I'm new to shotshell reloading as I've only loaded rifle and pistol. So how does PeteM's chart relate to Lead Units of Pressure? LUP is what is listed in an old Lyman Shotshell loading manual I have. I'm used to CUP (copper units of pressure) for rifle and pistol. After reading and re-reading the shotshell manual I'm about ready to forget shotshells and stick to what I know and do best.

Practice safe eating. Always use a condiment.
