I had a Lyman dispenser (6000 I think) . Two failures, one was replaced.
No more Lyman (and generally I like Lyman stuff)
Now I have a Hornady dispenser and the entry RCBS Chrargmenaster Lite. Both work, the RCBS very well and no failures so far.
The Hornady while reasonably accurate and consistent is slow. You also have to set data into parameters to get speed and accuracy. That is both a pain and s it does nto hold settings when you cancel a charge to change it (several parameters you can play with to get speed and accurate dispensing). I will keep it but not my go to.
The RCBS is both fast and has none of those adjustments and generally its both faster and accurate without the messing around. Quick and easy to use and set.
The only thing I do not like is the the right power button. Its raised and its easy to brush and then it just turns it off. Annoying. A short delay like a computer and the Hornady before shutdown would correct that. I may build a cover. As it is I put it on the right side (Lyamn 2000 and the case tray in the middle) and that keeps motion further away from the button.
So, I vote for the RCBS Chargemaster Lite. I got both on good sales. I like having two in case one dies (ergo twice with the Lyman). The Lyman 2000 has a trickle built on so that is my last gasp backup.
I also have a Lyman 2000 scale I use as a cross check.
Ok, a bit of a rant on scales. It sounds complex but once you do the following its not.
Scales drift. The RCBS and Hornady have auto correct but it can be a bit behind. I have had them drift off 2-4/10 of a grain.
While I go with the original zero, after than you just weigh you powder dispensing pan and write down its weight on the pan (several places you do wear it off)
When you go to reload, you zero that. When you take it off (powder or no powder) what is left should be the pan weight in a negative number.
If it drifts 1/10 up or down that is ok, I cross weight it with the Lyman 2000 and its still spot on.
If it goes 2/10, then its iffy and 3/10 for sure. I just re-zero any time its off even a tenth.
That is you cross check, each time you lift the pan off, check the negative weight showing.
I also use the Lyamn 2000 for weighing cases, bullets I am not sure of and various other odds and ends, very useful too. Unlike a beam you don't have to screw with the slider stuff.
For instance, Barnes is supposed to be RP brass. While it may be, it does not weigh the same as RP lable 30-06 brass. So I set it aside to use in the throw away cases (mil surplus guns and the hunting guns I don't shoot as much)
I admire those who still use a beam scale, I don't have the patience
If I am reloading 50 cases (usually) then I run both dispensers with their own pans as well as the Lyman 2000 with its own pan.
I check the Lyman 2000 the same, lift the pan and check its negative weight is what the pan has on it.
Randomly from either dispenser I dump a charge on the Lyman 2000 to see if it agrees with the dispenser.
If I am in super accuracy mode I double check all charges.
