Ok, I bought a chargemaster a month ago and I got a gempro this week.
I wanted to test the charges of the lee perfect powder measure vs the chargemaster, weighting those on the gempro, which is considered a very accurate scale at this price point.
So here are the results, for a target weight of 42 grains.
Lee powder measure:
42.10
42.28 max
42.02
42.08
42.10
42.14
41.98
41.86 min
41.92
42.10
Chargemaster, set at 42, read 42.0 all 10 charges
42.02
41.98
41.94
42.00
42.00
41.94 min
41.96
41.96
42.00
42.14 max
Results: (only 10 charges, don't flame me, I just did a quick review).
Lee: .42 gn max difference
Chargemaster: .20gn max difference
So, we could say that the chargemaster is easier to "set" to the proper weight, and that you will have a weigh confirmation of every charge, but once properly adjusted, the lee powder measure is more accurate that I though.
I used the same "technique" every time. Up, down, tap tap finger. (If you do not use the same technique every time, you will get important weight variations). I always throw 2-3 charges before I start.
Also, we can say that the chargemaster scale is quite accurate. Some people say that you should remove the powder, and then place it back on the scale to catch overthrows. Maybe if I had done that, the scale would have caught the last overthrown charge. If it had done, the chargemaster would have been accurate to .08 for this test, which is quite good.
Overall, there are only a few kernels of powder between the charges.
Now, is that .4 or .2 variation going to make any difference on POI at 200 yards? No clue.
If you arent so freak, the chargemaster is good enough to +-.1, and if you want to spend more time weighting, the gempro is quite good to +-.02 I would say.
The lee powder measure works, but you might expect a bit of variation so stay under max loads I would say. (I have had variations of almost +-1 grain with 300 win mag 2 years ago)
No real conclusions, just reporting.
My plan now, for precision rifle, is to throw on the chargemaster .1 under, and trickle the rest on the gempro.
If you do not want to spend 400$ for a chargemaster, the lee measure .2 under and trickling on the gempro will probably do the same, as fast or faster, for 400$ less, eh.
