A Mould Maker's Opinion for what it's Worth
Snaggdit, I work with Mould Equipment everyday, and I wish to urge you, in the strongest, and still be polite, be VERY careful of your sharp edges in the seams. From what you wrote, it would sound like you've done quite well as far as being careful, but please understand this, once the "iron" is removed from a sharp corner on the mould cavity? you're going to start getting fins in that exact area.
Also, please be careful of your bullet diameters, you might want to check them, and be sure they don't become oversized...
Sorry to sound rough, it's just that I want to stress taking very good care of the Moulds you have, they're precious, especially in todays political situations.I'm sorry, I know that this message sounds pushy and bossy, I genuinely don't mean it that way. It's just that I repair Mould Equipment for a living, and I have to replace the nicks, bumps, and scratches with by Gas Welding. It's a whole lot harder to put the cavity form back, than it is to damage it.
Take Care,
Jim

Cast pure lead boolits and used a cordless drill with a flattened finishing nail to spin them in the cavity with polishing compound. Smoked well, still sketchy dropping. I will try the Kroil next time I get to casting. Loading some 40 today, might use up my cast boolits and will have to cast some more. Time allowing we will see.
