Finally got a chance to start work up of a hunting load with my 257 STW and 92gr. Hammer bullets. I had been using TTSXs but lost one deer last year and had a very poor blood trail with no exit wound on a 90 yard hit on a second deer.
Long and short of it is that the Labradar, as advertised, will not track and record when velocity gets much over 3900 fps. However, it will track over 3900 at times. I have obtained readings of 3907 and 3917. Each of these readings were the first shot after cutting the unit on. Each time it would not track any shots over 3900 after tracking the first shot. I will see if this is just an anomaly or if it is possible to track one shot of 3900+ after powering the unit on and off.
I talked to the manufacturers and they say that the 3900 limit is a hardware limitation, not a programming limitation. I took that to mean that to increase the fps ability would require more sophisticated (and expensive$$$$$) hardware.
I had no problems tracking the load up to 3900. Ultimately, if you want to develop loads for anything over 3900 fps, look elsewhere.
