You can also switch back and forth between rifles and keep track of each shot string for each rifle. For example I've shot 3 rounds with one rifle and let the bbl cool, then switch the Labradar to a Series 2 string and shoot 3 rounds with a second rifle, then switch back to Series 1 for the first rifle.
Because I'm a fuddy-duddy I usually just write the velocity down in my load data book. I'd have to read the manual again to remember what buttons to push..........
