Hey guys, is Remington .38 Spl ammo dirtier than some other brands, like Prvi Partizan and PMC in the same caliber? I recently bought 5 or 6 boxes of Remington and took it to the range twice so far. It seems that after shooting 50 rounds or Remington my revolver is more dirty than after shooting 100-150 rounds of the other brands mentioned above. Is it me, or is it true?
