Alpha Dasher Brass Primer Pockets/Seating?

OK, I've read all the old threads I could find on this but I'm looking for the latest info. Is this still a concern? Thanks for any info. PM is fine if you prefer.
 
Does it take excessive/abnormal force to seat CCI 450 primers into new Alpha 6 Dasher brass? Thanks for any feedback
If I remember correctly, on the new brass, it was a pretty good chore to seat the primer using my Lee hand held. I may have finished the job using my RCBS bench mounted seater. After a couple of firings, the Lee does the job just fine.
 
I have used both Fed GM205M and CCI 450 primers in new 6 mm Dasher Alpha Brass with no issues using a hand priming tool. Part of my initial brass prep process, however, is to uniform all of the primer pockets with a K&M primer pocket uniforming tool. It did appear that the primer pockets were a bit snug when I was uniforming them. I have not tried seating a primer without uniforming the primer pocket.
