Had a question that I wanted to throw around. I had heard from a buddy of mine that Hodgson Retumbo powder dosent perform in extreame cold conditions as well as in warmer weather. Has any body else heard this or is this the first? I use the heck out of this powder in my .300 RUM, never had a problem with it but I guess I havent tested it in extreame cold. Around 0 degrees F. is the coldest that I've killed critters at, just wornding let me know what you guys have heard. thanks.
