most scales and measurers are made in China, but a Pact isn't. I own three different Pacts right now, and have had a fourth in the past. Now I'm just getting ready to start with an electronic measurer, and it will be American made.
Check weights are a joke! I've checked a lot of them on lab scales, and never found one that was all that close. I've seen then out by as much as seven grains, but have seen them as close as one and one half grains. You can buy certified check weights, but they are expensive.
electronic measurers are great as long as your only using one powder type. When you switch powders you gotta clean the thing out, and that RCBS don't clean easy (Chinamen don't clean much of anything anyway). The Lyman and Hornaday are no better as well, but the RCBS is better (not by much). They also seem to be prone to problems with fine grained powders, but that's not a problem for me as my Harrell will throw that stuff within a tenth of a grain all day long (My Lyman #55 is far off that mark either). I happen to use a dozen different types of powder, so that's kinda importat to me.
a word on reviewers: Pay zero attention to them! They don't give a good review, and they don't get another freebe from jakes reloading outfit. Every month somebody comes out with a new item that will be the saviour of the planet. We all run out an buy it only to see little if any benifits (they got me a few times). My all time favorite is the Redding bullet seater that was supposed to save the planet. It turned out tobe no better than the design they stole in the first place (Forster), but was 50% higher in price. So much for making a profit! If you simply loading revolver and pistol ammo, then buy a good thrower and be done with it. But if you doing very long grained powders (4350 and up), you might want to seriously invest in a good measurer.
