I made a fancy looking recoil slide for testing recoil of rifles with different weights of bullets and with different brakes installed.  I put a chronograph just past the slide.  On July 15, 2007 I tested a few rifles.  I have since, but didn't record them.

 

Here are enough to get an idea how different weights of bullets affect free recoil travel.  Which translates into usable information.
