Metric primers?

Nor does it say they are metric. How do you know when you are buying metric primers.
They will have a country of origin. Anywhere other than the US, it's likely a metric primer. Best bet is, whatever brand you are planning to buy, drop a question or search for something like "do <someprimercompany> [small large] [pistol rifle] have problems seating?"

Once again: the standards are large/small, rifle/pistol, and shotshell/shotgun or other.

“Other” can be any ordinance which uses a primer but is not pistol, rifle or shotshell.

Metric (SI) and Imperial/SAE are systems of measurement and the system used has a measure for each dimension and a tolerance for each measurement. That is where the “metric v. standard” distinction applies.

Did you ever follow my advice and actually read the SAAMI standards?
 
Why don't y'all write them and ask if they are made to SAMMI SAE spec, or a metric spec because of the country of origin.?

Otherwise we are guessing since they come from overseas they are indeed metric, which may be true, dunno.
 
See @EricBu ……….
This is not a difficult thing to grasp in my opinion…..
Just forget anything was said and use them like ANY OTHER PRIMER…….
Exactly Soonerpesek ,,, I am now using all imported primers and they all work well do they seat slightly harder in some cartridges, yes they do but in older brass that is good where domestic primers seat to easy. Do some guns FTF with them yes they do, but I have guns that do it with domestic also, just seat them firmly use them and forget about all this other stuff.

I've got to agree but I'd still like to find out for myself.

Unfortunately, I have too many other tests and experiments going on otherwise I'd buy a sampling of all imported I could find and test with my pistols. (After uniforming and reaming and deburring and polishing the primer pockets of course.)
 
I'm getting ready to load some 9mm, using Fiocchi SP primers for the first time. I'm trying to decide whether to just fill up the primer tube or try out a few before I do that.

Fingers crossed. I'm pretty sure that I'll be OK.

I have not yet used the Fiocchi brand primers, but from what I have read and seen here—-sounds like many would recommend them highly….
I certainly think you are golden….. :thumbup:

The lots I’ve used ran to the low end of the tolerances on both height and diameter. Which would seem to substantiate the complaint about Fiocchi brass having tight primer pockets.

I have a brick of new-er production but haven’t tried them yet.

They're metric. It's on the box. 4,5/3-P1. The 4,5 is mm dimension for small primer pockets. 5,5 is large primer pockets. Certain European countries use comma instead of period.

Ginex themselves have specs for all their primers on their website.
If you want the specific dimension for that primer. It's 4.48mm (-0.05mm tolerance) diameter. Metric to Imperial conversion - 0.176378" (-0.001968504" tolerance). If you look at the SAAMI spec for primers, this is within SAAMI spec for diameter. The nominal spec for diameter is on the upper end of SAAMI spec but still within it.

OMG! Facts! And a link. And a picture.

Better delete quickly!

Just kidding of course—good post!
