A: Hello again George! I just got the most definitive answer to your question I could have hoped for. From the manufacturer: "Tim Sundles, the owner of Buffalo Bore Ammo and the designer of our ammo, says that load’s pressure is in the 47,000 to 48,000 PSI range."

A: Thanks for reaching out Charles! Your 629 can fire hard cast bullets just fine. I do not recommend this ammo for your revolver, however. This is a +P+ load, not +P, and Buffalo Bore explicitly warns that S&W revolvers are not rated for such powerful ammunition. They say this ammo is only good for Ruger Red Hawk, Ruger Super Red Hawk (the Ruger Alaskan is a short barrel Super Redhawk), Ruger Super Blackhawk or Vaquero, Freedom Arms Model 83, Taurus Raging Bull All Steel Versions (no lightweight alloys), Colt Anaconda, Magnum Research BFR and Dan Wesson revolvers.
