Default Mitutoyo Tubing Mic

Like I said earlier I have a sinclair/starrett tubing mic table model that I am trading my smith for a mitutoyo hand held tubing mic, both 1/10 mics. Both do the same I like to have a mic in my hand. He has 2 so It's not a steal. He says the table model will be easier him to operate. Any feelings one way or another on tubing mic's. I have a full set of Mitutoyo Standards that I can check all my micrometers with.

The deeper the tubing mic can measure the closer to the jacket base you can measure. Look at the gauge used in the Hornady video from the 32 to 37 second mark http://www.youtube.com/watch?v=-EAyLUO3n1c

Notice the step in the Mitutoyo prevents you from measuring more than roughly 5/8" deep:


I haven't put my hands onto a set of the RCBS units but they might be more useful given the deepth but it all depends on that taper?


Here is another example I've considered and I'm sure there would be an equivalent in the US - http://www.measumax.com/10-130 the deisgn is useful but the accuracy let's the unit down.

So it's not long before you're looking at http://www.bullettipping.com/product...citygauge.html

and then thinking 'Should I fork out for one of these and still have to modify the right-hand gauge to work?':

Got one similar to the bullettipping unit you show that Bruno sells. His uses a .0005 gauge. I do like that CDI system you are showing that looks to be the best possible way to measure a bullet. Got a link. Have all kinds of ways to measure cases. One my smith gave me made out hardwood can insert any gauge. Have a case jig made by Joe Wagner that some have copied. For use with .001 gauge like the RCBS case jig.

Check out Gauging Applications #2 at the bottom of the page...do you think we'd ever see one shipped to Australia under the current ITAR system
