This video is part 3 of my chrony testing series of some of my pellet guns. I call this my Crosman 2240 Tactical. The base pellet pistol was purchased from Mac1 with their accuracy prep. I also had a 14 inch barrel installed and a steel breech. The muzzle brake is from TKO and the stock adapter is from Mellon Air. The stock is a Tippman 98 paintball stock. For optics I'm using a BSA Red Dot.

Wingman,

I'm curious about how close your muzzle is to the front of the chrony? I can't really tell from the angle in the video.

The main reason I ask is that I've been told and have experienced it myself with my 2240 carbine, that if I'm closer than around 3 to 5 feet from the end of the muzzle to the first sensor on the chrony that the blast of Co2 messes with the velocity readings. I own an Alpha Chrony, so I don't know if that makes a difference with the sensors (I wouldn't think so) or not. Even when I shoot my PCP's over it I try to be about 2 feet from the sensor, minimum.

Anyway, any information or comments you could add to help debunk or prove this would be appreciated. Thanks.

I've gone paintballing and they put the muzzle close to the chrony. So to answer your question I'm not sure. I've shot it close and a few feet away and I had very close or the same readings. On my video I was a bit crowded as I wanted the camera to capture the action and the reading on the chrony. I will try it again soon but I can tell you it's pretty close. I've shot the airgun on other chrony's and the fps was withing 4 or 5 fps. As always thanks for checking out the video and commenting.
