Alright so I am tired of always hearing that barrel X is better than Y. I have decided to try to test out most of the top barrels against each other to see if there is a difference, and try to determine what barrel is "The Best"
So far I have aquired ~ 30 different barrel kits/barrels. Ill include a list later, but here is a pic of some of them.
The gun will be setup in a vice. It will be shot ~60 ft (I havent decided a firm distance and am open to suggestions)
The shots will hit a piece of paper ~ 36" X 24-30" Ideally the paintball will go through the paper without breaking, and hit a sheet which will catch unbroken paintballs for later practices (the paint will not be used twice). Each shot will be measured on an x y axis to the nearest 1/4".
Each barrel/insert will have ~ 20 shots of 5 different types of paint. The types of paint will be PMI Stinger, DXS Rec Sport, Xball Gold, Diablo Heat, and Reballs (the real ones), and RPS Marbs (A HUGE THANKS TO p_aint_fun on AO for donating 2 cases)
For each shot the velocity will be recorded with 2 chronographs, and a radar gun (the red chrono was calibrated within the last year, and I have tuning forks to tune the radar gun with) the yellow cheap chrono is just that. I want to see how far off of what I call correct it is. The marker will be reset to 280 fps with each barrel. The velocity will be adjusted in accordance to AGD specs.
The maximum sound level of each shot will also be recorded for each shot (just because im intersted to see what barrel is quieter than another.) The results for this will be the percent of noise reduction. A baseline for each barrel will be determined by dry firing.
I am also taking the internal diameter of each barrel/insert to also see how close of tolerances each companies hold their products to. The actual/specified diameters, and the weight of each barrel will be recorded. some of them are What little experience I have in manufacturing/process the percent error just would not fly.
all measurements will be recorded with calibrated equipment. All barrel dimensions/weights will measured with nist calibrated calipers/ scales
I know that paint is not perfectly spherical that is the reason that paintballs do not go straight. It will be very hard to determine if the barrel is causing the inaccuracy or if the paint is causing it (the majority will probally be the paint). I am going to do my best to get a range of paint therfore eliminating that problem.
I have seen barrel companies state that our barrel is better than theirs because here is our shot pattern and here is the competion's shot pattern; and ours is a tighter pattern therefore a more accurate barrel. For anyone that is looking to purchase a paintball barrel that is smart enough to research their purchase i would like to provide data/reason to purchase one barrel over another. I have no ties with any barrel company, and would consider this a blind test.
I know that probally over of 50% of players will still go get a 24" barrel thinking that it will be a sniper. This test is not for those players. At the least this will let me know personally which barrel is best for me. My personal oppinion is that the gun/barrel is alot less the problem as it is the person.
Another difference in different barrel kits is the tolerance levels that the company holds. If I buy a kit with X number of inserts that are a certain size I expect the inserts to be exactly what is listed on them. I dont want a kit that jumps around. If thats the case there is no point of owning a barrel kit we should all just buy a piece of .75" of pipe, and tape it to our guns.
