Primer pocket depth?

The Alpha 6BR variant brass offerings measure 0.120-0.121” using the Accuracy One pocket gauge made by CTK. The primer pocket depth consistency in Alpha is tighter than I’ve found in any brass I’ve tested.
 
Better yet, for precise crush without having to measure every primer:

this seems like a painfully long process and having to manually feed individual primers.

It's likely the fastest way to get each primer to an exact crush. I can do three a minute, then I am done. It took me more time when I seated to a depth from the base, then measured and sorted, then reseated the shallow ones.

However, as I think about this, I am going to stop explaining this. It is of no advantage to me if anyone else seats primers this way. fact, it's probably a disadvantage for my shooting competitions........ :cool:

Why would the brand of brass matter if he told us he uniforms to .120”?? Seems like the correct question might be what primers he is using, right??

Because Virgin pockets are typically .002 to .004 deeper than .120..it would be tough to uniform, something you can't uniform
