I have a chargemaster and an A&D/V4, and an old Lyman 1000 that's about 30+ yrs old, and a Hornady M scale. The Chargemaster was a splurge about 10 yrs ago, I am happy enough with it, does what is needed, it's pretty consistent and I get maybe 1in10 bad throws on it, which is bearable to me. I got the A&D/v4 as I wanted to see if I really could detect any difference in the paper results, so far, no, nothing concrete showing up. For my 22cal stuff, I use ball powders anyway, so, setup the Redding thrower and check it on the beam scale, go from there. It's faster than the Chargemaster or the A&D/V4 in the long run, by the time the electronic setups warm up, I have a good bunch loaded already. All I want from them is minute of gopher head inside of 300yds. There are small batches I use the beam scale for still, the Lyman gets used for sorting cast bullets. Neither the chargemaster or the A&D were necessary, but, were splurges, one for laziness, one for satisfaction of an OCD question in my mind.
