My new " old " 700mm impact barrel

Thats where my impact likes 34g. I just installed xtwist 700. Really tighten up group from standard twist 600mm. I`ve been running 135. On reg. You dont have any trouble getting 860 @105 bar? That should increase your shot count. I believe ill try it.
shot most of day (250 pellets) in a heck of a wind. Steady 12mph w/gusts of over 20. With a little hold over i was hitting pellet tins @ 110 yds consistently. Had to wait out the hard blows but the 700mm firing 34g @865 powered thru the steady blows.

Sounds like you're on the right path. Nice Job

My .25 Smooth Twist (not X), is also terrible ! Even on MIN power I have huge groups at 50 meters. I do not have camera mount, so I can't look for spiral in slow motion, but it has to be. Have you given up on the .25 old barrel, or will you keep looking for a setting that does work? My Wildcat .25 shoots great at 899 FPS , but my impact just sucks.....

It is disappointing to get a $2000 air rifle that isn't accurate. I feel your frustration. I questioned my purchase to the point I thought about selling it. The first thing I had to realize, I can't shoot like Matt and Ted! Owning a Wildcat is like owning a Lexus. Man a great car and just get in it and drive. An Impact is like an Indy car. It has to be checked mechanically and tuned for every track condition. Constantly monitored and tweaked This took me several months to realize and learn. Watch Ted , Matt, and Esting Rowe. The education will greatly reduce the learning curve.

​My Wildcat 22 is pellet on pellet @ 25yds, 1/2" @50, and 2" or so @ 100yds. Virtually no flyers @880 fps. 25g. But, the wind is a killer on 22's. 

​Now dealing with Impact. First loosen the shroud and reseat your barrel, the barrel should seat in the breach and you should be able to catch a finger nail on it sticking thru.
​Clean the barrel, I thought mine was clean until I stuck a bore scope down the tube (I'm a safe tech so I have such things) and could not believe how dirty it was. this improved my accuracy 50%. Esting shows you how to tune your power. mine likes 130 on reg. level 4. 855-870 for 34g pellet. I haven't had time to shoot the 24g. (cheaper to shoot) 
EVERY RIFLE IS DIFFERENT.

​the new twist x 700mm (it is long!) took me to pellet on pellet @50, 1 1/2 @100 ( I atribute that to my shooting, it will get better) with pellet on pellet not unusual. I've only been shooting it since Tuesday. No flyers, that sure is a change. So Windy i can't really get a true accuracy check. maybe tomorrow. .

​Hope I helped.

Mine did not group well either it had a bad barrel , I sent it back and got a different brand here was dropbox , of the pellets wobbling, I did shoot some good groups , but many groups had fliers and it was not ammo it was if I timed the wobble to hit the target , I agree with the impact is not just a buy and shoot gun here is pics of targets and clips of pellets in flight to see bad barrel , it had tiny stress cracks at twisted end and barrel
