Corbon Performance Match Subsonic .308 Winchester 185 Grain Full Metal Jacket Ammunition (MPN: PM308S185)
Product Description
Shooting precision bolt-action or tactical semi-automatic rifles chambered in .308 Winchester with a sound suppressor often presents a significant acoustic challenge: traditional high-velocity match loads break the sound barrier with a sharp, loud crack, generating intense muzzle blast and heavy shoulder recoil. Corbon eliminates this operational friction with their Performance Match Subsonic .308 Winchester 185-grain load. Engineered specifically to stay below the speed of sound, this specialized match cartridge provides precision marksmen and suppressed rifle enthusiasts with an exceptionally quiet, ultra-consistent round designed for tight target groupings.
Proudly loaded in the USA to strict benchrest tolerances, this centerfire rifle cartridge features a heavy 185-grain Full Metal Jacket (FMJ) boat-tail projectile. Corbon carefully meters specialized, clean-burning propellants to keep velocities consistently below the subsonic threshold while ensuring complete powder combustion to prevent unburnt particle buildup inside suppressor baffles. Every round is seated into first-run, match-grade virgin brass cases fitted with ultra-responsive Boxer primers. The uniform brass casings provide an airtight chamber seal to prevent blowback gas around the action, ensuring smooth mechanical cycling and long-term durability for handloaders at the reloading bench.
Out on the range, this subsonic .308 load delivers a dramatically reduced recoil profile compared to standard supersonic match rounds, allowing shooters to maintain clear optical sight pictures and execute rapid follow-up alignments. Leaving the muzzle at a uniform subsonic velocity of 1,050 FPS with 453 ft-lbs of kinetic energy, it produces a whisper-quiet acoustic report when paired with a quality sound suppressor. The heavy 185-grain match bullet profile maintains excellent flight stability and predictable downrange tracking. Packaged in a 20-round box, it stands out as an elite choice for quiet target diagnostics, suppressed precision training, and tactical marksmanship.
*Armorer Bench Notes & Technical Maintenance Guidance: Centerfire rifle ammunition procurement regulations strictly apply. All purchasers must be 21 years of age or older and assume full legal responsibility for adhering to local, state, and federal laws. Due to commercial carrier transit restrictions, ammunition cannot be delivered to Alaska, Hawaii, or US territories. Deliveries destined for California and New York must ship directly to an authorized FFL dealer or registered ammunition vendor. Residents of Illinois must supply a valid FOID card alongside a matching state ID prior to order processing, and localized regional bans prohibit delivery to specific jurisdictions inside Illinois (including Chicago), Massachusetts, Connecticut, and Washington D.C. Armorer Tip: Subsonic .308 Winchester loads feature a steeper trajectory drop than standard 2,600+ FPS supersonic match loads; establish a dedicated elevation profile on your scope turrets for subsonic distance ranges.
