If you’re not in the know about 8.6 BLK, here’s the scoop: it’s a cartridge born from the 6.5 Creedmoor case, necked up to 338 caliber. Why does it catch the eye of hunters and shooters?

The 8.6 BLK is extremely versatile and suppressor-friendly, thanks to supersonic and subsonic offerings. And let’s be real, those subsonic options pack a punch, thanks to hefty 280-grain projectiles, a fast twist, and innovative expanding designs that shred flesh.

What makes 8.6 BLK so versatile? It slides right into AR10/SR25 mags and your run-of-the-mill short action mag boxes. No fuss, no hassle.

8.6 BLK Selous Machined Expander Projectiles

Now, let’s get to the star of the show: the 8.6 BLK Selous Machined Expander projectiles made by Discreet Ballistics, a company in Wyoming. These bullets are CNC machined from solid copper and are designed to expand between 1050 and 750 FPS.

The pinch point near the ogive ensures expansion occurs reliably, whether its impact is in bone, flesh, or both. This expanding projectile makes the most of the rotational kinetic energy from the 1:3 twist barrels that 8.6 BLK is so well known for.

Tests show immediate expansion at 950 FPS with 19 inches of penetration in calibrated gelatin. Still, this projectile holds onto 100% of its mass post-expansion. Preorders are live, and these projectiles ship in the first quarter of 2024.
