Jæger 4,5 XPR – equipped with a regulator. Maximum achievable projectile energy under optimal air consumption and acceptable grouping is 25-30 joules. Best results are achieved with JSB Exact 4,5mm 0,54 gr (optimal velocity from 270 to 300 m/s up to 60 shots with 200 bar in a reservoir) and JSB Exact Heavy 4,5mm 0,67 gr (optimal velocity 270-285 m/s up to 60 shots with 200 bar in a reservoir). These pellets produce groups under 20-22 mm at 50m distance. Bullet velocity adjustment is achieved by rotation a main spring screw. Increasing power to 30 joules requires a regulator re-adjustment and could be performed in a workshop. The operating reservoir pressure range is 300-120 bar. Stable shooting is achievable until 100-110 atm.
