          I have noticed aboslutley no help from rifeled barrels or difference. I bought that crappy ole TruFlight straight rifled barrel. It was about the same as my stock barrel(tippmann). I only used it because it looked cool, and my noobish friends wanted me on their team because I had a sniper gun.

          And that thing was a B**** to clean if you get a chop or barrel break. Then it started shooting knuckle balls and I knew I was in trouble.

            I love how everyone says "this discussion has been done to death" and then jump right in the same arguements and discussion that have been done to death.

            Heres the "facts".

            1) Spinning a paintball IS with question possible and DOES without question have an effect on trajectory.

            2) No rifled barrel manufactured to date has ever been proven to effectively spin a paintball.

            Discussion over.

                well lets just jack the weight up about 100% and problem solved.

                It is that simple and it aint wrong. A rifled barrel on a Paintball gun does nothing for accuracy. We are talking about a paintball gun and not a musket.


                Peace Out
                I wasn't trying to imply it helped a paintball, I was just noting the direction of conversation about round objects not being influenced by rifling. Round, .68 caliber, 3 gram projectiles are not. That does not mean all round projectiles are not.

                  Yes, spin perpendicular to the axis of travel has an effect on trajectory.

                  It has been proven conclusively by TK that spin parallel to the axis of travel has ZERO impact on trajectory.

                  While the second fact is absolutely true, you're mixing concepts between 1 and 2.

                    1) Yes , used as a statement of irony and in an attempt capture the only pertinent facts.

                    2) Conclusively? I think not and not by a long shot. One person doing his own set of testing under who knows whos supervision or methods of control and for the sole purpose of testing 'accuracy' and few if any other factors.

                    3) Umm, yes....for the sake of rifled barrel discussion there is nothing left to discuss.

                        Could be , I don't know....don't really care either but if so then thanks for pointing it out.

                        All we do know is how it applies to the capabilities of a static rifled barrel....and as far as I know , I'm the only one one this board and probably one of only a handfull in the world of paintball who have tested AND manufactured rifled barrels BY HAND myself in various configurations.

                          BTW, Tom spun a barrel to 10K rpms (or so) and fired paintballs. They were no more accurate.

                          Tom has described his testing methods. I've never seen anyone else's testing of paintballs in flight to even come remotely close. Not even close enough to be considered testing the same thing.

                            So in conclusion RoamingStorm, rifling and/or spin do not have a practical effect on the accuracy of paintballs. Let it go at that lol.

                              I think the real issue is not with "does rifling a paintball alter trajectory?" but with the fact that paintballs cannot be "practically" made to spin about the axis of trajectory fast enought to have any noticable effect.

                              The problem is the liquid fill...even if you spin the shell, there must be substantial time allotted to allow the liquid to spin also. Otherwise the liquid stops the spinning of the shell abruptly. A rifled barrel cannot put "enough" (or long enough) spin on the paintball.

                              So to answer RoamingStorm's initial question, "When a paintball flies through the air since the paintball is a sphere does a rifled barrel do anything for it?" :
