Yes, I ditched the RCBS Chargemaster 1500 and went for a target master along with a set of Lee dippers...
I got fed up with over and under throws when using longer extruded powders and ended up double weighing everything with a beam scale to speed things up...
The target master is much more accurate and repeatable, consistent to the kernel every time but way too slow to throw a rifle load from start to finish.. hence the Lee dippers. The dippers let me dump to within 1gn then press the button on the Target master and it finishes it off. While it's doing that I am getting another bulk load in the dipper...
I find it MUCH, MUCH quicker than the RCBS and MUCH more consistent/repeatable.. isn't subject to EM interference as it's optical, doesn't need to warm up for 30 mins, doesn't suffer from drift (unless the earths gravitational field shifts but touch wood... up to now!
) The only downside is it is a tad more fiddly to set up as you have 3 things to organise rather than the one with the RCBS... but we are talking an etra minute setting up, not an hour... Oh... and it's battery powered too so is portable!
Wouldn't go back to an RCBS or Lyman now... I have found my automated loading nirvana!
