I use those 2 interchangeably, mostly Win SP, for 9mm. Unless loaded near the top of +P, I use whatever small primer I can get. During a primer shortage, we could get all the SP magnum Win we wanted, and little else, but our chrono testing showed no statistical difference with SP and SP mag using our normal powder charges of HP38 or Titegroup at PF 140 and below. The only fellow here that could not use the mag primers interchangeably was loading major 9 with HS6 to power factor 170, which is NOT SAFE in normal 9mm guns (used in a custom pistol for USPSA OPEN).
