First off I like my model T.
Second I trust it.
But I guess if your lab testing prooves otherwise to you then you have your trusted meathod, & I have mine, although I have no $10,000 scale to check it against, or even a lab or lab coat. I'm not knocking anyone's equipment. I never started down that road. I have asked many trusted shooters & reloaders on this forum about digitals. Many like them, & many you couldn't give one to. I don't belive my bank account would not allow me to play with your caliber of toys, so I got what is generally considered the trusted go to scale for accuracy & affordability.
But hey, that's just me. If 1 1/2 grains with his particular scale doesn't make a guy sceptical, go ahead on er'. I was just concerned for the guys safety.
As far as the flea market goes... Wow man. Who Peed in your cheerios today? That's low.
Tricky, your almost as opinionated as I am, haha. So how do I find info on these Ohaus scales? What price range are they in? Ill admit I do like my 505 scale, but having another trustworthy scale around keeps em all honest.
