I recently plugged in the following specs into the Alliant reloading program: Green Dot, 12 gauge Rem Hulls, 1&1/8th oz load, Rem 209's and Figure 8. The PSI values are obviously inconsistent and, to me, raise the question of the validity of any of them. I sent them an e-mail, but they seldom, if ever reply to matters such as these. I guess PSI accuracy isn't important to this powder manufacturer just as long as it isn't dramatically understated so as to be dangerous? Seems quite sloppy to me. Certainly not very professional. Love their powders, though.
