I use them interchangeably and have not suffered any problems. I can imagine that problems may be encountered if loading to the high side of the +P scale using mixed brass, especially after repeated firings. As the astute here have already mentioned, manufacturers do have different specs for their brass.

I have loaded .38 +P 158 grain RNL at 1,000 fps into mixed .38 and 38 +P casings several times over and have yet to see a detrimental effect or any sign that would indicate caution be exercised. These rounds are fired in either a S&W Model 66 .357 w/4" bbl or a Colt Trooper MKIII .357 4" bbl for proofing.
