I continue to be impressed with the Lehigh Defense 194 grain Maximum Expansion bullet.Mgoirea wrote:Lehigh 300BLK is more effective than any .45ACP round out there. Mainly because they get a long bullet to work with. However, it's still operating in the momentum regime, which isn't what I'd want a gun to do, especially one as big as a rifle.
It is a true marvel of modern engineering and is currently the only projectile that I would trust for subsonic 300 BLK home defense.
There are plenty of videos on YouTube showing terminal ballistic tests if you are interested.
A nice unplanned feature of this bullet is that it is also barrier blind.
Meaning, the projectile stays in tact while punching through such things as wood & sheet rock, and will then reliably expand after entering soft tissue.
This is a double edged sword though.
It is entirely plausible that this bullet could miss its intended target in you home, travel through your several walls in your home, enter the wall of a nearby home and achieve expansion after impacting a sleeping neighbor.
There is a new player in the subsonic expanding 300 BLK market as well.
The subsonic 300 BLK Trident from G2 Research shows some promise.
There are some cool YouTube videos that show some ballistic testing.
I would wait until it has proven itself as reliably feeding in an AR.
Subsonic 300 BLK home defense can be reliably achieved.
The cost of these projectiles / ammunition is considerable though.
Lehigh Defense 194 Grain ME Ammunition is $50 per box of 20 or $77 for a box of 50 unloaded bullets.
That works out to about $1.54 per projectile or $2.50 per loaded round...
