I got a chronograph when the price point came down to about $100. What an educational, enlightening and sometimes frustrating experience.
After a few years, I packed it away and haven't seen it this century...
What it showed me was that the book velocities are about right, allowing for the differences in different guns, and a handful of fps is irrelevant for my shooting. I don't care about SD/ES numbers, it the load groups well in MY gun(s) that is what matters to me.
