dad used to send all his to Komp industrial welding supply and they would check their accuracy. I use his tools when I am reloading but I really dont need the degree of accuracy they offer. His mic will go down to .00000 but personally a good caliper is all I need
caliper vs micrometer
I have a dial caliper that I use to measure OAL on my reloads.
Sometimes it seems that a micrometer would be handly when I want to measure bullet diameter or maybe the case mouth diameter when I 'm setting the case mouth expander die....yet the dial caliper will sorta do this as well...I guess its a matter of accuracy.
Which brings up another subject...what do you use to "calibrate" your calipers with guess a gauge block is in order here.

Guess there is no end to the "toys" a reloader must have!

msredneck is correct. but the cheap 20 dollar calipers you pick up at auto zone you just close the jaws and zero the dial and you can get in a good ball park..My tools are Starrett which are alot higher degree of precision. just think 1/1000 of a inch could be the difference in a perfect fit and to tight... This is gonna sound funky but we ruined the accuarcy of a 200 dollar caliper because a summer helper stored it upright instead of lying flat for four months during the summer which caused a very very very slight bow.. =( talk about sensitve
Your current calipers wont give you those measurements?
= ( calipers are good for measureing the length of any object it can get its jaws own. I honestly dont use my mic that often, only to verify what my caliper tells me... As far as why a reloader would want/need/desire a micrometer is beyond me. If my dad was not a engineer I would not have the one I use. The only way I would choose mic over calipers is if i was sorting out bullets for a 1000 yard match, top sniper contest, or shooting an apple off your friends head. I stand by my idea of a reloader does not need that level of acuraccy. If you were thinking about doing smith work then yea pic up a mic but as far as bullet work goes you dont need it. My 2 pennies
P.S a round object is a straight object if you think of it as a series of similar straight lines rotating on its mid-point every degree :thumbup:
