now I don't see how I can load develop without one.
Totally agree! I would be lost without it. It tells me just as much as the group does, maybe more.
I need to talk to the Missouri Department of Conservation (they run the public ranges around here) and suggest that they get some chrono's at the range to use. They bore sight rifles for free, and they have spotting scopes to use, why not have some chronographs at the ranges as well!
Well, I give it a week or less before someone puts a bullet where it's not supposed to go (into the chrono). It is very easy to hit the chrono, and most people at a shooting range have a hard time hitting stuff at 100, let alone through a hole in line with the target. I guess if you got a deposit, then why not!
