Tippman 98 Custom stock barrel which was much better
Tippman 98 Custom, Smart Parts Progressive 16" Barrel, 20 oz CO2 tank, Response Trigger, 12V Revolution, Homemade CO2 Cover
Draxxus Rec-sport, they are really cheap, I mean the cheapest that I could find, and they seemed to hold up relatively well
Too big, lobs balls, totally inaccurate, finish wears off too easy
this barrel is the worst barrel that I have used in my life. I bought this barrel because I thought that the stock 98C barrel was bad, but this barrel is way worse, it lobs balls, the balls twist out of control straight out of the barrel and always hit more than 5 feet away from what i was aiming at. I might have hit it against a tree once or twice which didn't do anything to my hopper or gun, but the finish on the barrel wore of all over just from that. there aren't enough holes to let air out. I found that any barrel that has slits on the tip instead of holes is much more accurate. A slight upgrade to improve accuracy would be to drill holes in middle of the barrel to get rid of excess gas, this would cost smart parts almost no money but they have not done this, WHY!
This barrel is horrible, don't buy it. I warn you, this is the worst barrel ever made and is a waste of money. go out and buy a werks or a flatline barrel, even a cheap empire barrel is way better but only $10 more.
try matching the paint to bore pretty much any barrel will perform at least well if match the paint, also if u ported holes in the middle you would have no pressure behind the ball to continue to push it. it would lob even more
Sounds like you had a paint/bore matching problem. There is a simple way to test this by placing a ball in the barrel and see if it rolls out fast (small paint), sticks very slightly and can be blown out with little effort (good paint/bore match), if it can't be blown out without causing you to black out (the paint is to big). If the paint you were shooting is small it will bounce down the barrel and cause the curving you described.
The porting does not affect the accuracy of a barrel, only the sound level and amount of gas used to push the paintball.
Finally, the finish I have not seen or heard of anything like this so there may have been a defect in the finish. Did you notify or check with SP about a replacement?
I wrote this review and I honestly have to say that I broke paint if i truned my velocity up and if I turned my velocity down than my balls went maybe twenty feet. the progressive barrel shot 80% at 100yds, 50% at 150yds and 20% at 200yds. the stock 8 1/2in. that came with my gun shot 90% at 100yds, and the rest was the same.
