i just got my Lapco Bigshot today.  and honesty im not that impressed. people say the barrel shoots completely straight all the way until the balls hits the ground, ha nit mine.  i shot and it doesnt even go that straight.  i shoot and the balls goes somwhat straight then curves.   then  a ball broke in the barrel.    but there was a little wind, but wasnt to bad.

i was using PMI RPS balls,   are those the right size?  cuz i must be doing somthing wrong,   i sure hope i didnt spend 55 bucks on some crap barrel.

I have had really good success with that barrel.

So check to make sure there is no scratches or junk on the inside of the barrel.

Also make sure that the paint isnt old and doesnt have dimples or soft spots.

i put a ball in and it went like an inch, then i tyed to blow, but the air just went around the sides of ball, and i couldnt get it out,  so i had to puch it back out from other end.

but i thought PMI was the right size paintballs for lapco bigshot

the paint isnt old, the barrel is complety smooth,  

well i wasnt shooting fast,  i think the ball broke in barrel

but there was a little wind,    still i went into the woods and it still didnt shoot that straight,

The paint is a bit small for the bigshot if that's the case. Since it's small and air can get around it easily, it's not unlikely that accuracy is lost. If the air can get around the ball it can mess with the trajectory and throw it way off target. You also won't get consistent velocities or range between shots because of the poor seal the ball makes with the barrel. If you can find some bigger paint you'll probably see better results. My bigshot works extremely well with most paint but there are some brands that even the bigshot doesn't really work well with. RPS paint is generally good but the different types vary in size so some are better than others. I like RPS paint for the strong shells and consistently sized paint but it is kind of small, I'd rather use them on my flatline where small paint is desired. I used to use proball until the stores around here stopped selling it and then I started using draxxus midnight and blaze a lot. I also use PMI premium sometimes. When I use the flatline though I almost always go for marbs.

i think its got to be the paint im using,  cuz why would i break a ball?

what paints do u recomend the best for Lapco Bigshot?

Diablo

will a little wind affect the ball?  cuz there was some wind when i shoot, just a little.

and i think it is my paintballs  because why would i have a ball break?

i  wish i had a chrono so i could see what my volocity is set at

other wise if i cant figure out what im doing wrong, i might have to get rid of the barrel 

Try some different paint, you might have gottin a bad box...

Also check your velocity, that could be a big problem.  With it to high it will affect your accuracy a lot.  With it being to low, your shot wont go a far as it should.

well like i said before i dont have a chrono so how em i supose to know where my volocity is at?

wait. i have an idea.  if somone could screw there volocity screw all the way in, and count how many full turns (360 degrees) you have it at. so i could put mine the same.   i want somone to do this that knows there volocity is set perfect like 280 fbs or somthing

yea, i turned my volocity down a bit,  it shoot a little better, still i had ball curves.   but then my co2 tank went empty. grrrrr once i get my volocity set to whatever its supose to be set at, (i think its like 280) then ill have to buy some different paint.   most people say diablo is the best for the bigshot barrel. so i guess il get that.   then hopfully my gun will shoot straight.

Exactly right. Changing the tank, barrel, or paint can change the velocity even if the velocity screw doesn't move at all. The reason is because of friction or pressure on the paint. Changing the paint can make the pressure change because the paint may be a different size and creates a better/worse seal with the barrel. Putting a different tank on or even just removing and putting the same tank back on can cause a variation as well, I've had it happen to me but I fixed it at the chrono before playing with it. Changing the barrel can affect velocity in two ways. The first is that it could be a different size and match the paint better or worse than the last barrel. The second is that the inside could be smoother or rougher than the last barrel and that means friction could be increased or decreased. An example of this would be with my SL-68II. When I put my ceramic on, it jumped up about 50 fps puttin it near 340 fps. If that's not enough of a reason to check with a chrono all the time then I don't know what is. I've also had my 98c, with the velocity screw all the way in, shooting around 300 fps. The velocity screw can move velocity up or down but it doesn't necessarily keep the velocity there all the time.

Like others have said, don't oil up your barrel, that will just mess up your shots.  First off, make sure your paint is the right size and not too old otherwise that affects the performance.  The only sure way to pinpoint your velocity is by getting it chrono'd.  Go to any local field and they should be able to do that for you.  Also, because you are running on Co2, sometimes you get liquid Co2 into your gun and you get some velocity spikes that can mess up your shot.  I don't know if your accuracy was consistantly off or if it was just a few shots but to reduce velocity spikes you can get a x-chamber that catches the liquid Co2.

Make sure you do some troubleshooting first, and if all else fails, the only explaination I can think of is that the barrel is defective, which would be a shame since the BigShot is a really great barrel.

Hope this helps and good luck!
