Jæger 5,5 XPR – equipped with a regulator. Maximum achievable muzzle energy under optimal air consumption and acceptable grouping is approximately 40-45 Joules. Best results are achieved with JSB Exact 5,5 1.04 gr (optimal velocity from 270 to 300 m/s up to 50 shots with 200 bar in the air tank) and JSB Exact 5,5 Heavy 1.17 gr (optimal velocity 270-285 m/s up to 40 shots with 200 bar in the air tank). These projectiles group under 20-22 mm at 50 m. On average, factory tests produce groups of 15-18 mm. Bullet velocity adjustment is achieved by rotation of main spring screw. For increasing power to 50 joules a regulator re-adjustment is needed which could be easily performed in a workshop. The range of reservoir operating pressure is 300-120 bar. Stable shooting is achievable until 110-120 atm.
