sk ptr m/94 prj m/41) – meaning 6.5 mm live cartridge m/94 projectile m/41 sniping Sweden, which remained neutral during World War II, decided during the early 1940s to develop a new ball projectile for the 6.5 mm m/94 cartridge intended for sniping and sharpshooting, specifically for weapons such as the m/41 sniper rifle. To improve accuracy and ballistics the new projectile was designed as a spitzer bullet, a design which had previously not been used in service for the 6.5 m/94 cartridge. The new cartridge was loaded with a boat tail spitzer bullet (D-projectile) fired at a muzzle velocity of with muzzle energy from a long barrel. The new spitzer cartridge was adopted from around 1941 onwards. As the original round-nosed m/94 projectile was obsolete in comparison, the new spitzer projectile came to replace the old m/94 projectile as the new service ball cartridge almost immediately upon being adopted. Blanks Swedish blanks or lös patron were loaded with bullet shaped wooden projectiles that were painted red. To fire these blanks the Swedish military used a blank firing attachment (BFA). These adapters were mounted on the muzzle and designed to shred the wooden projectile as it exited the muzzle to prevent injuries to nearby people and to allow functioning of automatic weapons. A wooden blank designed to fire rifle grenades was also designed. It was used in a dedicated rifle grenade launcher based on the Remington m/67-89 (originally chambered for 8x58RD) called Krevadkarbin m/16 (blast carbine m/16). The Krevadkarbin m/16 was outfitted with a "rifle grenade cup" at the end of a very short barrel for the wooden blank. Pressure The Swedish 6.5×55mm military ammunition had, according to their ammunition registry of 1960, a normal average pressure of with the exception of tracer rounds (slprj m/39 and m/41) at and armour piercing (pprj m/41) at . Note that the method of measurement is not stated. The book Norske Militærgeværer etter 1867 cites the standard ammunition as having a standard working pressure of measured with a copper crusher.
