I'm gonna give you an answer but, you'll probably be mad at me when I'm done: Accurate manual says 72.0==58,300 psi with a 180 sierra boat tail. Speer says 75.0 is a max load with 180 gs. Lyman manual says 75.5 grains with an unnamed 180 bullet = 51,400 psi. Barnes says 72.5 is a max with the uncoated 180 grainers. NOW--aren't you glad you asked!!!!??? I'd say start at 72.0 and work up but that would just be my personal strategy--yours may vary!! | |||
