I have been using the RCBS Chargemaster for years, and honestly, I have been satisfied with its performance, but like most hobbies, I am looking for better, faster. I have been eyeballing these two and was wondering which, in your opinion, is better overall, and I should buy? Thanks for your help
First of all, please be certain to update the thread with your final decision, whichever way you go. Let me begin by stating that I own both the ATV4 and a Gen2ST. They’re both recent acquisitions for me, and I have spent considerable time with each in the past few weeks.

The ATV4 was as simple as can be to set up and get started with (a suggestion would be to add the “riser mod” made by
@JustDreaming on this forum). That is a VERY worthwhile addition! The ATV4 simply does what it’s supposed to do with the approximate precision and repeatability of a metronome. I’d call it “boringly” accurate and reliable. Yes, you have to use an app to control it, big frickin deal. Who doesn’t have multiple extra devices (tablets and old smartphones) laying around. Just set one up next to your AT and it’s “problem solved”, your phone is still free to do phone things while you reload.
The Supertricker is another story. Tons of fiddling, tweaking, menu diving, firmware updates, as well as copious amounts of back-and-forth with the “ST owners” FB group. Incidentally you get a lot of communication from the makers of the ST on there, as they’re both quite active on the FB groups. Yes they can be rude (they’re foreign) and they’re SUPER proud of their SuperTrickler so they don’t take criticism well. Suffice it to say, the ST is a handful. I sort of regret my decision to buy it, but at the same time I DO enjoy it when it’s performing optimally. The problem is it takes work, and time (like A LOT), to get it doing what you want it to. If you like to “geek out” on every single detail and nuance of the powder dispensing operation, get yourself a ST. You’ll always feel like you’re beta testing a piece of lab equipment.
In conclusion, if I’m recommending one over the other, it’s the ATV4 over the ST all day, every day. It’s cheaper (by a lot), more reliable, usually as fast or even faster, and it’s built like a thousand times better (IMO). 99% metal construction vs 99% plastic, you be the judge on that. Also, I did not pay any duties or tariffs on either the ATV4, or the scale, which both get shipped from Canada. Granted, I bought the ST from a forum member so there were not duties or tariffs (for me) on that. However, I did have to buy the heavier scale platform directly from SuperTrickler (due to scale drift with their severely underweighted standard platform) and not only was it like $70 shipped, I got hit with $40 extra in duties and fees from UPS. I can’t imagine how much it would be on a $1500+ SuperTrickler/scale purchase!
It pains me to say it because the ST does have tremendous potential, but at the end of the day, I’d suggest steering clear of the SuperTrickler. If you want to dispense gunpowder for the purpose of reloading and shooting, get a V4 AutoTrickler, if you want to dispense gunpowder as a hobby or as a “laboratory experiment”, get yourself a SuperTrickler and go nuts!
