The 6mm HAGAR Cartridge |
The new Hornady 6mm HAGAR brass is hard at the base but well annealed at the neck. The brass has a small primer pocket and a small flash hole. All of these features enable the brass to hold pressures well and to remain serviceable and usable for multiple re-loadings. Great Brass!

A 6mm AR-15 Cartridge with Factory Brass The 6mm HAGAR is a 6mm cartridge that was specifically designed for use in an AR-15. Recently Hornady has made brass for the 6mm HAGAR under a special contract. This brass is exceptionally well made and very consistent and is in stock. The 6mm HAGAR has a case capacity (approx 37.5 gr. of water weight) that allows it to be an awesome competition round for high power and also and exceptional varmint and hunting round. The 6mm HAGAR has been used to win the National High Power Rifle Championships on multiple occasions (most recent at Camp Perry 2012 Nationals). We are now building 6mm HAGAR uppers in match rifle and varmint/hunting rifle configurations. |
