having recently acquired a GP100, i have a mind to build some 357mag loads with 180gr bullets. there is no special purpose here other than just learning. i am looking at speer's #13 manual, which of course touts speer bullets, but i was thinking of hardcast lead (which i have never used before).
who would make 180gr hardcast lead for 357mag?
as to powders i would start with bluedot (my on-hand 'slow powder' of choice) then maybe AA#9 (which i have used in 357sig) or H110 (which i have used for 357mag 158gr). i would probably start at or below what speer #13 recommends for these powders, watch the speeds and watch the primers and cases.
might be a good idea to use the cases just once for this.
