Newer to 10mm but not to reloading. I'd like to stick to brass with large primers so I can save my small primers for 9mm and so different brass doesn't slow up my reloading process.
I just realized Remington UMC uses large but I had started to stock up a little factory (warms my soul to have a stash of factory even though I reload) American Eagle 10mm and they use small primers. 🤬
Other than AE, what other brands use small primers so I can attempt to avoid them?
Absolutely, having a stash of factory ammo is a comforting thing : )
Save the small primer brass for "field loads" where retrieval is not an option. We do this with both 10mm and .45ACP.
Any brass from the Vista Outdoors companies: Federal, Blazer, & Speer. Since Remington Ammunition was bought out of bankruptcy by Vista, it remains to be seen if Remington is converted to small primer. I have a 10mm revolver and moonclips are fussy with regard to brass, Starline and Federal work most foreign brass won't. My chronograph hasn't shown appreciable difference between primer sizes, but I suppose it is best to keep the brass segregated. I find that the operation of seating primers separates the cases: If you are seating large primers, they won't seat in Federal cases - case separated; if I am seating small primers, they won't seat in a Starline case - case separated. That way I'm not going through brass separating by headstamp.
It's interesting about the use of small primers for 10mm. For handloaders like us, it's an inconvenience.
Is it a cost thing??? Why are they doing this??
Cost.
Process cost, inventory costs, environmental costs.
Just looking at inventory costs for me as a handloader, I would be much better served if large primer pockets were reserved for only cases that with a volume over, say, 40-45 grains of water. The only cases I load for that really require a large primer are 30-06 and 300 win mag. I could cut small pistol magnum, large pistol and large pistol magnum from my stock.
The use of "Small Pistol" primers in cases the usually use "Large Primers" primers started out because of "NON TOXIC" NT primers that don't put lead vapors into the air for indoor ranges.
While many see this as a PIA for handloaders, it can be beneficial in times like these where primers are hard to come by in either size.

Agreed. With small primer pockets, one can always use Small Rifle Primers.
