Okay guys. Trying out the estate sale RCBS 38-150-KT 2 cavity this morning. Previously soaked in evaporust overnight (very light rust mostly on the outside) then washed with hot water and dawn, then dried and set aside til now. Alloy is mostly coww and some soww added, from my previously made ingots. Thoroughly fluxed with sawdust prior to casting. Ladle pouring. Temps from 715 to 775, with better bullets coming from the higher temps. Took about 10 or 15 pours to get my first keeper. Now the questions: the far cavity cast pretty good, but the near cavity was consistently giving me bases rounded and not filled. Tried pressure pouring that cavity, and it helped, but not consistently. When it did fill, it had a frosted look on the base band. They weigh about 156 +/- 1. I ran a couple thru the sizer (.3575) and noticed the front band was not being sized like the rest of the bullet. These will be powder coated, then sized, so I think that will make up for that?. Any advise good or bad?
