Unclenick thanks for the info. I used the publised data from my manual.
I can warn about Trail Boss, and plated HBWC in .38 spcl. I had two squibs using a max load which is a full case to the bullet. I switched to Bull's Eye and the results were good out of my 4 inch Mod 67-1.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
