Several years ago Remington was marketing a rifle that used a battery powered ignition system that fired with electronic primers but I haven't seen anything about them for quite a while. I think they were called Etronx or some such name as that. They just didn't go over with the consumer public. I never took them seriously, and apperantly I wasn't the only one. I stopped mid-post and did a search for these Rems and there seems to be a lot of info on the net about them, I am just not interested enough to read about them again. If I remember correctly the 22/250 Etronx was the only caliber Remington was loading factory ammo for but.....
