Question about reloading when it's cold

[Maddog 521]

Well I finished up the .45's today. It was 40 degrees when I started and 60 when I finished. It's warming up today and suppose to be close to 70 tomorrow. I wish that was all of the cold weather we'd have but I know January and February are coming.

In the military had to swin (with just wet suit) in 31 deg water for weeks during training. Yeah it was cold!

I like it cold, but that's too cold!

Thank you for your service!!

This is a bad idea. Any wet lube will just pick up grit. Take the priming bar out, smooth any rough edges with 600g paper, same with the slide area on the press. If you must lube it, use a dry graphite or moly, never oils or grease.

Sir,

I believe the gentleman said that he used dry lube -may want to check his post again.

Regards,
Andy

That's what I remember too.
What I forget is, was it 231/HP38 or WST, that when warmer, the pressure goes down? Cooler temps raise the pressure, against all logic.
I'm thinking that it was WST.

I did a test last summer with WST. I had 5rds at air temp, about 80, then 5rd kept on ice in a cooler, about 40, then left 5rds in the direct sun sitting on blacktop. An oven therm, stuck inside a brass rifle case told me about 120. Fired over the chrono, the 120deg temp load showed the 25fps lower vel than the 40deg load.
