In a Ruger SA with a 45ACP cylinder, no problems whatsoever.
In a Titanium Taurus, fuggedubaoudit.
In the steel Taruses or the S&W 625, I don't know. Texas Ammo loads stuff HOT, so these are a "worst case scenario" 45Super. I don't know enough about the metallurgy of a steel S&W or Taurus to know for sure.
