heys guys new to the forums...but been playing for some time...
i have 98 custom with a J&J Ceramic Barrel...
i kno that the stock tippmann barrels suck thus leading me to buying the new barrel
i played today with a bunch of friends, but noticed this time that my pbs will go like 100 feet and the take an erratic course change by going strait up or down or a sharp turn to the right or left
if anyone can help me correct this or at least lessen the problem...it would be appreciated..thnks(im thinking it may be velocity)

Try cleaning out your barrel

**bobide** · March 25th, 11:32 PM

ah, most likely bad paint (is it old? are there dimpels?) or to high velocity.

***Madman1989*** · March 25th, 11:35 PM

barrel is always spotless...and i use xball bronze paint

**DayoftheGreek** · March 25th, 11:37 PM

what about the breech of your gun? Is that clean? Make sure its spotless.

***Madman1989*** · March 25th, 11:38 PM

kinda of a noob wen it comes to terms...im guessing that is the part the barrel screws into

**DayoftheGreek** · March 25th, 11:42 PM

correct. Its right where the paintball drops into the gun, sorry about that.

**PaintBallBob** · March 25th, 11:45 PM

the breech is were the ball drops into the gun from the feedtube(the thing that connects the gun to the hopper).
Make sure the feedtube, bolt, and breech are ok. If they are then maybe you got old paint or something

I think you're on to something with the velocity thoughts. Check it over a chrono if you have access to one.

Otherwise, see how the paint matches the bore of the barrel. Take the barrel off and put a ball in the threaded end. If it rolls through with no problem, it is too small. Small paint likes to spin sometimes and that could cause it to dive off to one side after flying a little.

would my local pb shop have a chrono? once again with noob questions...wts a chrono do? thnks

A chrono is a device used to measure the speed of paintballs. It is short for the full name, Chronograph.

It is either a stopwatch looking device that is handheld or a large red rectangular shaped metal box. you shoot your gun over them and it tells you the feet per second that your ball is traveling.

280 fps is standard velocity. Your shop would probably have one, but ive never chronoed at a shop before. I usualy use the one at the field.

i tried putting ball at the threaded in and it got stuck...lol

Torch · March 26th, 11:26 PM

Could you blow it out with your mouth? If so, it's a good enough fit.

If it got really stuck in there and you had to poke it out with a stick or something then the paint is too big.

***Madman1989*** · March 26th, 11:48 PM

well i tried running a ball through it with some army navy paint and i had to poke it out...but the xball could be blown out with hardly any effort....so maybe ill stick to only xball...because i think the only paint going crazy was the army navy paint....thnks torch for ur help
