Currently classified bullet type called "SN",or 7N44.Calibre 12.7×108,front core Rockwell hardness is 67.Rare core is hardened lead alloy.Overall weight of the projectile is 71.4 grams.In my own 14.5 version of it the weight will be reduced so it will have the straight tail(like BS41)and I estimate it's weight to be 58.5 grams,and as I will use another propellent called"Nitro-penta gewehr rohrpulver",it's initial velocity will be 1280 metres per second(4200 FPS),and it's energy will be 48 kilojoules(35.4k ft lbs),so I estimate penetrating ability of this new round type to be 65 millimetres(2.6 inches)of continious AR-550 armour steel plate.
