Knowledge is everything mode. The Ke ratings means more to me in most scenarios. That good old Kinetic Energy or thumper is what counts. BTW, I have mine set at the exact same distances.I have the labradar , and I do like it . could you guys clue me in to what the down range velocities are used for . I have mine set for 25 , 50 , 75 , 100 yards . other than muzzle velocity readings , I'm lost on the purpose for the down range velocity info . thanks Jim
My understanding is that you can use the information to calculate a BC for the bullet, if you were so inclined.I have the labradar , and I do like it . could you guys clue me in to what the down range velocities are used for .

It needs to see the bullet to the target from the muzzlebeen thinking about buying a Labradar but i have a question has anyone used one inside a shooting house and would a 8 inch wide by 12 inches high window hole big enough for the Labradar work ? the window hole the barrel is out is about 16 inches away .will the Labradar work then ? thank you,Pete53
Do you have a BC calculator on your website?? I'm using JBM currently http://www.jbmballistics.com/cgi-bin/jbmbcv-5.1.cgiYou can calculate BC, as others have said. This is a risky proposition because the range is so short, but it does appear to work very well the times I have done it, and I know some shooters who report similar results. I'm guessing it works better with some bullets than others, but for bullets that match up well with the standard drag functions, it's surprisingly accurate. Berger's heavy bullets tend to match up with the box number very well. Others may as well - I haven't tested many. My own bullets calculated out to .316, and the labradar put them at .317.

The LabRadar does not need to "see" the bullet from muzzle to target. In fact, Vo is calculated from the downrange velocity measurements, rather than measured directly, which is the primary reason for the various downrange velocity measurements.
I don’t, but the one I wrote works exactly the same way - there’s not much to it. The JBM one is good.Do you have a BC calculator on your website?? I'm using JBM currently http://www.jbmballistics.com/cgi-bin/jbmbcv-5.1.cgi
The LabRadar mathematically extrapolates a muzzle velocity from down range measurements. I dont know thier exact method, but I would guess it uses a few points. It doesn’t need to see it all the way to the target. In fact, it can’t in most cases.Having a hard time parsing your statements. I'll ask my questions one at a time.
How is the Vo calculated "...from downrange velocity measurements, rather than measured directly,..." if those measurements are not taken?
And how does "...which is the primary reason for the downrange velocity measurements." fit in if those measurements are not taken?
No matter how I tear your statements down and re-read them, in order for them to make any sense, there must be measurements taken downrange, which is directly at odds with one of your claims.
