I saw this on Remington's website..it sounds awesome! It's a new firing technology. Unfortunately it's a little pricey, well it's a lot pricey. But, what a great concept, once they become more common the price will come down. If you want to check it out here's the link:

My wife's best friend's hubby works @ Remington's R & D dept. Maybe he can give me some info on field reliablity.
When I was in the army, some of our equipment used 9 volt batteries and it worked fine under some pretty extreme conditions. You just had to make sure you had some spares with you, especially when it was cold.
