Hey Guys,
I have a new Labradar Chronograph that my wife got me as an anniversary present. I had a couple of problems that I worked out. I was able to get it to read .45 ACP and 10mm just fine, but the real problem came when I attempted to test my .460 S&W Magnum. I received an error message for all but 1 of my 5 shots. That 1 shot read a velocity of 2,447 fps. That's not possible. I was shooting 300 grain XTPs and my load data said it should be around 1,700 fps. I am sure I am setting this up incorrectly. When shooting firearms of this power, how do I get accurate data?

Are you shooting with the porting behind, beside or in front of the Labradar?

Are you shooting with the porting behind, beside or in front of the Labradar? I had the whole gun in front of the chrony with the muzzle about 12 inches forward and roughly 12 inches to the right of the gun. I set it at 18 inches. The manual mentioned using a block between gun and chrony, should I try this? |

When I was doing research on how to set mine up I read how different muzzle breaks affect the shot being tracked. If I remember correctly it has something to do with how the ports are angled in the brake. I've watched quite a few youtube video's showing the muzzle break forward and behind the sensor of the radar. I'm sorry I don't have any real life use shooting handguns with muzzle breaks. Happy Shooting! Boats

Any vibrations will cause it to long track correctly. We run ours on quad pods and shoot under them or tripods. The little stand you can buy is not stable enough for most things that have blast. With out large rifles and muzzle breaks, using the tripod or quad pod is the best way we have come up with to not lose shots.

I was using a pretty stable one that day, but I'm wondering if perhaps maybe the cylinder gap set it off. My range has concrete tables that prevent me from being directly under the chrony |

Okay, so I finally got it figured out for the .460 S&W Magnum. I had to move the Chronograph 12 inches to the side and about parallel with my elbows. The setting was at 6 inches, and on Handgun velocities. After that, it read all but 2 rounds out of about 30. That is no big deal.
