I bought a box of these to try in my S&W 629s. Based on the other 300gr lead data I’ve found, If I seat it to book COL it won’t fit in my gun. It has two crimp grooves.
I’m afraid if I seat it to fit the pressures will be too high.

That looks a lot like a NOE mold to me. https://noebulletmolds.com/site/shop...avity-gc-brass
According to Matt's description, 900-1000 fps is the sweet spot. You will easily be able to get that velocity unless your barrel is very short. This would be a perfect job for bluedot powder, although 2400 would probably work just as well. My guess is starting loads of H110 will be over 1000 fps.
