Sir, when I was shooting NRA high power a lot, I bought one mainly because it was cheap and had a reputation for accuracy. The "cheap" part was correct, the "accuracy" part less so.
I found it to be inaccurate with stick-type rifle powders, specifically IMR 4895 and VV N540. It would vary by as much as half a grain from charge to charge, though usually less than that, say 0.2 to 0.3. It was closer with the Vhita Vouri, presumably because of the shorter "sticks," so I plan to try it with ball-type powder and see if that goes better. If not, I'll just pitch it--an inaccurate measure is worse than no measure at all.
Hope this helps, and Semper Fi.
