Does anyone have experience with 975 grain cast bullets for the 50bmg or 510 whisper? CBE out of Australia makes the mold. I think this is simular to the ones "Ranger Rick" used to cast based on real old threads. I recently came onto a few hundred pounds of wheel weights and am interested in casting these and using them in my 510 whisper. Also throwing around the idea of powder coating them go keep my supressor clean. Thoughts?

Well I ordered a mold. Once I get to casting I will update with some results!
