I think 27 grains of H110 would leave me bleeding from the ears, but it looks like that Sierra is for 45 ACP and will open up at lower speed. Might have to try it. I'm shooting a blackhawk but want to find that nonexistent perfect compromise between easy on my ears and the meat and splattering red paint. I've thought the XTP was a little tough but it did do more damage than the SWC.
