What runout gauges do you guys reccomend for the 204. I guess i've about wore this runout topic out but it is something I was never taught to do and wasnt that important. thanx

I use an RCBS Case Master, but I wouldn't recommend it to anyone. It uses plastic V blocks which drag if your brass isn't squeaky clean. I have learned to live with it after a slight modification.

I would recommend the Sinclair concentricity gauge.

I've got the Sinclair and I like it. A well made tool. I have thier dial indicator. It is just fine also and a lot less expensive than the Mintoya.

I'll put in another vote for the Sinclair one. I just got the one with the digital fowler gauge. The only other gauge I've used is the RCBS case master and I prefer the Sinclair.

Try to find a indicator that reads in .0005 or even better .0001 . Much easier to read with more space between digits. Just a thought

Gently and sparingly rub a bar of soap on the plastic blocks.....your RCBS will be your friend again.

My opinion: The indicator has to read .0001.

broke: The other posters have steered you correctly in my humble opinion. I agree also that for best results, a readout in tenths is best.

Another brand of concentricity gauge that has not been discussed is the one offered by Darrell Holland of Holland's Shooting Supplies. It employes hardened steel blocks that have different holes in the base so that you can measure runout on different length cases or loaded rounds. The indicator that comes with it is shown below, but it only reads to .001". With practice, you can easily see .0005". I've got a Mitutoyo indicator that reads to .0001", but it is not shown in the photo.



Here's a closeup of the Holland unit:



The Sinclair is also a very good high quality gauge, and either would serve you well. You can always order the gauge without the indicator, and supplement it with a Sterrett, Brown & Sharp, Mitutoyo, etc. later. Most of the current offerings come with a General or Chinese indicator. I believe Sinclair offers a nice Mitutoyo unit on theirs. Very good stuff, and a needed piece of equipment for peak accuracy.
