Why do my shots curve to the right, regardless of barrel?

I am a newbie, but I have upgraded from my stock barrel already. My gun is a Tippmann 98 Custom.

When I shot my first 1000 paintballs, I was using the stock barrel. All of the shots curved to the right after about 30 yards. After getting my new barrel, a Custom Products 16", my shots were more tightly grouped, but they still curve to the right. All of the paintballs were RP Big Balls. The seem to match my barrel, according to the charts I've seen and the "blow" test, where you put a paintball in your barrel and try to blow it out. They blow out fairly easily if they aren't out of round.

Why do my shots curve? Is it because of the location of the velocity screw? It comes into the bottom left side of the gun.

i think your velocity might be a little too hihgh, Have you chronoed lately? but i think thatsg the problem.

it could possibly be the gun threads, on mine the stock barrel was a little to the right too.. but since i upgraded to flatline it shoots straight. It could be that or the paint your using... or velocity.

If it's your velocity it's more than a gentle curve, the ball zooms out straight then pulls a hard turn, and they general curve in multiple directions. I think it has something to do with so much force and wind resistance screwing up the forward flight.

it does the same thing at below 280 fps. when my co2 gets a little low it goes down to 220 fps or so. it still curved to the right, but not as much.

my new barrel cut the rightward curving down a lot, but it's still there. i just wonder if a lot of guns do that.

right now i just have a screw to control velocity. do the rear velocity adjustment setups make it where you can have the velocity screw barely entering the barrel and still get it to below 280 fps? i think that's causing the problem.
