The Hornady Lock-N-Load® Auto Charge TM is an extremely useful tool for the beginning or serious reloader. It is great for a hand loader wanting to quickly dispense the same precise charge again and again, or to vary charges with a given powder for accuracy or velocity testing. This unit is quick to setup, easy to use, and extremely accurate to +/-0.1 grains. Highlights include a 1000 grain scale capacity, quick setup and calibration, 3 speed settings to accommodate different powder types, a large and easy to read backlight display, manual or an extremely useful automatic dispense option, trickle function, and over charge protection.
