| Hey guys I am testing my new digital scale. It was like 50 bucks at a LGS. Any body have a weight for PMC Bronze 223 brass. My scale is saying 95.1 to 95.5 with an old primer still in the case. |

Quoted:
Oh I was comparing weights of cases. I already calibrated my scale with the 50 g weight it came with. Do you guys trust those digital scales? It just seems like when the batteries get low or something it might not be so accurate. I don't trust mine for weighing powder anymore, especially pistol charges. I just use it for weighing cases and bullets. A beam scale is just as fast for what I use it for. |

As the others said, there's a lot of variability with cases. I find bullets are decently consistent. Weigh ten of them and divide by ten. You should be very close.
If you haven't heard the advice about letting electronic scales warm up, you should turn it on and leave it alone for about 20 minutes before you use it. |

It just seems like when the batteries get low or something it might not be so accurate. They don't weigh according to battery voltage. They use a load cell that varies it's resistance according to the weight applied. They are as good as the load cell installed. This is why you would try to buy a known quality scale if you will be needing precision and longevity from it. Also they are EXTREMELY SENSITIVE to shock. Drop it or drop something on the scale table and it's done..... |

Different runs of brass from the same company can vary quite a bit, so what yours weight could have no relationship to what mine weigh. From my weighing of various 223 brass with primers, it seems weights tend to run between 90 and 100gr, but they certainly can vary beyond that range.
Re: electronic scale reliability, my experience with inexpensive scales has been so-so at best and pretty negative if the scale must be run off batteries. On the other hand, I bought a Dillon digital several years ago and have been very satisfied with that product-fairly sturdy, reliable, and consistent. My basic view on beam or digital scales is that you get what you pay for. |

I compared my Frankford DS750 to my RCBS 510 this weekend. One throw of Bullseye was reading 3.4gn on the digital, and 3.45 on the RCBS. 10 throws registered 34.1gn on the digital, and 34.6 on the 510. I trust the results my 510 gives me more than the DS750. I wouldn't think the digital would be .5 gr off with a 34 grain weight unless it is a really crappy one. The disadvantage to digital reloading scales is that the readings are +/- 0.05 grain but a better scale like the Gempro 250 or even the A&D FX120 are +/- 0.01 gr |
