An Outdoor Life report published Oct. 30, 2026, compared 6.5 Creedmoor and .300 Winchester Magnum factory loads in ballistic gel at 200 yards. The .300 Win. Mag. struck faster and with more energy, while the reported penetration and wound-cavity diameter were nearly identical in this test; the results do not establish that the cartridges are interchangeable in hunting.
Outdoor Life published a comparison of 6.5 Creedmoor and .300 Winchester Magnum loads, testing their performance in ballistic gel at 200 yards. The .300 Win. Mag. bullet arrived faster and carried more energy, but the test recorded nearly identical penetration and wound-cavity diameter—a result that complicates the idea that a larger magnum automatically provides a much wider margin for error on a hunting shot.
In the report, Outdoor Life writer Tyler Freel fired Federal Fusion Tipped factory ammunition into identical Clear Ballistics gel blocks. The setup placed the targets at 200 yards, with a chronograph about 15 yards in front of them to record impact velocity. Freel said the gel provides a consistent medium for side-by-side comparison but is not a one-to-one representation of animal tissue.
The 6.5 Creedmoor load used a 140-grain bullet and recorded an impact velocity of 2,233 feet per second. The .300 Win. Mag. used a 180-grain bullet and recorded 2,526 feet per second. The report listed expanded diameters of 0.446 and 0.554 inches, respectively; penetration was 20.75 inches for the 6.5 Creedmoor and 20 inches for the magnum. Both produced a reported 2.25-inch wound-cavity diameter.
Freel described the .300 Win. Mag. as delivering more energy and visibly striking the gel harder. But he reported that the wound channels and penetration were close in this particular test. He cautioned that the comparison does not mean the cartridges are completely equal: the test involved one ammunition type per cartridge, specific rifles and barrel lengths, and gel rather than a harvested animal.
What the Gel Test Can Show
The comparison speaks to a common hunting choice: a milder cartridge that many shooters find easier to practice with, or a magnum cartridge offering higher velocity and energy. Outdoor Life presents the test as a check on the assumption that the extra power will necessarily produce a dramatically larger wound and compensate for an imperfect shot.
For readers choosing a hunting rifle, the measured results highlight that energy figures alone do not describe every terminal-performance outcome. Bullet design, impact conditions and shot placement also matter. The report’s findings may inform a cartridge comparison, but they do not establish that either round is suitable for every animal, range or angle, or that a hunter can safely rely on extra power to make up for poor placement.
The practical choice also involves the shooter. Freel argues that recoil and the ability to practice comfortably are relevant considerations. That is his assessment, not a universal measurement from the gel test. The report does not quantify recoil, shooter accuracy or hunting outcomes for either cartridge.

How the Two Loads Were Compared
The source report describes two broad approaches among hunters. Supporters of smaller cartridges point to their lower recoil and the ability to shoot them comfortably and practice often. Supporters of magnums emphasize higher velocity, larger bullets and more energy, particularly for larger game or longer shots. These are competing considerations rather than a finding that one cartridge is best for every hunter.
For its comparison, Outdoor Life used rifles that were the same except for barrel length: 18 inches for the 6.5 Creedmoor and 22 inches for the .300 Win. Mag. It used one 140-grain and one 180-grain Federal Fusion Tipped load. Since cartridge, bullet weight and barrel length differed, the test is a comparison of those specific rifle-and-ammunition setups—not a controlled test isolating cartridge alone.
The report notes that the .300 Win. Mag. is used for big game, including moose, and can be used at extended distances. It does not provide a broad field trial or compare results across multiple bullet brands, game species or shot angles. The gel demonstration is therefore a limited data point, not a complete hunting-performance ranking.
“This gel isn’t a one-to-one representation of flesh, but it is a homogeneous, consistent medium in which we can get a side-by-side comparison of two bullets.”
— Tyler Freel, Outdoor Life
Limits of the Test Results
The report describes a single comparison using one load for each cartridge and gel targets at one distance. It does not establish how other bullet designs would expand, penetrate or damage tissue, or how either load would perform on different animal species, shot angles or impact conditions. Gel is a consistent test medium, but it is not animal tissue.
The comparison also used different barrel lengths and bullet weights, so the measured differences cannot be attributed to cartridge alone. The report does not provide a sample size across repeated shots in the supplied material, nor does it present field results or a statistical analysis. Its findings support a narrow conclusion about the tested loads and setup, not a definitive claim that one cartridge offers no advantage or that the other provides a guaranteed safety margin.
Freel’s supplied report excerpt ends before listing all of its takeaways. Further conclusions from the original article are not detailed here.
What Hunters Should Compare
The report offers no announced follow-up test or new field data. For readers weighing the cartridges, the next useful step is to compare the exact ammunition intended for use, including bullet construction and published performance information, and to check that it is appropriate for the intended game and local rules. The gel result alone cannot settle that choice.
Hunters should also account for their ability to shoot a rifle accurately and practice with it. The Outdoor Life report favors considering shootability alongside power, but individual recoil tolerance and rifle fit vary. A qualified firearms instructor or experienced hunting professional can help assess safe handling, marksmanship and equipment choices. Whatever the cartridge, the report does not support treating greater energy as a substitute for responsible shot selection and placement.
Key Questions
Which cartridge had the higher impact velocity in the test?
The .300 Win. Mag. load recorded 2,526 feet per second at the target, compared with 2,233 feet per second for the 6.5 Creedmoor load.
Did the .300 Win. Mag. penetrate farther in the gel?
No. The report listed 20 inches of penetration for the .300 Win. Mag. and 20.75 inches for the 6.5 Creedmoor in this test.
Did the two loads make the same wound cavity?
The report gave both loads a 2.25-inch wound-cavity diameter. It also noted that the .30-caliber bullet disrupted slightly more tissue across its path, while describing the overall channels as nearly identical.
Does the test prove the cartridges perform equally on game?
No. The comparison used ballistic gel, which the report says is not a direct representation of flesh, and tested just one load per cartridge in a particular setup. It does not establish equal performance across animals, bullets or field conditions.
What factors should a hunter consider besides energy?
The report points to bullet choice and how comfortably a shooter can practice with and control a rifle. Hunters also need to consider the intended game, conditions and safe shot placement; the gel test does not make those decisions for them.
