Winchester Supreme Long Range Review: A New Standard for Deer Hunters

The Winchester Supreme Long Range is built to perform at any distance, from 50 yards to 500.

This isn't just another line of deer ammunition. These bullets aim to meticulously balance accuracy with impact.

I had no doubts Winchester made a quality cartridge, but could it really be so much different from the excellent ammo they already produce?

After testing the much-hyped Winchester Supreme Long Range out in the field and on the range, here is what you need to know before you buy.

Winchester Supreme Long Range First Impressions

Typically, a whitetail deer kicks out its hind legs when shot, letting you know you were successful. This time was different, very different, and I can only chalk it up to the Supreme Long Range ammunition.

“Are you sure you hit him?” asked my host, Will Brantley, as we stood over what looked like the beginning of a short blood trail.

“Oh yeah, he can’t be far.”

“Did he buck?”

“No, but it was pretty obvious by the way he staggered away.”

Instead of the typical kick, I saw an impact ripple down the length of the deer’s body as he stumbled away, cresting jagged terrain shortly beyond where he had stood. Pulling my thermal monocular from my pack, I scanned the ravine and began to smile.

“There he is!” I exclaimed as Will and I finally got eyes on him. With nothing left in the tank, he had rolled more than 250 yards to the bottom of a dry creek bed.

“Dead as can be,” Will sighed in relief, as we noted the well-placed double-lung shot.

It was a first for me, as I’ve never watched a deer take a hit and stumble away like a cowboy in a 1950s western. It was also my first experience with Winchester Supreme Long Range ammunition.

Winchester Arrives Late to the Long-Range Game

While my story with the new ammo began just five days before this harvest, Winchester’s began several years earlier.

It’s no secret the shooting industry was missing a long-range hunting load from this manufacturer, as most of its competitors already had at least one.

One reason Winchester delayed was that other projects took precedence, such as supplying the nation’s war fighters and lawmen.

However, they also had a lack of capacity. Making a projectile that performs as well at close range as at it does at distance requires specialized equipment.

The BC Max Bullet is the Heart of Winchester Supreme Long Range

Winchester is vocal about their investment for this project, but they're keeping the specifics very close to their chest. To be honest, the details don’t matter to those of us sending it across a prairie.

Any long-range bullet has to cut through air better than traditional ammunition, which means Supreme Long Range had to start with a strong ballistic coefficient. Right on queue, Winchester dubbed their new bullet the BC Max projectile.

This component took the lion’s share of Winchester’s engineering muscle. Making a bullet that flies straight and is lethal at a wide impact velocity band isn’t terribly difficult.

But when you want to extend that band nearly indefinitely, a suite of design features must co-exist, and that takes the right combination of man and machine.

How Winchester Supreme Bullet Jackets Impact Performance

Beginning with the jacket, Winchester's new tooling was able to draw these differently than the company’s legacy bullets.

Vitals get very small beyond 400 yards, so the projectile must spin true for flawless stability and accuracy. This begins on the outside with this critical subcomponent.

If a jacket is even marginally thicker (heavier) on one side, the bullet will not remain balanced in flight, leading to erratic impacts and making every other effort moot.

BC Max jackets are thicker than previous Winchester jackets, limiting fragmentation on high-speed impacts. From there, the primary exterior characteristics take shape, and that means extended boattails and a sleek profile.

Once the initial copper shell was complete, Winchester filled it with a specific alloy to achieve the desired weight and rigidity. Too hard, and the bullet will fracture like a piece of glass. Too soft, and it will expand too fast or possibly deform mid-flight.

Winchester turned to the age-old solution of using high-antimony lead. The engineers were able to tune the core to perform at both ends of the spectrum.

The high-antimony lead flows around a stake formed at the back of the jacket, mechanically locking the two parts together.

Lastly, the oversized, heat-resistant polymer tip breaks away instantly upon impact. As this is the widest tip in its class, it leaves an expanded frontal diameter, making it hit like a flat-point, despite flying akin to a needle-like target bullet.

Supreme Long Range Powders Are Proven Performers

Ammunition is only as strong as the weakest link in the chain, so even a perfect bullet needs the right push behind it to produce accurate, consistent results.

The good news is Winchester has already paired its initial Supreme Long Range offerings with the right powders for each bullet weight.

The load I hunted with, and later tested at home, was the 140-grain 6.5 Creedmoor. Only a few propellants work well in this application, and some were developed specifically for this cartridge, which made the team’s job easier.

