Often overlooked by noob reloaders. A chronograph is very handy to verify your loads are performing as expected.
One could easily buy $10,000.00 worth of reloading gear and components, and STILL want more. I'd love to have one of those high end automated ammo plant presses. Not to reload because I shoot a lot, but because they remind me of a Rube Goldberg device. Like the game mouse trap. It's like the ultimate gadget.
