My experience with a thrower was that I found variances on the long powders to be closer to 1.0 grains than 0.5 grains. I never could get comfortable with it. I would go through the progression of load development to find that perfect charge, then my thrower would miss it by a full grain. It was more than I could handle. I bought the Chargemaster when it came out (then an updated version) and have used it every since. I modified my loading procedures to the Chargemaster. I admit that I never compared accuracy with weighed loads versus thrown loads.
Within the last several years I have all but quit load development with a new rifle. I decide on a proven load and give it a whirl. If accuracy is acceptable I'm done. I don't sweat the time, money, or barrel life for that .2" better accuracy.
Johns article is not new on me, it just made me re-think it. The thrower definitely sounds more attractive to me now.
Not only that, the discussion here sold a subscription to Handloader. Win/win!
