    You have made my day again. Now I need to buffer the return in order to be able to test rifle with scopes attached. As It stands now, the sled rest against a solid stop. And I would assume the return...

    I've installed the spring as you suggested and the results are very consistant now. A 308 win without the break recoiled 1.096, 1.075, 1.104. With the break .689, .683, .692. I'm now thinking of...

    where can this all day special be had? This is a short budget project. $200 is ok if it includes the load cell and the data collection software or what is needed to store the data. A very nice piece...

    load cells and data collection are expensive are they not? I did try an accelerometer circuit board from Analog Devices but the frequency response was not fast enough. It needs to capture a 6ms event.

    I have tried a weighted carrage, 50 lbs with no spring and the results were not as consistant as the spring loaded version. I've also tried a hydraulic damping system using a one way actuator and a...
