I loaded up twenty of my .308 rounds in Hornady once fired cases.
The primers don't seat flush of below the base of the cartridge case unless i apply a ridiculous amount of pressure.
The brass is clean as a whistle, pockets clean, and Winchester primers go in flush no problem.

What are you using to seat the primer. Have you tried a different brand as well. Is that brass from factory ammo? Is the pocket crimped

Brand new Nosler Brass. No crimp. Never fired.
Used a RCBS Rock Chuck Supreme and i had to really put some pressure on them.
Slightly easier if I use my Dillon 550 to seat them but still very tight.
Winchester primers go in much easier.
Winchester primers go into the Lapua cases like butter.
9-1/2's go into Lapua cases like butter but take extra force to get them below flush with the case head.
It's almost like the 9-1/2 primers are too thick by several thousanths.

Maybe once fired they will go easier. I know the relationship with the case head does change very slightly.

Your first post said Hornady. I would measure them to see how out of compliance they are. Most likely out of spec. Can't think of anything else.

Yes the first try was some once fired Hornady cases.
If primers weren't made of gold now I would just not use them.
better days are coming.
Maybe they will come down under 100 bucks a 1000 someday.

primer pocket swage time? Don't be afraid to swage that primer pocket, just because it isn't staked doesn't mean the pocket receives no benefit. A resize-size-check, kind-a-thang. Both brass and primers are too hard to get now-a-days so don't scrap em, resize em, can't do much about the primer diameter, so swage that pocket
