I load both LP and SP brass. All I do is keep them separate, and use a red marker on the case bottoms before I go to the range, so I can easily separate them later. No problems.

By the way, I haven't noticed any significant difference in velocity in the samples I shot over my chrony.

And to USMCspeedy: I do see the SP advertised from time to time on various forums. Just post that you would trade for LP and you'll have all the SP brass you can possibly use.
