Best Ammo for Deer Hunting, Tested for Accuracy

Every major ammunition company has a specific product line dedicated to whitetail hunters. Ideally, this ammo will provide good accuracy, function reliably, be widely available, and deliver consistent terminal performance – all at a wallet-friendly price.

I tested six popular whitetail loads to compare their precision at the bench, how they fed and cycled, and the consistency of their velocities in an effort to determine which shot best and whether any should be avoided. This video shows all the results in real time and gives details on their relative performance.

All the loads were chambered in 6.5 Creedmoor. I chose the 6.5 Creed because it is today’s most popular big-game centerfire rifle cartridge; it is stocked everywhere from Alabama to Alaska; and, as the poster child of Modern Cartridge Design, it is inherently accurate and I wanted the ammo in this test to perform as well as possible.

Test Protocol

I put each load through two different rifles. One is the Seekins SIC Short Action, a high-end precision rifle that I’ve been using extensively for the last year and is slated to be released to the public in 2027. The other is a Ruger American Rifle Gen II, one of the best all-around hunting rifles for those on a budget. We’ve been big fans of the Ruger American since it was introduced – it won an Editor’s Choice in our annual gun test when it debuted – and the platform continues to impress us with its combination of accuracy-enhancing features, good stock ergonomics, and smooth-cycling action.

I put 20 rounds of each whitetail ammo through each rifle for a total of 40 rounds per offering. I measured those 5-shot groups on my E.A.T.S. targets to come up with an average group size by rifle and then calculated the combined average group size of all eight groups through both rifles.

I captured velocity data on a Garmin Xero C2 Chronograph. The Garmin’s ability to stop and restart sessions allowed me to gather 20 shots of data with each gun and ammo combo for the velocity averages, extreme spreads (ES), and standard deviations (SD). With factory ammo, any 20-shot SD in the teens is very good and there’s nothing wrong with values in the 20s either, especially for the center-of-mass deer hunting ammo we’re showcasing here.

The Best Whitetail Ammo

The results of the test were fascinating. The Winchester Deer Season XP and Barnes Harvest performed extremely well, Federal’s Fusion Tipped delivered very good precision, the Nosler Whitetail Country and Hornady American Whitetail loads were solid all around, and the Remington Core-Lokt Tipped gave mixed results that serve as a cautionary tale when selecting hunting ammo.

Whitetail Ammo Precision and Velocity Data

This data is based on the average of four 5-shot groups with each rifle and ammo combination. The combined value is the average of how the ammunition did in both the Seekins SIC SA and the Ruger American Rifle Gen II.

The muzzle velocity and standard deviation data is also based on 20 shots, except for the Federal 140-grain Fusion Tipped, which is based on 30 shots of data.

Best Whitetail Ammo

Buy It At Midway USA Buy It At Bass Pro

This is the most visually distinctive ammo in the test with Winchester’s oversized polymer tip that’s designed to produce violent and quick bullet upset upon impact.

This ammunition delivered the best groups overall, with a 5-shot average of .700 inches. The 20 shots through the Seekins averaged .652 inches, while the Ruger’s groups averaged .749 inches.

You can find it online for about $35 for a box of 20, but it is currently hard to find a vendor that has it in stock. The 125-grain version is available but wasn’t the load we tested so we can’t assume it will perform at the same level.

The Harvest Collection is the love child that resulted from the union of Barnes Bullets and Sierra Bullets, which were joined in corporate matrimony back in 2020. I’ve had excellent results with this ammunition, which was officially unveiled in April 2025, both in terms of its accuracy at the bench and its performance in the field.

The idea behind the Harvest Collection is simple. Barnes took Sierra’s well-regarded Tipped Game King bullet and loaded it in their brass on their machinery, which has a reputation for holding tight tolerances.

With an overall average 5-shot group size of .704 inches, it finished just behind Winchester in this evaluation. That said, I’ve had even better results with this ammunition in other rifles, such as my Sako TRG 22-A1. My groups through that rifle averaged .491 inches at 2692 fps with a 15.7 fps SD.

I’ve used this load on a few whitetails at this point, and the terminal results have been excellent too.

