I have a PACT chronograph that is a bit cumbersome to set up but I've successfully used it since 1985 with rifles but I simply cannot get any readings when I try to chronograph handguns.
The recommended distance from the muzzle to the first sensor is 70 inches and both sensors should be 4 inches below the bullet path. The bullet path window under the sky screens is about 4"wide (bottom)x 12" wide (top) x 13" high.
I've not tried to graph any bullets smaller than .44 (180gr) and .45 caliber. (250gr; 300gr). I can't understand why the unit can't see these fat bullets.
Any ideas?
