I am in the process of building a 458 lott. I plan on using mostly 458 win mag brass, but wanted the option of shooting the longer case too.
I have an excess of 300 H&H, 375 H&H, and 300 WBY brass, what would be the process for blowing this out to 458 lott? I recall hearing of cornmeal and bullseye, but don't know the proportions. Do I need to anneal the cases first?
