Lab Measurements

Berger has a reputation for excellent bullets. Berger’s 133gr Berger Elite Hunter bullet is no exception, and our lab measurements agree. The uniformity of diameter, length and weight help with consistent bullet flight and load development.

Here’s the summary of the lab data we collected for these new bullets:

These results are very consistent with other bullets we’ve tested from Berger including the following:

Test Setup: Rifle and Optics

This was another occasion to use our custom 25 Creedmoor rifle built by Gavin Gear:

Please review the rifle build here.

Test Scenario: 25 Creedmoor with N555 and Berger 133 Elite Hunter


Here’s a summary of the components used to test this new bullet:

  • Lapua 6.5 SRP necked to 25 Creedmoor
  • Berger 133gr Elite Hunter Bullet
  • Vihtavuori N555
  • Federal 205 small rifle primer

Above: Vihtavuori N555, a newer powder from Vihtavuori that’s ideal for Creedmoor-class cartridges.

also used were the LE Wilson Mandrel and Inline Seating Die, and the Primal Rights Competition Primer Seater.

Velocity and Accuracy Summary

You can see from the results above that best accuracy was had at 42.0 grains, and best velocity/consistency was at 42.5 grains. We are thinking to try the EC Tuner Brake with the 42.5 grain load to see if we can get the best of both worlds (velocity and accuracy).

Here’s a nice 5-shot group shot at 100 yards, at 42.0 grains of N555:

Ballistic Gel Testing

One of our favorite things to do is shoot ballistic gel. These gel blocks combined with the Edgertronic High Speed Camera provide a lot of information. The wound channel can be examined statically and the bullet extracted and examined for expansion and retained weight. 

We use Clear Ballistics Gel to determine bullet expansion and penetration. While synthetic ballistics gelatin will not 100% reflect what a bullet will do to a human or animal, it provides us with valuable data and allows us to compare the performance of different bullets and different loads.

This Hornady 7mm 150gr CX Bullet penetrated 33” at  3200 fps.

American-made Clear Ballistics Gel is reusable. It can be melted down and utilized again for even more tests. Consult ClearBallistics.com to view all of their offerings!

Test 1: 2800 fps “Full Velocity”

We started our test at full velocity, which for this load was right at 2800 fps:

Above Berger 133 gr Elite Hunter Bullet Full Velocity Cavitation, a “massive” impact

The high speed bullet mushroomed very well and weighed in at 84.2 gr, and so retained 63% of the original bullet weight.

Test 2: Absolute Minimum Velocity: 1800 fps

The 1800 FPS bullet study was designed to mimic a shot at approximately 800yds, A very long shot, one I don’t believe I would take on an animal. However we wanted to show the results. Watch the video and see if you were as surprised as we were. Our thoughts were that the bullet would lodge in the first block. That did not happen as you can see here:

Above: Berger 133 gr Elite Hunter Bullet Down Leveled Velocity Cavitation

The bullet did not expand much and traveled much farther into the second block than the high velocity bullet did! Due to a lack of expansion the bullet weighed in at 127.6gr  for 96% weight retention. Interesting results.

This makes us wonder what the results would look like at 1900 fps or 2000 fps! I’m betting we’d see more expansion. For comparison, we shot the same type of ballistic gel with a 6.5mm 143 grain ELD-X bullet from Hornady, also at 1800 fps and observed a near identical result (very little expansion, and long penetration distance).

Thanks to Clear Ballistics for the crystal clear gel. This product allows for superior high speed camera action! See our previous use of the gel blocks in the Hornady bullet test here.


What do I like about the 25 Creedmoor 133gr Berger Elite Hunter? You get a flat trajectory bullet with less “large” caliber recoil but it provides a much bigger impact on target over say a .22 or 6mm caliber bullet. 

This is another one of those rifle cartridges that you can take to a competition, shoot it all day and not be “beat up” by recoil. Then you can take the same rifle and get your hunting load (Berger has a 133gr Elite Hunter) and harvest varmints and deer size game. 

This bullet will demand a fast twist barrel. Our rifle we are testing with is 1:7. Most “off the shelf” rifles have a 1:10 twist which will not stabilize this bullet. Your local gunsmith will likely be able to help with a custom barrel installation.
