Rainy Day Casting

[KHornet]

For some reason, it seems to me that I cast better quality bullets on rainy days. Maybe it is humidity, who knows. However, we have had a couple of days where it rained for near 24 hours, and then off and on forthe next 24. I cast in my garage, unheated unless I have fired a kiln the night before. Very small percentage of rejects on all that I cast.

I cast about 3500 bullets in those two days, 125 lee FNRN 9mm, 130 gr Lee RN 9MM, Lyman 452488 200 gr.
429 200 Lee, 356120 TC Lee's, and Lyman 358477's. All of the molds ran like a dream, with emphasis of the
6 cav lees. Wish Lee would turn out a 6 cav that closely resembled the Lyman 358477. Wish sizing and lubing was as fast and easy.

Our late friend Felix Robbins often commented about the joy of casting in "condensing atmosphere". It's magic. Or ground-level ozone. Something to it for sure.

it's the moisture in the air.
it was one of the first conversations I ever had with Felix.
humidity allows the alloy to flow easier.
in the winter I build a fire in the shop and boil water on the stove.
in the summer I use a small swamp cooler to raise the moisture content in the air.

I have to try pretty dang hard to get anywhere near 50-55% unless it's right before a rain/snow storm.
probably why I have such an easy time powder coating.

Interesting... I've always cast on rainy days just because I couldn't go out and shoot. I've never thought about casting results based on moisture in the air. I will have to compare results between rainy days and sunny days.
