The eighty-buck Cabela's scale caught my eye too. A well-built package. I picked one up (2 hour trip to Wheeling's Cabela's) and took it home (2 hours back).
After setting it up and calibrating it, I compared weights with my 5-0-5 and it was right on. I let it set a few hours and tried again. All was well and it didn't seem to drift.
I decided to use it to load some rounds with Unique. I got out a Lee dipper, dumped a scoop on the scale and the reading settled quickly. I needed to trickle a bit more to get up to weight. I slowly dropped flakes into the pan and the reading never changed!
The dang thing re-zeros itself or something when minor weight changes are made. It does NOT handle trickling powder at all. As long as I did it really slowly, I could've sat there and put the whole pound can of Unique into the pan with no indication of weight change.
I took it back to Cabela's (four more travel hours).
If all you want to do is measure bullet weights or something like that, have at it. It'll do the job. But if you want to use it as a powder scale (as advertised), forget it.
The Cabela's trip wasn't wasted though - I picked up a new S&W 438 and some ammo I wasn't able to find anywhere else, some primers and a can of powder. Heck of a Philly Cheese Steak sandwich at their restaurant for lunch too. I like that place...
