The 8.6 Blackout 342gr ammo — the Pork Shredder Punisher Series — is the heaviest hammer in the caliber’s subsonic lineup. Built around a patent‑pending 342‑grain CNC Swiss‑turned solid‑copper expanding projectile, it’s engineered for maximum subsonic mass and deep, decisive terminal performance. When you want the biggest, hardest‑hitting quiet bullet 8.6 Blackout can throw at close range, this is the load.

Maximum subsonic weight
At 342 grains, this is about as heavy as practical subsonic 8.6 Blackout gets, and that mass is the whole point. Momentum scales with bullet weight, so a 342gr projectile at subsonic speed carries more of it than any lighter load — driving deep through hide, muscle and bone to reach the vitals. For the largest‑bodied hogs and situations where penetration is paramount, this 8.6 Blackout 342gr ammo brings the most authority the cartridge offers while staying quiet.
The CNC Swiss-turned expanding projectile
Each Pork Shredder bullet is CNC Swiss‑turned from solid copper — lathe‑machined rather than swaged — which delivers exceptional concentricity and consistency, the foundation of accuracy. Unlike a match bullet, this is an expanding design built for terminal performance: it opens on impact to transfer energy and create a substantial wound channel, while the all‑copper construction retains weight for deep penetration. It’s a genuinely modern hunting projectile, and the reason this load hits so hard for a quiet round.
Built for the biggest hogs
This 8.6 Blackout 342gr ammo is a hunting and defensive load aimed at heavy game and maximum penetration. It excels on large hogs at close range, where its weight and expanding copper bullet anchor tough animals decisively. Because heavy subsonic bullets drop fast, keep shots inside the cartridge’s close subsonic window and place them on the shoulder/vitals for the cleanest results. For help choosing between weights, see our guide to the best 8.6 Blackout subsonic ammo for hunting.
Lead-free and suppressor-ready
The solid‑copper construction makes this a lead‑free load, suitable for non‑lead areas, and held below the speed of sound it produces no sonic crack — through a .338‑rated suppressor it’s quiet as well as hard‑hitting. That combination of heavy, expanding, lead‑free and quiet is exactly what suppressed big‑game hunters look for, and it’s the heart of the 8.6 Blackout concept.
Rifle and suppressor pairing
Run this load in any properly chambered 8.6 Blackout rifle — AR‑10 or bolt action — with the fast 1:3‑class twist needed to stabilize its long, heavy bullet. On a gas gun, suppressor back‑pressure helps cycle the low‑pressure subsonic load; confirm reliable function and a dedicated zero before you hunt.

342gr vs 285gr: which should you choose?
The two heavyweight subsonic 8.6 options come down to priorities. The 285gr fracturing load is the balanced all-rounder, a touch flatter and more versatile. This 342gr Pork Shredder is the maximum-penetration specialist, the round you choose when you are after the largest hogs or simply want the most momentum the cartridge can deliver quietly.
Neither is wrong; they are tuned for different ends of the same hunting mission. If your shots are close and the animals are big and tough, the 342gr is the decisive choice.
Why heavy and slow hits so hard
It can seem strange that a bullet moving around 975 FPS, barely faster than many pistol rounds, can be such an effective hunting projectile. The answer is momentum. A 342gr copper bullet carries a great deal of it, and rather than relying on velocity-driven expansion that fades as the bullet slows, it keeps driving forward, pushing through bone and muscle to reach the vitals.
Pair that deep-driving momentum with an expanding copper design that opens to transfer energy, and you understand why this 8.6 Blackout 342gr ammo hits far above what its modest velocity suggests.
