Labradar

I set up for dry fire last eve and did a measurement on the Labradar. 12 Inches to the right side of the barrel and 16 inches back from the muzzle on the .223 and 14 inches back for the .260 which only has a 24 inch barrel

With a 10,500 mAh power pack I used less than 25% by disarming between strings over a 2 1/2 hour session

Tomorrow I will see if it will pick up .22 LR without going to a air rifle sensor
 
I'm thinking of training a dog to fetch my unit back from the range. He'll be a Labradar Retriever.

The airgun microphone should handle even suppressed .22's.

I am not all that interested in tracking .22 anyway. This is just a experiment to see if the unit will do it without needing external mic. I will start off with the internal mic, if it won't trigger I will try the dopplar, if that does not work, set it for pistol if that does not do the trick then I will know if I ever do want to track .22 I will need the external mic. If I were really interested in .22 LR velocity data I could use my optical, not that I really trust it now after comparing it's data to the Labradar's data. Eight years of dirt roads in the back of a Jeep took it's toll. I just hope the Labradar lasts that long

I just put my old CZ 452 a new stock, put a good scope on her and changed the trigger to a Rifle Basix. Tomorrow is zero the scope and play with some exotic (for me) ammo day. Also want to make sure this scope will get me to 200. I will be mostly shooting CCI standard velocity and I did a ballistics workup. It will be fun to see the SD's of high dollar vs $3.00 a box ammo though if I can get the Labradar to pick it up.

One of the interesting things about the 22 LR is the expansion ratio is so great that chamber tolerances have little effect on the final velocity of the bullet. The powder has burned and the gas expanded fully enough that bullet acceleration ceases at 16 to 19 inches and then it starts to slow. But there is enough pressure that it slows very gradually, with the result that velocity tends to be pretty consistent regardless of rifle barrel length in the usual 16 to 24 inch range. Thus, for as long as I can remember, match ammo has been used as a calibration check, tending to be within 50 fps of the label velocity in all rifles.
 
Love mine and use it a lot. Ive only used it for pistol so far though. I havent had to test anything new yet for rifle.

This morning it would not arm and then lost power altogether. The USB connector seems to have went bad and that was the final straw for me. It eats AA's rapidly so without a external power pack it is about useless in my opinion

Labradar gets 2 thumbs down from me. Grats to those that can get them to work, they are way to frustrating for me to consider a replaceing it with another one until a new and improved version hits the streets. I want something that works as advertised. first time and every time. It is a great concept but my early adopter days are over. I will wait for version 2 or a competitor to come up with a more reliable model. I have never in my life tried so hard to get something to work, I really wanted to like this thing but too many issues.

It has been packed and a return label printed and tonight I will order another Pro Chrono. My last one rode down many a dirt road and jeep trail and was 1/5th the cost of this thing and still worked reliably for 8 years

Oh well another 500 to use for my 6 x 47 Lapua project
