never woulda thougth ! Slow down the press stroke....
Really like the HS gauge he uses. It's made by Forster the customer rep told me.

Precision Mic | RCBS

RCBS Precision Mics determine chamber headspace and bullet seat depth by measuring from the datum point on the case shoulder to the base of the case.

I'm getting one also.
Could get a little expensive as I have many different cases.

 

[milboltnut]

the RCBS doesn't check case length ?

Believe you 100%
We've been doing the double bump for years, you can use the first hold time count to wipe the lube off the previous brass, then the time count for the second round can be used to lube the next brass.

We use this process on everything from the small rifles to our large 416 stuff

Get a roller handle and it goes even more smoothly, plus you get a handle to lean on instead of a ball while you hold down:

Forster Co Ax roller lever. Standard height. - Inline Fabrication

Roller lever converts the Co-ax press to a super smooth roller set up. This lever is the same height as...

Or screw your die in an extra .002 and run fast?

doesn't matter.....from another forum

It's common to dwell at the end of stroke in metal forming operations and I find it helps me when sizing.

Magnum Mania said this on another thread months ago.
From now on I will do this on all my brass especially 300 Weatherby Mag that I had so much trouble with

 

[Taylorbok]

I haven't had a problem running the press relatively fast and only once. I can consistently bump shoulders back .002"

If what you are doing works well for you then I would not change a thing.
I had problems on 300 weatherby mag brass not being consistent and that's the one that ate my lunch.All others were consistently .002 bump.
MagnumMania said the radius on the weatherby brass is the culprit and to hold the bump for a few seconds and it will come around and it did!

 

[milboltnut]

the moral of the story? some need extra reinforcement then others.. kinda like raising children, some don't need as much as others. That may change when you get another lot of brass.

What are y'all measuring with? Something I've found changing from Hornady to Whidden to SAC comparators and stacking all of those up against an LE Wilson case gauge and mic is that there is at least a 0.001" of slop if not more in Hornady tools from how poorly the inserts are cut.

The LE Wilson (or RCBS/ Fulton style mentioned earlier) are IMO the most consistent because the body of the case is supported and they use a mic.

Not all brass is the same and different lots are different also. I buy at least 200 pcs at a time same lot- for hunting my tactical / bench / LR guns I get at least 500 of the same lot. Then weight them and gather in lots and mark them well, same for thickness- name of the game want them all the same or close as possible to the same, and keep the brass well marked.

I believe that's a Mo's gauge. Mo Defina in Ct. has been making these for decades. (I have about 6 of them).
