5.6×61mm VHSE
The 5.6×61mm SE, an abbreviated form of its full designation, the 5.6×61mm Super Express, is a rifle cartridge introduced in Germany in 1937. It is based on the 6.5×55mm Swedish cartridge.
The '5.6×61mm SE' uses a.228-in diameter bullet from Walter Gehmann, Karlsruhe, Germany. No mass-produced rifles are currently offered in this chambering, but custom rifle makers will chamber for it; and the calibre has a loyal if specialised following, especially among handloading long-range hunters of roe deer and chamois, although the cartridge has accounted for very much larger deer and antelope.
