Soft lubes in hot temps
I have heard some concerns about using soft lubes in hot temps. The concerns being that the lube can melt and migrate into the case having a negative effect on powder. Anyway, I loaded up a dummy 45 colt round using my home cast (two groove lee mold) 258 grain PBSWC with NRA 50/50 for the lube. I then used a tubing cutter to cut the round in half. The half with the bullet I set out on the hood of my truck and let the sun beat down on it all day. By the end of the day I would scientifically I would say it was damn hot, you had to toss it form hand to hand to handle it. Anyway, there was just a tiny amount of lube that seemed to have migrated past the bullet. Anyway, for those that are interested I don’t think it’s a problem, at least with this load. Your results may vary.

Biggest problem I've encountered is with heavy-recoiling rounds. On a hot day the lube melts and significantly reduces neck-tension. This in turn leads to significant bullet pull. I've run into this using LLA tumble lubed bullets in a 329pd on a hot day.
Even the mighty Lee FCD can't hold a slippery bullet alone. A word about crimping Last edited by totaldla; July 30, 2013 at 10:18 AM. |

Inside the car or metal ammo can will be hotter. See Chart at Midwayusa-different lubes - different melting temps. http://www.midwayusa.com/content/leg...ing_points.htm

In most cases I have my ammo stored in boxes with the noses pointed down. I have been using the 45/45/10 lube for almost everything up until recently when I started to play around with some Carnuba Red.
To date I haven't had anything not preform as it should, and I usually leave the ammo in the truck while we are in the country. In talking with Glen from White Label Lubes the CR should hold up pretty well to the heat, but most anything left in the heat too long has the potential to seep.
