I cast up some 300 grainers at the same time and at 700 to 750 they were shinny. I may try some more 300s today to see how they come out.
I did find out that I had to leave the 500s in the mold longer than usual before I dumped them out of the mold so they could have a little more time to harden up a bit. That may be due to the 850 temp.
I am all ways learning from the school of hard knocks. This is no different.
