you can play in -5 by warming them with your hands but you do run into the issue that if its left in the gun while your running and such for too long you need to take it out nd warm with your hand. from my usage I usually had about 2 mag fills if I kept it warm and during summer I can get 4. Not very scientific but for what its worth. Also I have teied in -10 to -15 weather and even after warming it cools so quickly in the gun that sometimes when you go to shoot it just comes out sluggish and 2 shots later your out. I'd say stick to spring, summer and fall.
