Reloading scales?

I wouldn’t think it would be in the same reliable class as the FX because it’s more of a strain gauge type instead of a magnetic balance.
So what does this equate to? When using only one scale the Linearity/Bias error can be ignored since the same scale is used for all weighing. What matters is the display resolution and the repeatability. Between the Fx and the EJ the readability is the same (0.02 gn) and the FX repeatability SD is 0.001g (0.0154gn) and the EJ is 0.003g (0.0436 gn). When that is converted to a precision meaning what the scale will read for the same weight weighed many times 95% of the weights will be within the range. The FX will read +/- (2x0.0154)gn+.02gn) or +/-0.05gn. The EJ will read +/-(2x0.0436gn+0.02gn) or +/-0.11gn.

Probably just less headaches with drifting issues is what it equates to. Thus the purchase price difference.
 
Maybe for some shooting disciplines a 0.1 grain difference in powder can make a difference but I can tell you for my experience using extruded powders, it makes no measurable difference on target especially as case capacity increases.

There are so many variables, several of which are beyond the shooter's control such as environmental conditions, that attempting to gain a minute improvement in powder charge precision reaches a point of diminishing return.

That's not to say that one should not carefully prepare consistent reloads but at some point, it reaches a point of diminishing return on time and expense. In my experience, the shooter's skill and environmental factors are the most significant variables.
 
I was considering the A&D EJ-123. Anyone have any experience / advice on that model?
I considered that model but ended up bowing to the wisdom on this site. There are a lot of compelling arguments here to make your wallet REALLY light. It was worth it. I probably saved the value of the FX120i in time saved within a year of purchase. Using the FX120i is FAST, it's not really mentioned much how much time the scale can save. I have young kids (2.5y and 9 mo) so my time is valuable to me.
 
Well, it sure sounds like FX 120 has some positive feed back. My RCBS digital will keep me busy for now, especially because I just got a small shotshell loading setup and Im playing with 12ga #T and #F for coyotes.

My will be working a bunch more in another month or two, I will get one then.

My electric system is just off grid solar, Ive got 120v coming from a high quality pure sinewave inverter that should match the grid electric. Even if there is some drifting, its resolution hopefully makes up some difference, +/- .02gr is darn good for me.
 
Has anyone rigged up a hand trickler with the A&D by drilling through the plexiglass sides? I think I will buy the scale soon but probably can't afford the auto trickler for awhile.
Before I got the Dandy I had a manual trickled sitting on the piece of wood on top of the scale. I drop in a powder cup with the Harrells and then trickle up with the Dandy.
I tried dropping the powder with the cup on the scale but there were too many kernels bouncing out but putting the majority of the powder in the cup first the trickled kernels tend to stay in the cup. Redneck I know but it works well.

If it works is all that matters. Good solution.
 
I recently bought this scale and so far it has worked just fine for me.

I have a M1000 scale also and didnt like it. I mainly use my Redding #2 which is my favorite beam scale.

Oddly enough, the most sensitive beam scale I've used is the Lee safety scale. It has no way to level itself but works down to 1/20 gr. The vernier scale takes some getting used to. Some call it a perpetual motion machine.
 
The FX 120’s other big advantage is that it is the base for the Auto trickler and super trickler, so if you plan to upgrade eventually to an automated system, half the pain has been had already.

What is the display resolution when displaying grains?
 
.2 decimal places in grains. Only had time to use it twice so far. It has worked well for me. The website has all the info on it. You can call them also, very helpful
 
So precision wise it fits my earlier post on the EJ. Same class. I like the fact that it has a the Auto-Zero function. It is an excellent feature. Just don't try and trickle powder from zero or it will go crazy thing that a few grain are a zero drift.
 
The A&D EJ54-52 has a high range (1mg resolution) and a low range 0.1mg resolution.
Has various menu functions such as Autozero modes and the ability to Calibrate at a user value.
I Calibrate at 10 grams on the low range.
Shop around.

Just curious, do you use the Auto-Zero? Also, what reolution(s) do you have in gn mode?
 
I typically turn AutoZero OFF.
On LOW range with 0.1mg resolution, 0.005 grain.
I found, on mine, Linearity is within one count when calibrated @ 10 Grams.
Checked with VERY GOOD check weights.
