If you want heat and oil-bleed resistance and still retain some cool-weather shootability you might to have to add some kind of metal soap to keep the oils and plasicizers tied up. BAC is good because there's not really any liquid in it in the first place, but it could benefit from some high-temp microwax to bump the high end and some of the cheapest, butteriest (not stringy), amber lithium chassis grease (not high temp disc brake bearing grease) that you can find to help the lube start flowing sooner in the cold. That will get you down to a little below freezing, but not much.
That said, for pistol ammo there is no beating powder coating for bomb-proof reliability and predictability in all temperatures, you just have to watch out for propellants that react with the coating snd soften it.
