Experiment: Recoil vs. Muzzle Velocity

The barrel and the entire gun must stretch and flex while firing. That flex will store some acceleration.

Also consider that multiple bits of the gun are mechanically attached to each other. It looks like the accelerometer is attached to the barrel, whereas the majority of the rearward forces before bullet leaves the barrel is acting on the bolt. Even as a bolt action, there's plently of interesting mechanical interfaces to absorb energy and movement before transferring to the barrel.

Thanks. In the PRB post that I cited, it's noted that recoil force can be "in excess of 1,000 pounds", but that "the recoil event is very short, lasting only about 10 milliseconds". So yes, I suspect that the gun is absorbing most of that elastically, and then relaxing on a longer timescale.
