Wilson Combat 300 Blackout 220gr HPBT Subsonic – Superb 20 Round Box

Description

A suppressor only does half the job. If the bullet breaks the sound barrier, the crack travels downrange regardless of how good the can is, and the shot is loud to everyone but you. The Wilson Combat 300 Blackout 220gr HPBT subsonic exists to close that gap.

What Subsonic 300 Blackout Actually Buys You

At 1025 feet per second this load sits comfortably below the speed of sound at any temperature you are likely to hunt in, which is the whole point. Loads advertised at 1050 or 1075 feet per second can creep supersonic on a hot afternoon or out of a longer barrel, and the resulting intermittent crack is the most common complaint about cheap subsonic ammunition. Wilson Combat leaves margin on purpose.

The projectile is a 220 grain Sierra hollow point boat tail, an open tip match design rather than a hunting bullet. Its G1 ballistic coefficient of 0.629 is remarkably high for a 30 caliber bullet, which matters more at subsonic speeds than most shooters expect. A heavy, slippery bullet holds its modest velocity better and produces a more predictable drop curve, and the Wilson Combat 300 Blackout 220gr HPBT is genuinely capable of consistent hits well past 150 yards for a shooter who has done the drop work.

Wilson Combat loads this in Berryville, Arkansas, with American brass, American bullets and clean-burning low-flash powder. Clean powder is worth real money on a suppressed gun, where every bit of unburned residue ends up blowing back into your face.

Muzzle energy is roughly 513 foot-pounds, which is in the neighborhood of a hot 45 ACP. That is an honest way to think about this load. It is a heavy, slow projectile that kills by penetration and placement, not by hydrostatic shock, and inside 100 yards on hogs or deer with careful shot placement it is effective and remarkably quiet.

Cycling is the practical issue. Subsonic 300 Blackout generates very little gas, and most rifles need either a suppressor mounted or an adjusted gas system to run it reliably. If your carbine is set up for supersonic ammunition without a can, expect short stroking. This is not a defect in the ammunition, it is physics, and it applies to every subsonic 300 BLK load on the market.

Cases are reloadable boxer-primed brass, which suits this load well since subsonic charges are gentle on brass and shooters who go quiet tend to shoot a lot of it.

Honest Notes on Running Subsonic

Buy the Wilson Combat 300 Blackout 220gr HPBT subsonic if you shoot suppressed and want ammunition that stays quiet in every condition rather than most of them. The extra velocity margin below the sound barrier is what separates this from budget subsonic loads.

Skip it if you are shooting unsuppressed and your rifle has a fixed gas system. It will be quieter than supersonic ammunition but not quiet, and it may not cycle. Buy a supersonic load instead until the can arrives.

Skip it for anything past about 150 yards on game. The drop curve steepens sharply and the terminal energy is modest. This is a close-range tool used deliberately, and pretending otherwise wounds animals.

Running the same rifle unsuppressed? The Wilson Combat 300 Blackout 110gr V-MAX is the supersonic counterpart, and the Federal American Eagle Suppressor 220gr is a higher-volume practice option in the same weight. Sierra publishes full MatchKing bullet data on its own site.

MAG5 Firearms stocks subsonic and supersonic 300 Blackout, plus the barrels and gas components that make both run in one rifle. Ask if you are not sure your setup will cycle subsonic.
