Even the most cheapest micrometer should the ability to measure both inside and outside diameter.

A OD micrometer can not measure ID, calipers will get you close but not exact.

OK, in my haste I mis-spoke.

Most calipers will measure it. Basic micrometers will not.


But it will tell you what you need to know a lot better than, "my bullet seats too low after resizing".

I have a few Harbor freight digital 6" calipers I paid $10 each. I may modify one to measure ID more accurately but this will take some time.

You can always order a cheap set of telescopic gauges online. They are very handy to a reloader, IMO. I have a nice set, along with mic's and calipers from my days as a mechanic. You dont have to spend big bucks to be exact enough for this use though.

I ordered mine from MidwayUSA a long, long time ago. They come in very handy, in all sorts of HoMo jobs.

Thanks to everyone for your replys. I measured the inside of the Die with my digital calipers and came up with .372 does this seem normal? tonight after work I will try some different brass and see what happends if the Die is ok I will try my 9mm Die as suggested to get a little more neck tension for my R-P brass.
