The the accel preamp is now set to 10mv/g so that would be 100g/V. I haven't really spent any time piecing the whole thing together yet. My motivation for this project is basically to find out what the rifle scope sees as impulses.My only claim so far is that the pellet exits between the 2 big recoils. If the second recoil can be attenuated significantly it won't help the pellet, but would sure help the scope. The rest of the data can be generally squabbled about and I'm certain there's plenty for all of us to learn. Thanks for what you've posted so far and keep us informed of your discoveries as they are unearthed.
