The ammunition was provided by the company for this review.
Recently, I was offered the opportunity to test the Lehigh Defense Tipped Controlled Chaos (TCC) ammunition.
Upon carefully reviewing Lehigh Defenses extensive selection of calibers and bullet weights, I chose .308 Winchester.
Lehigh Defense’s Tipped Controlled Chaos (TCC) load is designed to not expand or fragment in a barrier, but rather in fluid. Shown with Model 2020 Waypoint rifle in .308 Win.
In particular, I selected the 155-gr.
TCC round with the listed velocity of 2,800 feet per second (fps) tested in a 20 barrel.
These petals then radiate outward away from the bullets initial trajectory path, resulting in a massive energy spike.
The author tested the Lehigh Defense .308 load in the Waypoint rifle with a Ransom Diamond Series Rifle Rest for maximum stability to determine the round’s accuracy capability.
So, thats the chaos.
What about the control?
As noted earlier, its only when it impacts fluid that it expands, doing its intended job.
The 155-gr. TCC round from Lehigh Defense proved to be a very capable performer in the bolt-action Model 2020 Waypoint rifle.
After careful consideration, I chose theSpringfield Armory Model 2020 Waypoint riflein .308 Win.
with a carbon fiber-sleeved 20 1:10 twist barrel and finished in Ridgeline camo.
The optics mounting system consists of a Picatinny mount in the Model 700 pattern.
The Lehigh Defense TCC ammo is versatile and suitable for a variety of uses. The author tested the ammo in a Springfield Armory Model 2020 Waypoint bolt-action rifle.
To further keep weight to a minimum, the stock of the rifle is also of carbon fiber.
Now that the rifle was selected, I needed to get a good optic.
Weight of the variable-power scope is 36.8 oz.
Ballistic gelatin used by the author captured the bullet’s performance. The velocity results of the testing were gathered by aGarmin Xero C1 Pro chronograph.
Finally, I needed a sturdy rest to wring out the best accuracy performance of the ammo.
In the past, I have used the Ransom Rest Multi Cal.
So, I reached out to Ransom Rests about a new series they call the Diamond Series Rifle Rest.
The author’s Springfield Model 2020 rifle chambered for the .308 Win cartridge served as the test platform for the Lehigh Defense ammunition. The rifle has a 20″ barrel with the SA Radial Brake.
I asked to try out the front and rear rest systems.
He kindly helped me set my rifle up for the first trip to the range with it.
Boy, was I impressed with this ammo/rifle/scope combination.
My groups measured .700, .695 and .640, for an average of .678.
These were some very solid results, and well within the Model 2020s accuracy guarantee threshold.
Next up was testing for velocity.
So, I was curious how the Lehigh load would do.
Remember that Lehigh lists 2,800 fps out of a 20 barrel.
The best way to do this was to use ballistic gel.
The FBI Standard for ballistic gel is 6x6x16.
I used the Clear Ballistic Gel 8x8x18 block of gel as I wanted a larger medium.
After calculating my offset, I fired one round into it.
After the dust settled, literally, I inspected the block of gel and was stunned.
TCC ammo, makes for an exceptional trio.
