You wont develop loads at 100 yards ever again

[QUOTE="MMERSS, post: 940187, member: 63748"] The video is a representation of pitch vs yaw “net” imbalance and has relatively minimal bearing on a shooters ability to better a group at say 500 yards as opposed to 100 yards. One way to approach the concept is to visualize driving down a straight road at a certain speed. Your vehicle hits ice or water and starts to fishtail back and forth. Your vehicle continues to travel in a generally straight line but the front of your vehicle swerves from left to right. The “degree” or angle of the swerving from left to right caused by the fishtailing decreases the farther you travel. Eventually your car settles down and off you go again in your straight direction. I have shot many groups long range that equate to better MOA dispersion than some groups shot at a much closer range. I haven’t yet equated this to the bullet “falling asleep” but rather toward a combination of more stable conditions, more consistent velocity spreads, and better released shots. One aspect with developing loads past 100 yards is confirmation of the effects of muzzle velocity variation when a chronograph is not available for record of the spreads. Many great groups can be shot at 100 with relatively high ES and SD. 100 yard MOA group potential will not hold to the same MOA potential with those high velocity variations at longer range. I develop at 100 and confirm at the longer ranges. [/QUOTE]
