The saga continues...
First I had my own mold made. Iron block, single cavity 374 gr .452 cal. Boolits came out great, but the ogive did not work in the throat of my rifle so had to reject that.
Went ahead and ordered a 3 cavity, .452 400 grain aluminum block mold from Accurate Molds.
Let the mold warm up...tried casting at temps ranging from 770 all the way up to 900. Getting plenty good flow out the pot. Boolits came out wrinkly and looking like dog ****.
I'm thinking a 3 cavity mold may be to hard to keep up to operating temp with these heavy boolits. What else may be going on?
