The "best reloading investment" got my attention. Given the number of times I read about "velocity" being a big deal, I was surprised so few people mentioned a clock as a good reloading expenditure. So...
I have always loaded for group, used a ladder technique while loading at the rifle range. Yet I wonder if I could save some time if I got a basic chronometer so I could track speed changes and deviations, know when I'm getting "on the cam" for various powders.
Your thoughts, kids? Thanks.
