The Lee Cast Bullet Handbook is a resource I turn to frequently. I also use my chronograph frequently. We all should know that lubed lead, polymer coated, plated and jacketed bullets produce very different pressures as well as velocities when loaded with the same powders. Is there too much variation to make a manual practical? Do "Blue Bullets" or Bayou behave differently than my home-cast ones coated with Smoke's powders? Will the new book point us toward powders that work better with PC'd tips? Don't get me wrong, I enjoy developing new loads and experimenting. It's just that I believe many folks could benefit from a little guidance on this subject. Thoughts?
