My red wolf.22hp shoots the jsb monster @ 960, but the group poi starts to drop @ 196 bar. I have never did a shot count outside temperatures does have an effect!
Mine gets about 40 with the 25g redesigned. 930fps
i always fill my bottle to 260 bar off air tank. By the time I bleed and disconnect the gauge on the RW is back down to <250. I was losing a few shots if I cut the tank off at 250 on the gun. Risk I am willing to take.
My experience is exactly like cyclone’s though my rifle also shoots the 18.3 Gr AA/JSB pellets lights out on medium and low power at 50 yards, giving 150 shots or more at 30 ft lbs.
Also if you choose to shoot slugs the nsa 26gr shoot very good. The jsb monsters @960 and the 26gr slugs have the same poi out to 100yds the slugs are going out @920. They are a tight fit at .218 but are working great.
