10mm LPP brass

I recently got a couple of hundred new Fiocchi cases from Diamond K. https://www.diamondkbrass.com/10MM-AUTO.html

Ammoseek turned up a few:

https://ammunitionplanet.com/product/10mm-new-brass-casings-starline-100/

I have not done business with either of them.

I have used 10mm starline brass, which has a LPP. It's great quality. You can find it available at various retailers. For instance, Powder valley has them in stock for $23 per 100: https://www.powdervalleyinc.com/product/starline-10mm-brass-100/

I buy direct from Starline, but also I have bought large lot from capital cartridge and I got about 70 small primer from the first 750 I deprimed

I have never seen anything but LPP 10mm. SPP makes more sense......if you can find any spp.

Blazer brass is SPP

Precisionbrass.net has 10mm brass sorted by primer size. The website shows large primer brass in stock with small primer available on request. I've ordered from them twice now and have been happy both times. Recently received 400 10mm cases and while I have not yet processed it I grabbed several handfuls out and did not find a single small primer.

Yeah I have bought 10mm from capital cartridge recently. Good price but about 30% was SPP. I am gonna run some tests in the next few days to see if SPP has any effect on my favorite 10mm load. From what I've read it should be next to nil. But we shall see.
