I got it in .177.25 and .30 but no chronograph yet, but speed is not a issue I came across yet. That's the beauty with the impact, that is so adjustable.
I only got 2-300 pellets shot with the . 30 before I got tierd if filling so much air all the time for my plinking, so I had some serious fun with the .177 2500+ pellets shot so far, and I just put on the .25 to experiment a bit in the 3 hours of daylight I get at the moment. And that's what is so cool with the impact, so versatile so adjustable. My wife keep telling me that me and Chuma (my impact) have a unhealthy relationship, but me and Chuma know that she is just jealous on our relationship and that she would never understand
I have the 22 and 25. Just getting aquatinted so still testing and adjusting. Started with the 22 and was able to adjust up in speed until accuracy suffered. Don't remember, but above 1000fps. Got the 25, 34 grain up to 850fps. but found slack in the power adjuster that needs adjusted out. That's where I left off. Hoping to get 900fps
That's what I was afraid of with my current bobcat 30 I'm getting 875-885 on my chronograph I really don't want to go to a slower gun but I love the looks of the impact but thinking maybe I'm better off just buying a wild cat in 22
I have both 30 and 22 cal, the 30 is shooting @870fps and the .22 @850fps I use two different scopes for each caliber so I don't have to change or make new adjustments if I was using only one scope for both calibers. With the .30cal i can hit 1 1/2 inches pigeon clays @ 100 yards all day when weather allows it I think the Impact's performance shooting the 30s at this speed is good enough for plinking and hunting, great accuracy and significantly quiet.
