Measuring felt recoil.....


I have a desire to measure rifle recoil as felt by the shooter.   Yeah.... It's a mad scientist kind of moment.

I was thinking I may be able to use this force sensor, and my Vantage graphing multi-meter to make this happen.  Fix a thin steel plate to the rifle butt, tape the sensor in place, and fire the rifle with the butt against a fixed and firm sandbag.  Perhaps a thin plastic strip will need to be applied over the sensor to better relay the firce of the recoil.

If it works, I should be able to read both peak and duration of the recoil event graphed out.

My goal is to accurately measure the changes in rifle recoil as related to different muzzle brake designs, and other changes in the weapon.

Thoughts?

Looks interesting. I'd suggest sandwiching the sensor between two pics of plastic in addition to the steel plate. It looks a little delicate and might be damaged if there's any relative movement in the contacting materials that would cause rubbing. I look forward to the results.

That was supposed to read two pieces of plastic.

Be interesting to see how your numbers compare to calculated recoil.

5 or so years ago someone did that type of test in the USPSA magazine Front Sight. I believe he had a lead sled or similar rest done up on wheels so he could measure deflection from recoil. It was mostly comparing compensators on 5.56 rifles so the overall recoil wasn't the point, just the comparison. It may have had some means of measuring muzzle rise too.

Vuurwapenblog used a stick-on device that approximated and graphed pressure inside the barrel... curious to know if it was similar to this device.
