Default Labradar Chrono work on 17 and 20 calibers?

I posted this question on AccurateShooter.com but no responses. I want to buy a Labradar but their only distributor (Richard Moser) can not assure me it will work for fast 17's and 20's. He personally has used the device with 17 HMR and said it works pretty well but does not pickup some shots. I question how it will work with the 17 Hornet which is another 1000 fps faster than the HMR. He does not know if the manufacturer has tested the device with 20 calibers. All he can offer is that the manufacturer tested it at 3900 fps with a "small bullet", caliber unknown. Is anyone using this device with success on 17 and 20 calibers over 3500 fps?

You posted an interesting question. I am sure that you have seen this chart.
Looks like the range of measurement is limited but the it is much further than a standard Chronograph. It does see BBs.

From LabRadar web site.

What range performance can one expect with LabRadar?
In general LabRadar will typically measure the velocity of a 7.62 mm projectile from muzzle up to 100 yards. After extensive testing of a variety of calibers you can expect to obtain velocities at these distances when in the Standard Power Mode. Low Power setting will have about 30% less tracking*.
.177 Pellet - 30 yards;
.177 BB - 30 yards;
22 LR - 60 yards;
223 - 60 yards;
270 - 70 yards;
308 - 80 to 100 yards;
9mm - 130 yards;
40 S&W - 130 yards;
45 ACP - 130 yards;
500 S&W - 130 yards;
12 gauge Slug - 90 yards;
Paint Ball - 50 yards;
Arrows - 50 yards;
* Since every bullet has a different profile your results may vary. In general, the larger the base (excluding the boat tail) the great the distance the projectile can be acquired.

No reason in the world that an optical chronograph will not work at any range you can get the bullet to pass though the measuring window area without putting a hole though the machine.

Labradar is not optical...it uses doppler radar. If it reliably picks up our small caliber bullets it will be a big improvement over existing chronographs.
