My 5.6×61mm SE, an abbreviated form of its full designation. Case is a Bertram.
The 5.6×61mm [Vom Hofe] 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 as also does the .22 Savage Hi-Power, unlike the more common .224-in bullets used for most .22 centrefire cartridges.
5.6×61mm VHSE ammunition is still available (2007) 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.
