All mine live in the airing cuboard but that just because its the only place I have room .

I dont think it make much difference , they just do not want to be left anywhere cold and damp , by the time you have got to a shoot they will have changed tempreture anyway.

In one of his pigeon vids G Digweed warmed his cartridges to (he believes) get a slight range advantage and he shows how warm cartridges leave less unburnt powder residue in the barrels.
Not sure myself but GD has tried most things and successfully.

well,

 

1, warm cartridges are different from cold. they burn cleaner.

2, i`d also try to convince people to store shells properly, too high a humidity, the powder can be affected... too cold the powder can be affected.....

both together can cause bad loads.

Simple answer is yes it certainly works.

 

The more detailed answer is:

The crimp on a cartridge is not sealed, therefore air can penetrate the seal.

Air contains water vapor.

Water vapor condenses with cold, lead shot acts as a heat sink thus aiding the process.

Water soaks into the wad and propellant.

Propellants are usually hydroscopic, thus they absorb the water.

The micro pores are there to aid combustion of the fuel.

If the propellant can't burn properly you will get much less bang for your buck.

Sounds logical to me

I keep a hand warmer in my cartridge bag in the cold damp days.

It does make a difference.

The mess in the barrels is telling you so, the propellant does not burn so well when cold and possibly damp thereby making for a less crisp/sharp report when fired.

i have a couple of the thermo clicky type hand warmers that i drop in my cartridge pockets when its raining. keeps the cartridges lovely and toasty.

 

it certainly results in a cleaner burn, especially noticeable in the semi auto.

 

mine are stored in a cupboard with a rad in it so its always warm in there.
