If you’re into big game hunting or just someone who values high-performance ammunition, chances are you’ve heard about Nosler. They’ve been in the ammo game for a long time, and their reputation for quality is well-earned. But today, we’re not just talking about any bullet—they’ve taken one of their legendary designs and added a modern twist. Enter the Nosler Partition Copper.
This bullet takes the time-tested Partition design and gives it a lead-free makeover, making it legal in areas with lead restrictions and appealing to environmentally conscious hunters. But does it still perform at the same level that made the original Partition so iconic? Is it accurate, deadly, and worth the higher price tag?
In this review, we’ll break it all down in a no-nonsense, easy-to-digest format. Whether you’re considering the Partition Copper for an upcoming elk hunt or just want to know how it stacks up against other premium hunting rounds, we’ve got you covered.
Nosler Partition Copper: Specs and Performance Breakdown
Before we dive into hands-on impressions and field performance, let’s take a look at the specs and key features that define the Nosler Partition Copper bullet. Here’s a breakdown to get us started:
| Feature | Details |
| Bullet Type | Lead-free, all-copper expanding bullet |
| Design | Dual-core (Partition design) with front expansion cavity |
| Available Calibers | .30-06 Springfield, .308 Winchester, .300 Win Mag, and others |
| Bullet Weights | Typically 150, 165, and 180 grains (varies by caliber) |
| Ballistic Coefficient (BC) | Moderate, typically around .400 depending on weight and caliber |
| Muzzle Velocity | Varies by load and barrel length, but usually 2,800 – 3,000 fps |
| Intended Use | Big game hunting, including deer, elk, moose, and bear |
| Legal Use | California-compliant (lead-free) |
At first glance, it’s clear Nosler was aiming for something that would retain the classic reliability of the Partition design while meeting modern hunting regulations. The all-copper construction is a key change, but they’ve kept the dual-core partition feature that made the original a trusted choice for decades.
What Makes the Nosler Partition Copper Stand Out?
When it comes to premium hunting bullets, the competition is fierce. So what gives the Nosler Partition Copper its edge? Here are some key qualities that really shine in the field:
Proven Partition Design in Copper Form
The original Nosler Partition has been a go-to for hunters for over 70 years. This copper version retains that dual-core concept, which means the front of the bullet is designed to expand rapidly, while the rear stays intact for deep penetration. That’s a big deal when you’re trying to bring down something big like an elk or bear.
Lead-Free Hunting
With lead-based ammunition being banned in more areas—California being the most prominent example—the Partition Copper gives hunters a legal and ethical option without sacrificing terminal performance. It’s also safer for scavengers and the environment.
Reliable Expansion and Weight Retention
Copper bullets can sometimes suffer from inconsistent expansion, but Nosler seems to have cracked the code here. The Partition Copper expands consistently even at lower velocities and holds its weight very well. That’s important if you’re taking longer shots or hitting heavy bone.
Deep Penetration for Large Game
The dual-core design isn’t just marketing fluff. In real-world hunting situations, this bullet consistently penetrates deeply, even on tough animals. Hunters have reported full pass-throughs on broadside elk and excellent blood trails.
Accuracy That’s Good Enough
Let’s be honest—there are more accurate bullets out there if you’re punching paper. But this isn’t a target round. The Partition Copper offers hunting-level accuracy, which means consistent 1.5 MOA or better in most rifles. That’s more than enough for ethical shots at typical hunting ranges.
FAQs
Is the Nosler Partition Copper good for elk hunting?
Yes, it’s excellent for elk. Its deep penetration and controlled expansion are perfect for thick-skinned and heavy-boned animals like elk. Many hunters trust it for that exact purpose.
How does it compare to the original Nosler Partition?
The performance is similar in terms of expansion and penetration, but the Copper version is completely lead-free. It may have a slightly different point of impact and ballistic coefficient, but the core hunting performance remains very close.
Is it legal in all 50 states?
It’s legal in all states that allow lead-free ammunition. In fact, it’s one of the better options if you’re hunting in a lead-restricted area. Always check your local regulations before heading out, though.
What kind of accuracy can I expect?
Most hunters see 1 to 1.5 MOA accuracy with properly matched rifles. Some report even better, but it really depends on your rifle and how well it likes the load.
Does the copper construction cause barrel fouling?
All-copper bullets can cause more fouling than traditional lead-core rounds, but Nosler’s design minimizes this issue. Cleaning every 20-30 rounds usually keeps things running smoothly.
Are they worth the price?
That depends on your priorities. If you want a lead-free round that performs like a classic Partition, then yes—they’re worth the cost. They’re not cheap, but quality never is.
Conclusion
At the end of the day, the Nosler Partition Copper is built for hunters who need serious performance from a lead-free bullet. It blends modern environmental considerations with the proven performance of Nosler’s original Partition design.
While it may not be the absolute best choice for tiny groups on paper targets, that’s not what it was made for. This is a bullet designed to bring home game, even in tough conditions, and it does that job extremely well.
If you hunt in areas with lead restrictions—or just want to make a more environmentally friendly choice without compromising on terminal performance—the Nosler Partition Copper is a solid investment. It’s accurate enough, tough enough, and smartly designed to get the job done.
