First off, thank you one and all.
Secondly, Dennis, my goodness, exactly the information I needed! Thank you!! No worries about more than I asked.
Things got a bit out of hand the last couple of days so I am no further along but it'll come back around in the next day or so. I suspect paper patching is in my future. For now, I have a small supply of jacketed and some pre-cast .366's. I can also see a mold in my future.
BTW, mine is not Nitro proofed so I will be filling the case with black. What are the implications of black with jacketed? Worth the effort or just skip it?
