10mm with small primer pockets.

[CoalCrackerAl]

I loaded some 10mm. I got my large primers handy. Only to find most have small pockets. Federal H.S.

I have not seen small primer 10mm yet but it does not surprising either. Sort them into two piles and load them up.

I don't mind two primer sizes for a given caliber, such as 45ACP or 10mm. When the next shortage comes around you can have cases ready for whichever primers you can find.

 

[CoalCrackerAl]

I'll start checking when i find them. And put them in their own bin. I do the same with 45's too.

Small primers in 45ACp are evil.

This is half the reason I ream the primer pockets of any new range brass that comes home and into my collection (large reamer wont fit in small pocket). There is a corner where I put all the found small primer 45 & 10mm cases to sit and feel shame. I buy 8:1 LPP:SPP

Sounds like a progressive loader...

I’m glade they make 10mm and .45 in SPP & LPP

so, the reason for SPP 10 & 45. Ranges requested them, SPP are lead free, LPP are not

At first I thought 10mm SPP brass was a bad idea and passed on it. Now that primers are hard to come by, and since I have more SPP than LPP, I kinda think I missed an opportunity...

Same! in 2 years, I only bought 1 pack of LPP@ $52, and still don’t want to use them. SPP, got enough to not sweat so hard
