Michael, excellent questions!
BroncoGlenn, my down range skills can always be improved, what about yours?
Here is some information I pulled off the SpeedLock website at
www.zediker.com. It addresses some of the issues you brought up.
The flight time of most bullets through the barrel is 1.0-1.5 milliseconds (thousandths of a second) while the lock time of most conventional bolt action rifles varies between 2.6 and 9.0 milliseconds. On average, a SpeedLock Systems alloy firing pin cuts lock time approximately 31 percent. Combined with a radically improved SpeedLock CS Spring (included), lock time is reduced another 8 percent. This is a total reduction in lock time of 39 percent.
The effect is amazing: by the time the firing pin has reached the primer on most rifles, the bullet has already left the muzzle on a SpeedLock Systems gun! Dry fire just once and you'll hear the difference!
The result is simple: a reduction in lock time will cause your rifle to hit closer to where you held the crosshairs when you pulled the trigger. Everyone's rifle is moving when it's fired. The amount of movement may be almost imperceptible, but that's all it takes. If you're shooting at a trophy deer at 300 yards, movement at the muzzle of only 0.058 inches means a missed animal. If you're a competitive silhouette shooter, just 0.022 movement makes the difference between a hit and a miss on a 500-meter ram. When lock time is reduced, the probability of the misses and lost points is reduced. SpeedLock Systems helps you squeeze that last ounce of accuracy from your rifle, and SpeedLock Systems accomplishes this with a minimum of time, effort, and cost (must be installed by a competent gunsmith).
It's been proven that primer ignition is a critical factor in accuracy and consistency. Another benefit of the alloy firing pin is that its lighter weight and more powerful spring results in a higher velocity striker. SpeedLock Systems parts deliver a higher energy impact faster and more efficiently.
Also, another advantage of our lightweight pin is that it ignites the primer with less movement of mass, thereby greatly reducing the vibrations associated with firing pin fall. These vibrations begin to cycle and oscillate the muzzle well before the bullet exits the barrel. A SpeedLock Systems pin reduces the level of this oscillation to the extent that the accuracy of your rifle may actually improve. This effect is easily seen by dry firing from a benchrest using a high powered scope. Watch the reticle movement "before" and "after" and the difference is astounding.
Performance is in the numbers!

OK is it fact or fiction?. I still want to hear from some SpeedLock users.
