[3] The .375 Swiss P is advertised by RUAG Ammotec as a cartridge that "fills the gap in ballistic performance between the .338 Lapua Magnum (8.6×70mm) and the .50 Browning Machine Gun (12.7×99mm)".
The .375 Swiss P shares its bolt face, rim diameter and overall length and maximum operating pressure with the .338 Lapua Magnum chambering.
[5] RUAG Ammotec claims that the .375 Swiss P FMJ low drag projectile load offers performance superior to their .338 Lapua Magnum offerings, exhibiting additional supersonic range and reduced wind drift, while delivering greater kinetic energy down range.
[6][7] The manufacturer states .375 Swiss P ball is loaded with a double base smokeless powder and the projectile has a 0.8014 (ICAO) G1 ballistic coefficient under International Standard Atmosphere sea level conditions (air density ρ = 1.225 kg/m3).
[8] With an AP-type projectile the .375 Swiss P is claimed to be able to penetrate the body armour of German Protection Level IV from a distance at ranges up to 600 metres (660 yd).
