Using the Berry's plated bullets
I got this from Bud Watson:
IMPORTANT: All of our standard caliber copper plated pistol bullets share only two limitations - which are : NO velocities over 1200 FPS and for revolver bullets - NO heavy roll crimps.
I find that Speer data for their copper plated (TMJ & GD-HP) bullets is often close - and a good starting point for our bullets, if you pay attention to the exact nose forms - which affect the OAL - which affects the pressures.
I use them for:
45ACP - 230gr.
.38+P - 158gr.
9MM - 147gr.
