| In the late 1960s to late 1970s, many
countries worked on different ideas as part
of a joint NATO program to find a cartridge
of less than .22" Diameter or 5.56mm caliber. The 4.6 x 36 mm cartridge was one of 4 or 5 different calibers of cartridges used in the H&K, for the HK36 (not to be confused with the current 4.6x30mm for the HK MP7, nor with the current HK G36 5.56mm rifle) There is also the capillary problem with the really small bores; any water which gets into the barrel will be difficult to dislodge. A couple of interesting experiments were the 4.6x36 HK for the HK36 rifle featured a 'spoon tip' to the bullet to encourage tumbling on impact. |
