Impulse Measurement Device: Measuring forces created by rimfire ammunition

Impulse Measurement Device: Measuring forces created by rimfire ammunition

Shooting rimfire firearms is popular due to cost, recoil, and availability. Autoloading rimfires use shot energy to cycle cartridges. Cycling failures costs the shooter time and money. Chamber pressure curves are available, but there is little other information correlated to reliable cycling. Our goal is to build a fixture to quantify the axial and radial forces during firing, to better understand how they correlate to proper cycling in firearms, allowing manufacturers to reduce failure rates.
