I have an Impact in .22 with the 700mm barrel. I bought this to shoot slugs but as I turned up the power for the slugs I noticed the gun became more violent and hold sensitive. The gun was accurate but only if i did my part well. I use this gun for hunting and when I was out in the field it was more difficult to do my part. Long story short. I added power mods and dialed the power down to shooting nsa 24.8gr at 930fps. Now the gun is crazy accurate. Sub moa is easy work and the hold sensitivity is minimal. Mods are 6.3mm valve, power plenum from Poland, double port transfer port, reworked probe, and a delrin spacer with a rubber washer behind it. Reg at 105-110 bar, hammer on 4, and barely kissing the valve adjuster. All the violent harmonics added by increasing the power are gone. The shot feels like a factory pellet pushing gun and the shot count is crazy high.
