Whether you are a nerd for all the stats and details or you want to see the action with your own eyes, we have you covered. Both technical statistics and real-world performance are greatly important to our testing process. You may be wondering, what is chronograph data?
What is chronograph data?
Simply, Chronographs are used to measure time periods and provide data. A chronograph is a particular type of watch that is used as a stopwatch. This stopwatch function combined with a display watch is what creates this time recorder. The word ‘chronograph’ means ‘time recorder’. When we test out ammunition, we test the feet per second, which is known as FPS, of each shot to generate accurate chronograph data.
Although lab chronograph data is intriguing, what it really comes down to is real-world performance. So that is exactly what we did with Desert Tech.
Putting the .308 Winchester to the Test
We partnered up with Desert Tech for this testing with the use of their high-end rifles. They provided SRS M2 precision rifles to compare the chronograph data from True Velocity’s .308 Winchester 168-grain Nosler Custom Comp to Federal Gold Medal Match.
Why We Chose The SRS M2 Precision Rifles
When choosing a rifle for testing, we searched for the highest quality and precise rifle. We chose a 22 inch 308 Desert Tech SRS M2 precision rifle. This was chosen because it is the latest iteration of the stealth recon scout family of rifles. It is a Bullpup precision rifle with bolt action. The SRS M2 precision rifle is a multi-caliber with an assortment of match-grade barrels. An assortment of match-grade barrels makes it extremely accurate. This rifle has an excellent trigger, providing all the components for shooting accurate rounds, perfect for round testing.
What We Are Testing
We tested the performance, accuracy, and consistency from shot to shot. We tested to see the standard deviation of each round as well. Let’s not forget that we are recording chronograph data.
The Outcome
Below is the data collected from shooting 5 shots of Federal Gold Medal Match and True Velocity’s .308 Winchester 168-grain Nosler Custom Comp through the SRS M2 Precision Rifles.
Federal Gold Medal Match Data
- 2602
- 2599
- 2583
- 2593
- 2583
True Velocity’s .308 Winchester 168-grain Nosler Custom Comp Data
- 2683
- 2664
- 2672
- 2679
- 2678
Detailed Comparision
| Average Muzzle Velocity | Extreme Spread | Standard Deviation | |
| Federal Gold Medal Match | 2592 | 19 | 7.899 |
| True Velocity’s .308 Winchester 168-grain Nosler Custom Comp | 2675 | 19 | 6.615 |
As you can see from the data displayed above, the results are rather amazing. Both of these rounds are very consistent. We use the Federal Gold Medal Match as our control group.
When we look at the True Velocity’s .308 Winchester 168-grain Nosler Custom Comp data, we can see that the Average Muzzle Velocity of 2675 which is about 80 feet per second faster. That is notably faster! Additionally, the slightly lower deviation of 6.615 is extremely low. True Velocity polymer cased .308 Winchester ammo is comparable to leading ammo today. It is extremely accurate and high velocity. Not to mention polymer cased ammunition is far lighter than the leading ammunition.
Our team at Virtus Ammo strives to test our polymer cased ammunition as in-depth as possible. We are continuing to test and compare the polymer cased ammunition to other manufacturers’ products. It is crucial to the Virtus team that we see how our ammunition stands next to other leading ammunition. The Virtus team is working on obtaining additional types of data and different tests constantly.
