I received a Pact chronograph from a relative as a gift and finally had achance to try it out. The instructions say to place the starting edge 8 feet from muzzle of rifle and adjust the height so the bullet passes 5-8" above the sensors. I shot 15 rounds and only got one reading. It was at dusk so I'm not sure if the lighting was an issue or if something else was a factor. I also noticed that my groups were slighly right of center while shooting thru the chrony. Once I moved it out of the way I was back to center, Anyone else have any experiences such as this? The one and only velocity measurement I did get wasn't close to what the reloading manuals show as approx. velocity. I'm confused, could somebody Please help me out. Thanks.
