I have to agree with Smokey Joe, it was a solution in search of a problem. I can see the application in a pure target gun, where trigger let off is a major factor in accuracy, but not in a hunting rifle. I think Remington at that time was anticipating laws on "personalized" guns, and an electric mechanism would lend itself to use of a password or fingerprint check easier than a conventional system. They seem to have backed off that period and now have made a decision to help fight proposed gun laws, rather than accommodating them. (Witness their reaction to Zumbo's "terrorist guns" blog article.)
High Standard made a pistol with an electric trigger at one time. It used a solenoid to release the sear, but the .22 LR ammunition was conventional.