I pulled a sample and saw that Winchester had chosen a ball powder, which pleased me. While I can only speculate about which one the company used, ball powders always dispense more uniformly than extruded rod or stick powders.

To that end, my loads were within .05 grains of one other. This level of consistency rivals handloads built by weighing each charge on a scientific scale.

Supreme Long Range Cartridge Looks Good and Performs Better

While good bullets and powder are essential for accuracy, long-range predictability requires uniform velocities from shot to shot. If bullets leave the muzzle at different speeds, they will impact in a vertical string.

If the spread is great enough, or the distance far enough, that could mean the difference between a shot in the vitals or one in the back, or even a miss.

Starting with ignition, you need the same amount of powder to light each time. That allows the entire charge to burn up at the same rate and build uniform pressure with each trigger press.

For this, Winchester turned to its match-grade primers, which they typically reserve for products built to cut X-rings. For Supreme Long Range, they select match-grade primers from the masses based on how well they meet the design's weight, concentricity, and other specifications. This ensures uniformity.

Once a cartridge is burning uniformly, the bullet must be exit the case identically from shot to shot, and box to box. This requires neck tension consistency, which also needed an overhaul.

Winchester revolutionized their case drawing methods for Supreme Long Range, resulting in greater uniformity than ever before.

They finish the final product with a luxurious nickel plating that helps the cartridges resist corrosion while aiding low-light manipulation during dusk and dawn. Nickel also has a natural lubricity that helps them feed through magazines, which becomes important for autoloaders, or even fast work with a bolt action.

How Did Winchester Supreme Long Range Perform in the Field?

Unlike most ammo stories I write, the test protocol for this one was entirely backwards. Typically, I spend some time with a cartridge before I take it on a hunt. Here, they handed me a rifle, I took one shot to confirm my zero, and then took my next shot at a deer.

Performing something between fine butchering and an episode of CSI, the bullet recovery told me that I wanted to know more. Many studies have focused on animals taken beyond 300 yards with this family of bullets, but my deer was one of the few taken at typical Eastern hunting distances.

With my deer standing just 50 yards from the muzzle, I got to see the performance on the near side of the spectrum, and I was pleased. The bullet fragmented a little, but that is to be expected that close, and the carnage inside was straight out of a horror movie.

Supreme Long Range Dominated the Tests

Once I got home, I requested half a case of the same 6.5 Creedmoor load I was using, as well as similar products from Winchester and its sister company, Browning. My goal was to put ammunition made with the new processes up against that made with conventional methods.

I also decided to use the same gun I used on the hunt, a Winchester Model 70 Extreme TrueTimber VSX MB.

A spin on the classic, it features a weatherproof metal finish and a TrueTimber Strata Bell and Carlson stock, which, if I could be a hunting diva for a moment, matched my cold-weather getup.

I topped it off with one of Winchester’s new 3.5-10x Supreme scopes and was reunited with an old friend.

Alternating five-shot groups of each type, the Winchester Supreme Long Range was proving to be quite the performer.

It was a fair bit faster than the other 140-grain loads with a lower standard deviation and lower extreme spread. This second part of that statement proves Winchester’s refinement work in numbers, telling us that what they say is indeed more than a marketing ploy.

What About Supreme Long Range's Ballistic Coefficient?

With both the average and smallest groups coming out on top, I thought it was about time to test the “BC” part of the BC Max bullet.

Our club has two-MOA steel all the way out to 1,000 yards. Most regard a whitetail’s vital area somewhere between 8 and 10 inches, which means that both the 400- and 500-yard targets are a fair representation of a long-range shot on a deer.

With a 5-8 MPH wind blowing across the range, I favored less than half a plate into it and hammered both targets five times each, using the same dope from my 6.5 Creedmoor match load.

My decision to push into the wind came from my long-range shooting experience. Even without the hold, you’d still be looking at a good vital hit at either of those distances.

Winchester Supreme Long Range a Winner

My experiences both in the field and at the range made it obvious that Winchester poured their heart and soul into this ammo family.

It is currently available in a wide variety of cartridges, ranging from ultra-modern to deer-camp classics. Four more are on the way, making it almost a guarantee that you have a rifle chambered for it somewhere in your safe.

Either long or short, the Winchester Long Range Supreme is devastating on game, and the only distance you’ll ever have to think about again is how far a drive it is to your camp.
