Yep, I think Federal also has some small primer .45ACP too. I sort mine while sizing and de-capping. Large go in a tub ready for priming and smalls go in a cartridge holder. When I get 100 smalls I switch over and prime them. Then switch back to large prior to charging.
As others have said, flare just enough for the bullet to sit in the case opening. Not too much as it can set the bullet too deep.
