I'm VERY new to casting - just started thinking getting into it TODAY. (I ordered some bullets from Beartooth three weeks ago, been emailing them about my order status with no replies, so I'll make them myself!!!).

Looking for a good source of:
.417 or .4175 bullet mould for 350gr. or so weight bullets
.416 gas checks
.512 mould for 600-700gr. weight bullets
.510 gas checks

Thanks,
Art
