There are several things that may have cused your problem... My White has been loaded since Oct 9 and i would be the bank it will go off.
Did you fire a couple of caps/primers off before you loaded the gun to clear the flash chanel? Was it a fowled bore or a bore that had been cleaned - better way to put that question had the gun been fired since it was cleaned last?
I beleive the biggest problem arises when you bring a really cold gun from outside to a warm inside. I have never had a problem going the other way.
Cayugad and i did some experimenting with this problem last winter, can not remember the title of the thread but if you would like to see the results let me know and i will look it up...
Hope you get it figured out...
