A booster ignition circuit, similar in operation to an automotive ignition coil, pumps up the voltage from 9 to 150 volts. The EtronX computer is powered by a common 9-volt battery that also supplies the juice to ignite the primer.
The EtronX firing pin does not move but serves only to transmit the 150-volt pulse to the primer. The bolt on a conventional rifle compresses and cocks the spring that energizes the firing pin. The only difference between EtronX and standard percussive ammo is in the primer system.Īnother improvement on the EtronX is the shorter, lighter bolt throw. That's a 99 percent reduction compared to the standard 700's. Lock time for the electronic firing circuit is slashed to 27 microseconds. And, unlike mechanical triggers with friction and wear between moving parts, the EtronX with no moving parts gives you pulls that are smooth and consistent, with 36 percent less travel than the standard 700. Trigger pull is adjustable from a factory setting of 2.3 pounds down to a half-pound. So, in other words, this is the first machine with its brains in its butt. The trigger is basically a switch that sends a signal to the 8-bit computer tucked inside the synthetic stock. The key can be removed in either the On or Off position. The EtronX system is turned on and off by a removable key located in the grip cap. While heavier barrels tend to absorb more of these vibes than lighter barrels, this mild shake can still factor into bottom-line accuracy.
Short- and medium-distance target accuracy remains largely unaffected by lock time.Īnother drawback of percussion firing is the harmonic vibrations that the firing pin impact sets up in the barrel. As we mentioned, this applies primarily to long-distance shooting. All things being equal, shorter lock time reduces off-target barrel movement. A few milliseconds here or there may not seem like much, but when you're aiming and pulling the trigger, the muzzle tends to move around a bit. In a slower system, the trigger mechanically releases a hammer that pivots about an arm and reaches up to strike the firing pin, which in turn starts to move and then impacts the primer. A fast system typically consists of a trigger that pulls out from underneath a sear and releases a striker, or firing pin, which is driven forward by a mainspring.
The biggest variable here is in the trigger mechanism itself. In a percussion rifle, the normal lock time is anywhere from 2.8 milliseconds on the fast end up to or exceeding 7 or 8 External appearances aside, the inner workings of the new Model 700 EtronX are nothing short of revolutionary. A significant factor in this is lock time, or the interval between the instant the trigger releases the firing pin and the point of sufficient impact of the firing pin to detonate the primer. On the accuracy side of the equation, the longer it takes between the time you squeeze the trigger and the time the bullet exits the muzzle, the less your chances are for achieving a dead-accurate shot in long-distance shooting. In two more words-simplicity and reliability. What Remington has done is take the mechanical trigger and related hardware required to energize and release the firing pin of its standard Model 700 and replace it with an electronic trigger and an electronic, versus the usual percussive, ignition system. It's the opening salvo in what could well be the next revolution in firearms. Remington's new Model 700 EtronX centerfire target rifle and pesky varmint bagger is more than just another gun. External appearances aside, the inner workings of the new Model 700 EtronX are nothing short of revolutionary.Ĭonsider it a shot in the arm for factory sporting rifles.
