Hatsan AT44 QE in .25, the short one. I just got my regulator installed this week and finally set up to my liking. 27 shots, or 3 clips @ 800fps on a 3200 psi fill. Its taken me a few goes at it getting the reg set just right on account of having to degas and refill with a hand pump for every reg adjustment. Finally got it setup hitting 800 (which I think is about max for this gun/reg combo) and it happened to be sighted in at 18 yards which is close to where I would have landed my first zero anyhow. The center of the target was the first clip (9) and I was aiming more to not hit my new chrony than actually at the target. The numbers I got had me so tickled as I saw the consistency. HI:807 LO:804 AV:805... I rushed to change the clip I noticed the group that I wasn't aiming at was all inside of 1".. Then it struck me and I wanted to see what kind of accuracy I had if the consistency was that good so I picked the end of one of the legs on the target and dotted the i. Then I did it 5 more times.. I was barely paying attention to the chrony at this point but I did note that it was displaying readings all in 805-799. Those 6 shots went in that larger hole. I was thinking there is no way. I must have missfired or something, but no way I just landed 6 in what looked like the only hole. So I says fine shoot somewhere else and see. I decided to place a shot right next to it because I thought if there really is that much precision now I should be able to see it with a fine adjustment. I saw the new hole and thought ok do it again, so I emptied the clip (2 more) into the new hole. I know its only 18 yards but boy am I impressed with the consistency and accuracy now. I can't wait to get out this weekend and stretch out further than the back yard
