Question about weighing brass and bullets

[M-Tecs]

You asked about a scale that reads out to 1/100th of a grain. I provided images of the scale I use that reads out to .01 grain, which is 1/100th of a grain. Beyond that I have no interest in debating the issue further.

No, the images your provided show .02 of a grain which is 1/50 of a grain (153.94, 252.92 and 161.18). I did am image search and located one that looks exactly like the one you pictured.

Its 0.001 grams which is +/- 0.01543235835 grains on the display which is why it reads in 0.02 increments. The displayed verse actual weights is the real question.

I have not tested this particular scale but at $18.69 I just ordered one out of curiosity. We'll see how it does with actual calibration weights? Others of this type have not tested well.

This has been my go-to scale for about a dozen years. https://www.accurateshooter.com/gear...-mxx-123-test/ It tests out very well but it's also a 0.02 grain.

Normally to get a true 0.01 grain scale you need to spend about a grand.

I am also considering this one. https://www.creedmoorsports.com/prod...&cid=aff_53743

Introducing the TRX-925 precision digital reloading scale by Creedmoor Sports. Our development team set out to create one of the most accurate and precise scales on the market that directly meet the needs of reloaders who are looking for the pinnacle of performance. To achieve this level of precision and accuracy, the team focused on the needs of reloaders first and foremost, and worked to develop a high-performance scale that aims to be the premier reloading scale on the market.

Our specialized programming of the TRX-925 sets the Creedmoor Sports TRX-925 apart from other scales in the market. While measuring in grains may seem like the norm, the vast majority of scales on the market utilize grams as their native unit of measure and simply convert the measured weight from grams to grains by using a formula. Unfortunately, this method of behind-the-scenes conversion generates significant rounding errors that can affect the reported weight. With the ability of the TRX-925 to read down to 0.01 grains, eliminating the gram/grain conversion process, making this scale the only reloading scale that offers true +/-.01 grain accuracy and measuring natively in grains was an absolute must to achieve the level of accuracy the Creedmoor Sports TRX-925 demonstrates.


Yes it reads down to 0.01 but the claimed accuracy is +/-.01 grain but it's about 1/3 the cost of scales that hold a total accuracy of 0.01 grain.

I stopped weighing brass. I do use brass purchased in one package.

My method is to track muzzle velocities. If a round is a bit high or low comparted to the rest then I mark it. If it falls out of the average again, I put it in the 'plinker' bin. As long as I can get 0.5MOA with jacketed and 1MOA with cast I am happy.

If I were a serious competitor in benchrest or long range precision I'd sort the brass by volume (size, trim and water weight).

Bullets for long range I weight sort to 0.1gn. For the Garand I only sort to 0.5gn (open sights just aren't that accurate for me anymore).
