need to ask you some questions about what's been happening with my Impact. So I recently returned my gun and was shooting hole in hole at 30 yards at 886-891. Below was my spread which I thought was pretty good. Nine shots. First reg 150 second 114, macro 14 micro 3.5 and valve just below 4. This was on Saturday. I didn't shoot Sunday.
Shot count: 9
Low: 886
Hi: 891

Today (Monday) I went out to hunt some doves. I shot a 50 and 70 yard shot right on center mass. Dead! I noticed the gun was unusually quiet. The pellets also didn't go through the bird like normal. So I pulled out the chrony ..To my surprise, the shot fps was at 840! Consistently through about 15 pellets So I had to increase the macro to 15 and valve to 4 to get back to 880-890. This has happened in the past as well where I lose fps after the gun sits a day or two. I shoot many shots after the tune to make sure it holds before I put it in the safe. My first reg fluctuates about 40 - sometimes 50 bar difference. I don't think I should have to Re-tune my gun every time I take it out, correct ? I am going through a ton of pellets to try and keep my gun at 880 since it keeps dropping. Second reg was at 114 but is now at 120 with a digital gauge. Didnt change it today
Thanks for any insight on this. Just wondering why I am losing FPS from one day to the next on the same tune.
