The Hornady will most likely be a Chinaman. I also have a Chinese digital calliper and it works perfectly OK. It's the one I tend to let lay on the bench amongst other stuff.

My first Chinese calliper I sent back. It failed to measure repeatably. One test I gave it was to open the jaws to a random position, note the reading, zero the display, fully close the jaws and you should see the value you noted with a minus sign. My first Chinese callipers would fail this test roughly once every 5 times and would return a value not even close to the zeroed value.

I don't have personal experience with your Hornadys but they should be fine.

One issue I have heard of and I don't know what brand it was but the particular calliper ate batteries.


Back to your digital scale - have you checked them with a check weight. Use a light 22 cal projectile as a test weight and check each time before, during, after use. Keep that projectile aside. Or make a test weight out of something suitable close to your loading weight.

Great suggestion mate, I was just looking for check weights to buy, but actually having a projectile would be good to use as a nice and cheap check weight. Cheers!
