Hi i am new to paintball and my 98 custom is still on the stock setting. My only mods are a eyeforce hopper and a bang stick 16 in barrel. The barrel has great range and accuracey but i was wondering if i would gain by turning up the pressure. How much is excessive? i dont want to just waste gas.

I live in the country and play woodsball on my own land. I was just wanting maximum range without wasting alot of co2. On stock settings the 16in rifled barrel holds a very tight and predictable group and is accurate out to 40 yards. This sounds hard to believe but i was shocked as well. Its not like the barrel didnt cost more than the marker but i can use it on any marker assuming i get the end peice for it. I have had hits over 40 yards but the ball did not break. Again if you dont believe me on the range then buy one for yourself and be amazed.

If you're shooting well matched paint, and cleaning after EVERY break, a predictable group is conceivable at 120', but as any science major can tell you, there is a difference between accurate and precise. exactly how tight are your groups?

If I am shooting at a tree 3 feet in diameter 40 yards away from my house on a full tank. Every ball lands within 3-4 inches of the aiming point. I havent had a break in this barrel, I am using the .69 tailfin and Visibile Impact paint from Walmart.

I've never used tailfin paint, 'cause I play at regulated fields, so I don't know about their perfomance, but what you're talking about suggests 3.6-4.8 MoA from a paint gun. I find that very hard to believe. .687 round will generally produce 24 MoA, and myself and a very few others have gotten down to 12-14 MoA with round stock, but not at the distances you're talking about.
Also, how are you getting Tailfin paint to load with an eyeforce hopper? They're non-directional, for round stock.
As to turning up the juice, you're doing it after the gas has entered the gun if you're adjusting the velocity screw on the right hand side of the receiver, so the reg is already preventing you from over pressurizing. It come down to two questions; How fast do you really need to shoot, and; how many shots do you want to get per tank fill?

When i said tailfin i was talking about the different sized ends that you can put on the hammer head barrel for different ball sizes. I am just using normal paint. I was looking online and i found some aluminum tubing that has a .685 inside diameter and is .875 outside diameter. The part where my hammer head threads into the tailfin is
.814. You can buy this stuff up to 12 feet in length. It would not take alot of time on the lathe to turn it down and thread it. I would like to test how far a .68 caliber paintball can travel. My hopes are that the longer barrel will let me achive more velicoty without using enough pressure to destroy the ball. I was thinking a 4 foot barrel or 6 foot barrel. This would not be used to play because its too heavy and im sure these balls will be moving fast enough to seriously injure someone. My goal is to break a record for distance traveled by a .68 caliber if there is one. As far as you believing me, i really dont care. Go youtube the bang stikxx 16in barrel. We changed from smoothbore musket for rifles for a reason. Granted a round ball doesnt bennefit from it as much as an pointed projectile but it still has its bennefits over smoothbore.

...also granted that muskets and rifles fired a solid metallic projectile, mot a pill capsule full of gyroscopicly unstable goo.
A longer barrel will actually decrease your muzzle velocity, it's a diminishing returns scenario. As the barrel length increases, so does the contact area between the ball and the barrel, thus so does the friction generated, slowing the ball. Double the length of the barrel, and you have to double the pressure, just to maintain the same velocity at the muzzle. It's a Red Queens Race.
The sport of paintball has been around since 1982, and it those 27 years, knowing what the firearms industry has to teach us, the best answer is smooth bore, brass construction (Palmers) not longer than 16".(and many will tell you not longer than 14" or 12")
