Patch lube for cold weather

[Black Hand]

The patch heats up fast enough to not be a safety issue at all.
But a frozen patch/patch lube may create an accuracy issue.
Without some testing there may be a degree of uncertainty as to the results of shooting from a clean and extemely cold barrel.

BP ignites at ~800F and burns at a much higher temperature (as high as ~1500F). The chance of anything remaining frozen is extremely slim...
