Thread: A couple of new toys comp seating die and Comparator for Measuring sholder bump etc

Have you got something of a known length that you can measure 10 times with your calipers?

I wondered if my calipers were throwing an error but before I checked them out I got an engineer mate to turn a 8mm rod to an exact length (2.800") which was checked on his fancy machine. My calipers were measuring exactly 2.800". So that saved me however many dollars and I went elsewhere to look for the problem.

However maybe you just want a new pair of calipers anyway!

If I can find that piece of rod I can mail it to you if you like. Should probably try and find it first before I offer stuff...
