Shown here is a charger of ten Swiss 6.45mm Gewehr Leuchtspurpatrone 80. What is/was the rifle which these cartridges were made for. They exist, in quantity in ball, tracer, blank and drill. They can be seen packed in 20-round white cartons and were selling for 20 Swiss Franks per carton a couple of years ago.
The Swiss had continued to use the excellent 7.5x55mm GP11 cartridge in both rifles and MGs and still use this cartridge in MGs. Then along came the 6.45mm followed quickly by the 5.6mm Gw Pat 82 (in essence 5.56x45mm). I can understand the Swiss producing both 7.62mm and 5.56mm cartridges and weapons from a commercial point of view, these calibres can be exported. However I don’t see any advantage in them adopting either of these cartridges when the 7.62mm offers no ballistic advantage over the 7.5mm and the 5.56mm is overdue for a change.
