I am wondering if it is good technique to adapt your shooting stance and posture to the target range. For example, I can take an aggressive stance for short range shots that allows me to shoot rapidly and stay on target by mitigating recoil, but that same aggressive stance is not very good for trying to hit a paper plate sized target at 100 to 200 yards. For longer distance I find that I can aim steadier when I am more upright. Assuming that you cannot kneel or go prone for the longer shots and you have to stand, is this proper technique?
As distance increases you may have the luxury of time / cover / distance as your friend. Combine this with perhaps the need for more precise 1 shot accuracy which may require more strict adherence to your basic fundamentals, particularly better control over your breathing steadying the sights, cutting down the wobble area, muscle tension etc… Because of all of this the time to break the shot may increase to the point that fatigue caused by a certain stance may become more detrimental than beneficial. When distance increases our need for one shot precision may be more desirable than speed and accuracy of follow up shots up close, so controlling recoil may not be as highly prioritized for a given situation. Of course there are many factors, scenarios, equipment, shooter skill etc, that plays a determining role.
There are 4 factors to consider when adopting a position:
Stability
Mobility
Observation
Cover
A good position will have as much as possible of each, balanced by the needs of the circumstance.
