I keep hearing that but it's just plain not true. The myth started when the famous open bolt vs closed bolt test was performed which proved that closed bolt operation in the exact same circumstances as open bolt operation is no more or less accurate, which is perfectly true. But somehow that spun out of control into people saying that no gun is more accurate than any other.
1) Consistency - the consistency of the gun greatly affects Y-axis accuracy...I don't think I really need to explain why...this one should be a "doh" type realization.
2) Platform Stability - A shot is not a single moment in time, it is very short yes, but not instant. The smallest deviation in gun position from the time the paintball starts moving at the beginning of the barrel and the time it gets to the end of the barrel changes the angle of the ball's vector by much more than just the micrometer movement itself that happened. Less moving parts (such as the 1 moving part in a DM3) and more weight (such as the 3+ lbs DM3) helps lead to a stable shot platform. Of course when it comes to multi-shot accuracy (i.e. a "rope" of paint) this is even more applicable, but it does apply to a single shot as well.
3) Operating Pressure - This is the only one that is not easily proven fact, but personally I believe that the less stress the ball undergoes during the shot the less deformation that happens to it and not only less breaks but also better accuracy. I mean for god sakes if a higher pressure gun can literally break balls that a lower pressure gun wouldn't have then isn't it safe to assume it might dent one or two that a lower pressure gun would have left round?
