I have had a Chargemaster Lite for several years now, and like it a lot. I think it is faster for doing load work ups, where you’re constantly changing the powder charge, or for small batches of ammo. For me the cut off is about 20 or 25 rounds; more than that, and it is usually faster to take the time and calibrate the powder measure and then just throw all the charges at once. My unit does have a difficult time with super fine ball powders like Big Game and Hunter. It tends to throw slight over charges with those. It works fine with stick powders and coarser ball powders like 760.
