Brutus, respectfully I suggest your off hand shooting was successful due to practice rather than by the quick lock time. Practice leads to improvement, improvement leads to confidence.
The idea that a fast lock time can improve ones shooting makes my head hurt. Lock time, whether slow or fast is best measured in milliseconds, 1000 milliseconds equaling one second. I have shot rifles with what were said to have very fast lock times, such as the Kliengunther and the 788, and my scores never seemed to be any better with those rifles than with my M-17 Enfield which may have had the slowest lock time of any bolt gun in history. A good trigger, one that is neither too light nor too heavy, that is free of creep and over-travel, and is free of perceptible movement when it releases the sear, is far more important to the marksman than is the lock time.
