Lee .600 roundball mold

[Ricochet]

I just got one in the mail and was eager to pour some. I had 20 or so .595 balls and shot a few bare and patched but wanted to try a little bigger ball without a patch to see if it shot any better than these. The .595 balls were a little loose. I got everything together and got pouring. I measured a few and they every one came out .594 to .595. I have a .575 lee mold so I got it ready and poured a few with the same lead. They came out ..575 or close. My .395 mold pours .395 and my .310 mold pours .311. Is my mold mis marked or do they have this margin of error? Did I just get lucky with my other 3 molds? I am scratching my head. I feel I got lucky when I found this mold with all of the no stock everywhere and just don't want to try and find another.

I do not have anything from Lee in front of me, but memory says their tolerance on roundball molds is +/-.003”.

I have some .575 balls that I will try with a patch. They load what seems to me with just the right pressure. I can push them in with my thumb. The .595's need a whopping to get em down, and then the trapped air will stop them from seating sometimes. Keeps me on edge and fidgety you know. This needs to be a stress reliever not a means toward a panic attack
