I have the Hornady lock and load powder measure and the Hornady bench scale. Lets say im going for 4.3 I get in dialed in but it seems to be either 4.2 4.3 or 4.4. im just starting out in reloading and figured the powder measure would be the same every time. Am i being to picky, should i just go ahead and use the ones the are a little bit off
