45 ACP Starline +P Brass

This has probably been asked before, but is there any difference in how the Starline +P brass performs with our 45 lswc loads, compared to regular brass?  Can you mix and match, or does it shoot differently?

Thanks.

CORRECTION , PER STARLINE THE 45ACP+P BRASS IS THE ONLY ONE THAT IS DIFFERENT. BELOW IS FROM THEIR WEBPAGE.
"The 45 Auto+P is a strengthened version of the 45 Auto with the same external dimensions. A thicker web and heavier sidewall at base strengthens the case in potentially unsupported areas. This case has approximately 2 grains less internal water capacity than the standard 45 Auto."

As noted by JIMPGOV, the Starline 45 ACP +P brass has less capacity than their regular 45 ACP brass.  This will affect pressure and velocity.  See the article below for test results.
