If you want to reload, especially for any kind of precision shooting, then an accurate and reliable scale is necessary for your setup. Scientific lab scales are all well and good, but a purpose-built, reloading-focused scale that measures in grains will always be better.
The Creedmoor TRX-925 Precision Reloading Scale is one such scale with a claimed sensitivity of one-hundredth of a grain which is about ten times finer than what other, similarly-priced scales are capable of measuring.
We grabbed one to see if the TRX-925 lives up to its marketing materials and put it through its paces. As an avid reloader with delusions of grandeur when it comes to precision shooting, the TRX-925 should be exactly what I need to produce consistent ammo at home.
If it can actually deliver the goods. Let’s find out.
What’s in the Box
In addition to the scale, you’ll find several other goodies in the box. It comes with a precision-ground stage, an AC power adapter, a draft guard (very necessary on a scale this sensitive), three calibration weights in 2, 10, and 50-gram flavors, Creedmoor’s anti-static powder cup, and some helpful instructions.
Specs and Features of the TRX-925 Scale
Being a purpose-built electronic reloading scale for accurately and precisely weighing powder charges to ensure consistent loading, it utilizes a strain gauge. It can weigh charges or finished rounds up to 925 grains.
It measures at a precision of .01 grains, which is more than most reloaders need, but it’s nice to have. It’s especially nice for precision long-range and bench rest shooters who can really make use of the extra sensitivity over other scales.
The calibration/check weights are F1 grade, which is about as accurate as you can get without spending nearly as much for the weights as you do on the scale itself. Precision gauges and weights like that are pricey, as my fellow machinists will already know.
An F1 grade means the weights are 10x more accurate than the scale is capable of measuring, so it’s safe to say they’ll work for this application.
A grain measurement is generally better than the more typical gram measure because if your scale measures in grams but displays results in grains, then there’s some math going on in that conversion that can introduce rounding errors. Obviously, not great for accuracy.
The draft guard is a simple 5-sided plastic box with a hole in the lid for a powder dispenser. You’ll likely have to do some finagling to get your powder measure or trickler positioned just right. I’d like to see some smaller holes around the top and sides, but that’s a highly nitpicky complaint.
The powder cup is nice and light and has an anti-static coating to prevent accidental sparks, which are never great when dealing with gunpowder.
Set-Up and Calibration
First-time setup is simple, and it is recommended that you calibrate your scale each time you use it. The whole process takes a few minutes at most, and all you have to do is put the appropriate check weight on the scale when it asks for it, starting from the 2-gram weight and working upwards.
Make sure not to touch the weights with your bare hands, as the oils from your skin can actually be enough to throw off the calibration and give an incorrect reading. Wipe off any dust with a lint-free cloth as well. Yes, it is that sensitive.
Unlike many other scales that offer this kind of sensitivity, there’s no warm-up period either, so it’s ready to go as soon as you turn it on.
Confirming Accuracy and Precision
Of course, sensitivity isn’t the same as accuracy, as anyone who’s visited a Facebook comments section can readily verify.
To confirm the scale was giving accurate readings, I measured the weights again and got the correct readings for all three, then measured a powder charge of a known weight from one of my previously assembled handloads.
My 37-grain charge of IMR 4895 weighed in at 37 grains, +/-.02 grains, over the course of five measurements with a measurement of a random check weight in between each attempt.
The highest result I got was 37.01 grains, and I got 36.99 grains one time. Verifying with the 10-gram weight, I got readings between 10.001 and 10.003.
Who’s It For?
Does that additional accuracy matter? It may not unless you’re competing at a very high level or demanding remarkably consistent performance. Most hunters won’t notice much of a difference, for example.
In my opinion, I think PRS competitors, bench rest shooters, and other folks loading up serious long-range cartridges that need hyper-consistent rimfire loads will benefit the most from this scale.
That said, this scale is ten times more accurate than just about every other scale I’ve found in this price range. Maybe I’m not a good enough shot to see a difference, and maybe you aren’t, either.
But I drive a truck that often has an empty bed, carry a $250 knife mainly for opening boxes, and carry a gun that I earnestly hope I never have to draw unless I’m at the range.
I believe it’s better to have it and not need it than to need it and not have it. And when it comes to this scale, whether you can take advantage of the additional precision or not, I think it’s better to have it.
If nothing else, it’ll give you more confidence in your hand loads and won’t cost any more than a comparable scale that won’t be nearly as accurate.
Final Thoughts on the TRX-925 Reloading Scale
If you’re a precision reloader or aspire to be one, then the TRX-925 is a worthy addition to your setup and deserves some serious consideration. It has everything you need at a price that puts an entire industry segment on notice.
It’s dead simple to use, sets up in minutes, and measures with a level of precision and accuracy that is hard to find at this price point. It also measures in grains (though it can display results in grams if you want), making it a true reloading scale rather than a traditional lab scale.
I’ve been nothing but impressed with it, and while I’ll update this review if anything changes, I fully expect to be using it for years to come.
