11mm Pin fire
The production for this ammunition were running during 1943-44 and it was expensive for the time, 1,20 SEK per piece, equivalent to 24 SEK in today's value. The high price was due to the exclusive material in the core, tungsten carbide, and the difficulties to form this material.

The ammunition was issued for snipers, and at 1956 each sniper was equipped with 40 pieces of PPRJ and 40 pieces of sniper grade ammunition prj m/41.
The PPRJ ammunition is not of sniper accuracy, it is really an AP ammunition to gain a better capability against hard targets. The accuracy is given as within 18cm2 at 100 meters as an average, tested in 200 series, shot with 10 rounds in each series in the delivery tests. Also, the trajectory is different between the PPRJ and the standard 6,5 m/41 projectile, so the shooter needs to readjust the point of aim when used. The ammunition is intended against lightly armored targets as personnel carriers or shields at artillery.
The only indication of use outside the sniper category is the AmReg 1943 catalog for the marine. Here it shown up for both rifles and all of the marines machine guns. The publication after, 1946, the AP is removed from the marines AmReg again. This short period of display on the catalog makes me wonder it it was actually introduced in the marine, or if this was only a intention.
Even if the PPRJ cartridge generates a higher Pmax of 3500 atm compared to an standard m/41 ammunition that has a Pmax of 3300 atm, the PPRJ can be used in all of the 6,5 mm weapons in use in the Swedish army.
The penetration capacity of the 6,5 PPRJ is actually better than that of the AP of the more powerful round, the 8x63. The core of the 6,5mm PPRJ projectile has a better form for penetrating hard targets.
The V25 of the 6,5 PPRJ in a m/96 rifle is 950 m/s to compare to the V0 of 8x63 PPRJ that is 810 m/s.
As some examples can be mentioned a penetration for 100 meters and 90 degrees impact angle results in:
140 mm of concrete
16-17 mm of HB 500 steel armor.
28 mm of HB 130 steel plate.
The same test for 300 meters and 90 degrees impact angle results in:
120 mm of concrete
8 mm of HB 500 steel armor.
22-25 mm of HB 130 steel plate.
In 1956 there were still 3.800.000 PCS of PPRJ on stock.
