The Firing Line Forums - View Single Post - CCI 550 versus CCI 500 small pistol primers

iluvlabs1 · February 19, 2012, 07:56 AM

I have been reloading 38 Special for a few years for target shooting. I normally use 158 grain, .358 diameter SWC above 4.0 grains of Bullseye and a CCI 500 small pistol primer. The rounds are shot in either a S&W or Ruger .357magnum revolver. The loading manual data is based on use of a CCI 500 primer.

I was recently given an quantity of CCI 550 small pistol primers. The manual shows these for some .357 magnum rounds, but not for the 38 Special.

Should I be concerned, or does anyone see a safety issue, if I use these CCI 550's in lieu of the CCI 500's for reloading as described above?

Thanks.
