6mm ARC – 108 gr OTM – Federal Gold Medal (GM6ARCBT1) – 200 Rounds

Precision shooters who run the 6mm ARC in an AR-15 want match ammunition that holds its zero from box to box, and a full case is the way to get it. This listing is Federal Gold Medal 6mm ARC 108 grain Berger BT Target open tip match ammo, MPN GM6ARCBT1, sold as a 200 round bulk case. Buying 6mm ARC ammo by the case means one production lot for load development notes, practice sessions, and match days, so your dope stays consistent through the season.

The heart of this load is the 108 grain Berger BT Target bullet, a boat tail open tip match (OTM) design known for a very high ballistic coefficient. A high BC bullet sheds velocity more slowly, which means a flatter trajectory and less wind drift at long range. Federal rates this load at 2,650 fps and loads it in Federal brass with Gold Medal match primers, held to Federal’s strict specifications for accuracy, pressure, and velocity. For steel at distance, PRS style gas gun matches, and long range practice, that combination is what makes Gold Medal a benchmark match ammo.

The 6mm ARC (Advanced Rifle Cartridge) was developed by Hornady for the AR-15 platform, and it fits a standard AR-15 lower and magazine well with a 6mm ARC upper, bolt, and magazines built for the cartridge. It is also chambered in bolt action rifles from makers such as Ruger and Howa. A common question is whether 6mm ARC is the same as 6.5 Grendel. The two share a parent case, but the 6mm ARC is a separate cartridge, so only fire it in a barrel marked 6mm ARC. Open tip match bullets are built for accuracy on paper and steel rather than controlled expansion, so this is a target and competition load. A 200 round case supports a full practice block plus a match or two.

Federal Gold Medal GM6ARCBT1 is new production ammunition, not reloads. Each cartridge uses a brass case with a boxer primer and is non-corrosive, so normal cleaning is all your rifle needs. The boxer primed brass is reloadable, which makes these cases worth saving for handloaders. This case comes in factory packaging as 10 boxes of 20 rounds for a total of 200 rounds of 6mm ARC 108 grain OTM.
