Kyreb Posted April 11, 2006 Share Posted April 11, 2006 (edited) Short story: I recently upgraded from a standard red to a standard green Chrony. The results from the green one seem "quicker" than those from the old unit and various club chronographs I had used in the past. I ran some Winchester "White box" 180 TCs over it yesterday. Average velocity was 1022, PF 184. It was 80 deg F, sunny , low humidity. (for Houston in April) Jeff Maass pages give 1046.8 velocity and 190.PF. No firearm data listed. Just curious if anyone else had ever run a check on this stuff. Rick UPDATE: Last night at the local Tuesday night match two other competitors brought chronographs. We set them up in sucession and I tried my loads. Short Story: My suspicions were confirmed. My Chrony is registering right at 100 FPS faster than it should be. Looks like I will be on the phone with them today. Edited April 26, 2006 by Kyreb Link to comment Share on other sites More sharing options...
Gregory_k Posted April 16, 2006 Share Posted April 16, 2006 fed amer egale 180 runs 1032 out of my edge. my reloads were 950 fps in the winter, but know they going 1055. After I burn this 2k I am going to drop some powder and see what I can do. Link to comment Share on other sites More sharing options...
Vlad Posted April 16, 2006 Share Posted April 16, 2006 Your best bet is to chrono the same loads over two or three different chrono's at the same time so you get an idea how your chrono's measurments compare to other ones. And what someone lists on a webpage as velocity is not what you should expect from your gun. Barrels make a big difference. Link to comment Share on other sites More sharing options...
.40AET Posted April 17, 2006 Share Posted April 17, 2006 I had a green one that ran 60 fps faster than anyone elses chrono. As others have stated, check it against a chrono that you trust. Link to comment Share on other sites More sharing options...

This is almost exactly where I think mine stands. I hope to get a chane to compare it with some other chronos to confirm. Just have not had the chance.

.40AET Posted April 17, 2006 Share Posted April 17, 2006 If you just got it then send it back. Your lucky to find out the problem now. I went minor the year that I bought mine. I got no where with the company. I have since bought a CED and have been dead on with the chronos at major matches. Good luck. Link to comment Share on other sites More sharing options...
Kyreb Posted April 19, 2006 Author Share Posted April 19, 2006 I have had the thing awhile. Over the last year, I have been finishing up a degree at night school and relocating to Houston, I have not had much chance to work with it. I am seriously thinking about offering it on EBay and buying something more trustworthy. Link to comment Share on other sites More sharing options...
