Just purchased this tool form the USA distributor - Carl in Colorado, and it is very nice. Thanks all.

Very nice set, just received mine 😊 - shank on my iGage I already had was 9.5mm so had to open out the former a little

All the manuals and books I've read say to seat the primers firmly to the bottom of the primer pockets without crushing them. So, I do not worry about how far down the primers are. Nor do I worry how consistent the seating depth  is as case rim thickness and primer pocket depth  are what causes most of that and is immaterial to me so long as my primers are seated  firm to the bottom of each primer pocket without being crushed. That is to say I care more about the distance between the primer and bottom of the primer pocket, as opposed to the top of the primer and the surface of the rim of the case. The only concern I have with the top of the primer and the case rim surface is that the primers are below flush. If the primers are to far away from the firing pin I see that as a primer pocket issue not a primer seating depth one.

I do have the PCPS with micrometer, being it is the best out there in m y opinion to seat primers with, and I set it up to be able to crush primers yet I stop without crushing them by feel as all manuals recommend.

Accuracy One has been making these for years. And only uses one base that is steps to fit various cases.

i sent you an email about ordering one to the states

No effect on accuracy unless primer is gapped or crushed, there is 0.013 between the 2, pick your depth.

That's not crush depth...that's just how far below case head tr primers are seated..

Wish you made some adaptors for 9mm straight wall cartridges

I just bought the set on Amazon, but it does not come with a blue 3D print box like the one you got. Is there a place to get one?
Also, shouldn't the read out be a negative value not positive it is zeroed correctly?
Also, what case base do I use for 300 PRC- 308?

Will this work for small rifle primer pockets

measuring primer depth relative to the bottom of the case is pointless. the correct datum is the top of the case rim like the PCPS uses to set the primer to depth. if you changed the PDG to use THE SAME shell holder as the PCPS, then the primer depth measurement would be meaningful. and even after all that, the primer depth measurement tool is only a comparator. it will never be a gauge.

Hi, I have an igage depth micrometer and it is a 9.5mm.  Is there a way to make it work?
  I also have the pcps. I just ordered a support from a youtuber Hit the X reloads which allows it to not reference off of the rim and cut the variation of seating down to .0007 inches.
 Thanks, I enjoy your products, I've had the bullet comparator for quite awhile now also.
