    I have a question regarding the caliper that I currently use for those that have a little more experience in using that tool. Prior to this, my experience with using a caliper was limited, so I am uncertain as to whether this is within the boundaries of acceptable. First off, the one that I have was included in a bundled kit purchased with press, dies, etc. It is a low end piece of equipment. My limited experience with reloading is primarily handgun caliber and I have recently started with 223 Rem. I have noticed a consistent variation of .003 when the cases are being measured at different points in the jaw (top, midway, bottom). Is this an acceptable variance or should I purchase a replacement? If not, do I then use the smallest measurement of the case as the "correct" length?

    Thank you in advance for any insight provided.

    Another way you may get variance is if your brass isn’t centered in the caliper, and putting it in, in different orientations. If the mouth of your brass isn’t square, one side higher than the other.
