instead of relying on a polymer buffer (PSB), the zinc-plated steel layer provides tangible mass and energy transfer that improves downrange lethality.
• Increased total payload. We were able to increase total payload to 1¼ oz in 12 ga and 1 oz in 20 ga, with clear performance dividends in pattern density and terminal effect.

The real result: cleaner kills, fewer cripples

Numbers matter, but so do outcomes. In field tests, the Z Series TSS-dominant loads with a steel pinch produced improved pellet dispersion and more lethal patterns across realistic hunting distances. That means better knockdown power, fewer cripples, and a more consistent result—not just on paper but at the blind.

Why this matters to the modern hunter

We don’t chase novelty. We chase measurable advantage. By rethinking the blend from first principles and using an unconventional mix strategy, the Z Series gives hunters a practical step up in performance—especially in scenarios where pattern efficiency and downrange lethality decide the outcome.
