Hey guys, I just bought an X7 Phenom and I am experiencing accuracy issues. When I first received the gun I did a complete field strip and re-greased everything. When I shot it the first time I just made sure that it didn't have any major issues like leaking air or paint blending, so I didn't pay much attention to the accuracy. I just took it out again today and noticed that the accuracy was terrible. I couldn't hit a tree consistently at 30 yds and a lot of the balls were completely veering off target anywhere from 3 to 6 feet. So I decided to do a grouping on a box at 25 yds and here is the result:
It wouldn't be so bad if half the shots didn't miss. Out of the 20 I shot, 12 hit the box. Of those eight that missed, 5 were nowhere near it. It's like I had an apex on high ramp or something. I used Draxxus competitive series, so its not the best paint, but it shouldn't be causing performance like this. I am also running the stock barrel. When I re-greased the internals, I removed the velocity adjuster, so I am not sure what the fps is currently. Could the velocity being to low or high cause this?
I don't know if its related, but when I took it out today and started shooting, the gun would make a whistling sound after each shot, like it was venting from being over-pressurized. After the whistle I listened for leaking air and couldn't hear anything. I eventually found out it was coming from either the top of the ASA or inside the grip. I removed the tank and re-attached it and the whistling stopped. Don't know what it could have been or if it is related to my accuracy issue.
Any help y'all could give would be awesome.
