CCI #41 "EX" Small Rifle Primers

[MJC]

Looks like someone bought them already from Miwall.
Noticed that Miwall and MASS AMMO advertises CCI #41 "EX" primers. What does EX mean? Also has different packaging. Instead of 5000 they have 5292 count. OEM? Btw, mass ammo looks like a scam site to me.
Ok. I'm only hearing crickets.....

Old thread resurrection-
The 5292 count #41 primers are in different packaging than the std 5000 count cases. All #41 have an "EX" in the numbers on the box. 5292 count has a smaller case size, 18 flats and each flat has 294 primers with red foil instead of the yellow in some other #41s. Otherwise they seem to be the same and Miwall is legit and good to go.
