For SBR applications we suggest using our 194gr Maximum Expansion bullet over this
— The projectile is machined from solid bar stock. Expansion only occurs upon impact through hydraulic energy. (They only expand when they hit “wet.”) This is not a frangible bullet produced from powdered metal.
For rifle use only.
For performance and safety purposes we only recommend the use of OEM manufactured 300 AAC Blackout/Whisper brass.
Not recommened for use in factory Remington 700 rifles chambered in 300 Blk.
All of the Lehigh subsonic 300 Blackout/Whisper ammo and .308 subsonic bullets are designed to be stable in 1:8 twist barrels. Many of our customers also use the 170gr Controlled Fracturing and 194gr Maximum Expansion bullets successfully in guns with 1:10 twist barrels. We have had several customers with stability problems with our subsonic bullets and ammo in Remington 700’s chambered in 300 Blackout. We do not know if this is due to the land/groove ratio, grove depth, barrel surface quality, bore diameter, groove geometry, twist lead error, etc. We are completely focused on providing products with optimum terminal performance and until we understand the issue with this gun platform we are notifying customers of the potential problem.
Lehigh originated Controlled Fracturing Technology. These bullets are designed to deliver maximum terminal performance. Controlled Fracturing bullets are produced from either solid copper or solid brass and are pre-stressed at specific points so that after a predetermined penetration depth, the razor-edge petals deploy, releasing an energy spike and then separate and radiate outward from the primary path of the bullet. The bullet shank, now back to bore diameter, continues penetrating straight and deep along the initial impact path.
Unlike traditional expanding bullets which mushroom and dramatically limit the bullet's penetration and provide only one wound path, Lehigh's Controlled Fracturing ammunition creates an initial energy transfer, multiple wound paths, and a deep penetrating base – a far more effective bullet.
In hunting applications, this unique terminal performance provides multiple projectiles which will penetrate vital organs and blood vessels, increasing the amount of tissue damage and leading to more blood loss. In addition to the damage these petals inflict, the main shank or base of the bullet is designed to penetrate the off side hide creating a better blood trail should you need it.
Our Controlled Fracturing bullet offers another distinct advantage. Since you are getting multiple projectiles radiating out, away and forward from the primary bullet path inside the animal, the Controlled Fracturing bullet compensates for small point of aim - point of impact errors. Imagine that buck fever causes you to pull your shot so that it strikes two inches from the heart or lungs. With the Controlled Fracturing bullet, it will be almost impossible for one of the petals to not penetrate these organs.
In personal defense applications, Controlled Fracturing technology is the most effective way to neutralize a threat. In an extreme high stress situation, where shot placement is likely not going to be perfect, this technology provides multiple wound channels coupled with a large energy transfer and a deep penetrating base, meeting all of the requirements for stopping a threat instantly.