You can find the 6.5 Creedmoor load online for about $40 per box of 20.

Federal 140-grain Fusion Tipped

The Fusion Tipped bullet has become a go-to of mine in the last couple of years not only for whitetails, but also antelope, elk and mule deer.

In terms of its construction, it falls between traditional cup-and-core projectiles and true bonded bullets with respect to its toughness. It’ll retain weight better than a non-bonded bullet but is cheaper to produce than a chemically bonded bullet and has the added benefit of being more inherently accurate than one, too.

In truth, the Fusion Tipped strikes a beautiful balance between accuracy, terminal performance, and economy. During this test the 140-grain Fusion Tipped averaged .989 inches in group size, with the Seekins turning in .784-inch groups and the Ruger delivering 1.194-inch groups.

I’ve found the 6.5 Creedmoor online for $46 to $50 per box, which makes it one of the more expensive whitetail-oriented ammo offerings. If that’s a bit rich for your blood, consider the traditional Fusion line, which can usually be found for a few dollars less per box.

Nosler 140-grain Solid Base Whitetail Country

The Nosler Solid Base bullet was first introduced more than half a century ago, but it never caught on like the company’s iconic Partition and Ballistic Tipped projectiles and there were years where the company halted production altogether.

But this cup-and-core soft point, with its tapered jacket, makes for a dandy hunting bullet for whitetails and other big game at moderate distances and it is enjoying a revival of sorts in Nosler’s Whitetail Country lineup.

The bullet’s accuracy in this test was solid. With 5-shot groups averaging 1.167 inches it is more than capable of taking deer at distances to 300 yards or more. Interestingly, this ammunition was the only one in the test where the budget-oriented Ruger American Rifle outshot my fancy-pants Seekins SIC. My four 5-shot groups from the Ruger averaged 1.131 inches, besting the Seekins which averaged 1.202 inches.

The 140-grain 6.5 Creed load goes for $33 to $40 per box of 20 online, making it one of the more affordable selections in the test.

Inside the jacket of this bullet is a raised ring that helps keep the lead core in place as it expands and penetrates within the target. That “locking” element gave the InterLock its name and it’s been part of the American hunting landscape for half a century now.

Loaded in the American Whitetail line, it is one of the most affordable bread-and-butter offerings for big-game hunters. The price per box hovers around $33 currently.

Its attractive price tag and its reasonable performance — through the two test rifles its average 5-shot group average measured 1.375 inches — earned it a Great Buy award in this round up.

Remington 129-grain Core-Lokt Tipped

This ammunition delivered the largest overall groups in the test, with a 5-shot average of 1.519 inches. On the surface, that’s mediocre performance, but it comes with a significant caveat.

The Ruger American Rifle Gen II did not care for this ammunition. The four 5-shot groups measured 2.065, 2.699, 2.392, and 2.143 inches, for an average of 2.325 inches. That isn’t a result I’d feel confident hunting with, and I doubt many of you would be satisfied with it either.

But through the Seekins SIC SA, the ammo hammered. Those four groups came in at 1.039, .595, .589, and .630 inches, averaging .713 inches overall. Across the 12 rifle and ammo combinations in the test that was third only to how well the Seekins shot the Barnes Harvest ammo at .642 inches and Winchester ammo at .652 inches.

The lessons here are that there’s no reason for you to go afield with substandard precision from a modern hunting rifle shooting quality modern ammunition, and that it pays to test out different loads when preparing for firearms season.

The Core-Lokt Tipped offering in 6.5 Creed runs around $43 online currently.

Final Thoughts on the Best Whitetail Ammunition

Investing in a few boxes of ammunition is all it takes to help your deer rifle reach its precision potential. Four 5-shot groups will yield more reliable data than three, but even 15 well-placed deliberate shots on target will give you a good feel for the performance of your system.

In any event, there’s no reason to head to your favorite stand or block of public ground with a nagging sense of uncertainty about how your rifle will shoot when that big buck steps into the clear.

As you can see from this evaluation, even with a budget-minded rig like the Ruger, you can have a true sub-MOA rifle if you take the time to figure out what your hunting rig likes.
