this tool is great for checking neck wall thickness
Handy for confirming case neck dimension
Quick easy to use tool to confirm accuracy of neck turning tools. Accurate confirmation of neck thickness consistency.
Fine instrument. No documentation
I will use this to measure neck thickness as is most likely the case for everybody. Pros: Precision Engineering. Very high quality five stars without hesitation. Con: just one really. Mine did not come with a manual. Fortunately I already know how to use a Vernier scale so in my case didn't matter that much. The video doesn't show any of that.
Top 3 tool on bench
This is one of my best and most consistant reloading tools on my bench. It is much easier to use this Starret mic/tool as it applys the exact repeatable tension every time to .0001. It is also very fast to hold in one hand and then slip the neck between the anvils and turn the top mic knob until it clicks. You get the exact same tension each time. You won't go back to using a standard hand held mic for measuring neck walls.
Excellent Tool for Measuring Necks
Simple to use and repeatable, reliable accuracy! I had a previous case neck gauge that used pilot stops, but would not measure 6.5X47 Lapua brass effectively due to the mandrel size and the small flash holes for this cartridge. I sold the previous tool for this Sinclair model and glad I did. With the ability to measure .0001, this micrometer will reveal the consistency of your case necks, whether turned or un-turned. Can simply add small washers to the mandrel to measure the same point on each case neck if needed. 5 stars!!!
Starrett is a quality product but.......
This product uses a Starrett 463 micrometer which is very accurate and quality built. The one I received from Brownell's had a thimble that was made to read in reverse. In order to get neck thickness readings, I had to subtract the micrometer reading from .0250" Not the easiest way to read a micrometer. When contacted, Brownell promptly provided a return label. I think this had to be a one in a million error on Brownell's part. Starrett does make micrometers for reverse reading but they said it is a special product and they don't see a lot of them. If the thimble was the normally supplied type, I would like the design of this mode.
Good Tool
Good tool. Every thing you expect from Sinclair. Measured some new cases and it worked as one would expect. My only negative is the numbers are small on the mic making it hard for my old eyes to read. Would buy again due to ease of use.
Junk!!
This thing is junk. It was supposed to be pre set. It was off by .0005. That is not acceptable for a micrometer. It is extremely small. So small that I could not read the numbers without a magnifying glass. You can get a much better micrometer and a better stand for less cost. Shop around. I sent mine back. Brownells was great as far as the return!
