It might be 36 gr mold any way it was like 120 bucks for the mold out of aluminum handles and shipped I didnt think it was to bad a price for .218 mold
I want to do the same thing . Cast some heavy slugs for .218...I'm thinking about a regular 22 condor 24inch tube..I have been casting and powder coating slugs in .510...First pcp .510 second will be 22 cal....I do things backwards.. Lol. Should be easier getting 22 cal pcp accurate than .510 Texan... Powder coating your slugs is pretty easy and well worth it on any lead slugs...Keep us posted on your results casting for .218
