Got these two jigged, centered, and glued up tonight.

And onto their sacrificial bases.

Then into their molds.
I spray silicon release onto the bases before pouring to allow me to pry them off still when the cure is complete.
Then after pouring, Put them under 28" of vacuum for 5 minutes, then switch to 60 psi positive air pressure for a solid hour till they set up. Really quite pleased with the clarity this time since I skipped the sparkles. You can see the different rifling effect I put on each calibre slug even though the mold tubes.

Now 48 hrs to fully cure and I can turn them into their final shapes..
Still perfecting the zero leak sealing issues along the bottom of the molds. Luckily those stryations visible from the leakage during curing is all turned away during the final shaping.
Cheers gents.
