Setting bullet depth with RCBS Precision Mic?

Re: Setting bullet depth with RCBS Precision Mic?

Can it be used to measure the loaded cartrige and thereby setup up the seating die--absolutely.
Can it be used to seat the bullet in the loaded case--absolutely not.

You talking about this?

It is supposed to be able to be used to check length of ammo to lands but it never worked for me. Probably operator error but I just use a dummy round to do it so I have it for later also. I do like that tool to check how much I am setting back the shoulder when FL sizing.

They can be used to measure distance from the lands, but if your bolt has a plunger ejector, they work better if you remove it. Since you only need to get the measurement once, this is not a big deal.
