I would think the 3031 in cold weather is not good on temp scale for being consistent. I think thats one of the reasons the fast to medium powders work better.
Have you tried duplexing it?I’ve used IMR3031 in my .40 SML & it runs fairly even with 4895. Very tall powder columns & the 3031 is on the dirty side, but nuthin like Acc2495 is. That stuff was terribly dirty to where I only got about 6 shots before I couldn’t get another bullet down my bore without a hammer.

No, I have not seen the need to duplex any powder for my .40. I have duplexed powders but in my .45's.Have you tried duplexing it?
