I dont see anything to worry about either...comparing 38 special to 357 magnum primers is apple and oranges. 357 magnums are rated at much higher pressure. naturally the primers will flatten out more. If looking at 38 special, Take a look at factory rifle ammo as a comparison as well...some times i am quite shocked at how flat the primers get; 30/06, 308, 223 ect...much higher pressure...different platforms. Sometimes using a slower powder fixes flat primer issues. I have a 44 mag when i use what ought to be a farely light load with a fast powder i get sticky cases. When i switch to h110 no more sticky cases, even though the h110 load is much faster/louder/more recoil and muzzle flash.
