I just started getting into casting for my 45 ACP and would like to start branching out into other calibers. One of the next I am looking into is the 300 Whisper and I have noticed that a lot of people are powder coating the lead to mimic a jacket and reduce leading. It got me to thinking about using powder coating to push lead in the 450 a little harder. I've read a lot of the lead bullet for 450 threads and it seems to have mixed results. The only mold I have for now is a .452 200gr SWC, but I thought a lead 230gr RN bullet would make a cheap plinking round if the powder coat allowed for a little faster velocity.
Has anyone experimented with powder coating bullets for the 450?
