    a miss weighted paintball will fly like a weather vane. meaning, the heavy part will lead and the light part will follow. this weight distribution will actually destroy spin. this is part of the reason why the FS round work, because the heavy part leads.
    However it also leads to begin with. you have no control over the orientation an unbalanced ball is loaded. Try shooting a FS round sideways, backwards and forward and see how big the grouping is. You will get deflection and it will be unpredictable unless you orient the same each time.

    Paint can separate fairly quickly depending on its quality to begin with.

      is a sphere, it doesn't have a tail like FS round. so thats not a concern. a sphere can rotate on this kind of scale (+/- 180 degrees) without effecting target location. it will stabilize out very easily without effecting much at all.

        Nah, you will see a significant difference in groupings between unbalanced and balanced balls. It won't balance out spin and deflectionary motions within one turn or half a turn.

          you made the claim - show me.

          figure out a way to make a nice paintball off balance without effecting its external shape, and shoot them and show me.

          its round dude, how simple does it need to be? all paintballs spin, on the scale of spin they typically see however, there is pretty much no effect. whats an extra 180 degrees?

            Actually you made the claim that no equipment-based choice can affect accuracy, of which paint is an equipment choice. You also made the claim that air is the largest influence, so it is incumbent on you to demonstrate that. This is all based on your original post.

            It's not simply an extra half turn. It will take many turns to stabilize, if it ever does at all, as we know balls can have quite a bit of random rotation as they leave the barrel. Anyone who has seen a two-toned paintball in flight knows there is significant rotation during flight.

              if you consider paint to be an equipment choice, then fine your right. i dont personally because paint is more often shoved down my throat no matter how crappy it is at FPO fields.

              so you agree there is significant rotation, then why is a bit more any issue? it rotates, big whoop?

              i find the whole debate pointless anyway, i have shot 6 month old paint that wasn't separated so the weight distribution point is pretty weak anyway. the SHAPE of the paintball will change long before the fill will separate out. hell, the fill will leach out of the ball before it separates too. so we are really talking about a pretty rare occurrence, that i doubt the OP is dealing with.

              in conclusion: buy a small bore barrel. if you like consistency (which does not translate to XY accuracy very often) then get a two piece, if you like efficiency, get a one piece. then buy good paint. thats the best you can do without changing the projectile your shooting (like the FS rounds)

                I think I see what some of you are saying: the balance of the ball aside, if the energy imparted on the ball is the same, but there are small differences in mass from ball to ball, the departure velocity will be different, but the flight distance will be somewhat moderated by wind resistance: i.e. a heavier, slower ball will have the same momentum, but less loss to air resistance than a lighter, faster ball. The net result would be that the air resistance tends to have a moderating influence on flight distance.

                The best way to regulate distance, and therefore trajectory, would be to measure measure pressure and firing cycle time for each shot, and then try and adjust it to keep it constant, but I am guessing most markers already have that pretty consistent.

                  Exactly, guns are already set up to try to be consistent. Trying to actively change the operation of the marker is actually undesirable.

                    Ok, so, I guess my conclusion from all this is that there is little out there that will give me any improvement over my current setup.

                    Currently, I have a bigshot (for sale btw), a bigshot with an Apex tip, an autospirit, and a SS freak kit as backup when the BYOP paint does not match one of the former. I use a crossfire preset 850psi tank.

                    I -am- thinking about getting an adjustable reg for the crossfire tank, since it seems from the graphs in the owner's manual that came with my gun, that 900-950 psi yields the most consistent velocity. Plus, I would like to try the whole rapid fire thing by swapping a lvl 7 in, in lieu of my lvl 10. Any suggestions?
