There are two schools of thought on that. One says fine, leave them loaded. So I tested that theory with two different rifles this modern rifle season.. an inline and a traditional. I loaded them took them out hunting, and then stored them in the wood shed which is not heated. I tried them yesterday. The inline did fire and I expected it to. It was a Knight Disc Rifle and seals up pretty good. The Traditional was a Renegade. The cap popped and it DID NOT FIRE. I then put a second #11 cap on and it fired.

The rifle I depended on to hunt with was unloaded every night, cleaned and reloaded in the morning for the next day. I never had a problem with that... so you be the judge. You can guess what would have been said had the only deer I seen during season came through with that traditional rifle that popped but did not fire. I will say that on the second cap, it fired fine and the accuracy was fine....
