Paint to barrel match? Is it really a joke?

[deadeye9]

Bill Mills got some interesting results when he tested the SM1 barrel system:

http://www.warpig.com/paintball/technical/barrels/sm1/index.shtml

He used an electropneumatically controlled trigger actuator and a bench mounted firing platform. The paint/barrel match that gave the best velocity consistency was not the match that yielded the best accuracy. Also, accuracy DID vary with different paint/barrel matches. Similar results are probable from other barrel systems.

sorry bout the newb question, but i just picked up my pipe kit yesterday, now i was told to use the size that is just smaller than the size that allows the paint to just roll through....for example im using .692 and im shooting tork. is this right because the .695 just let the ball roll right through

Neat article.

The best target performance came not from the insert that gave the best velocity consistency, but the one which was best matched to the paint with a blow test.

"Matching inserts to paint used was done with a traditional blow through test. Setting a paintball in the breech, if it blows through with a light effort, it is considered a match."

It sounds like this would be the same as choosing the next smaller size from the size that lets the ball roll through.

My opinion is this. Use a large bore barrel so all the paint will go through w/o barrel breaks.But more important is to buy a good quality paint. Low quality paint will effect your accuracy more than any other factor hands down. Out of round paint with large seams can't fly straight with any barrel , much less matched.
The biggest thing you will see using a (too) large a bore is less effeciency. I suppose some markers with super tight tolerances might not chrono right if the bore was too big. Anyone with a cocker also knows the dangers of the rolling ball.......
I use barrel kits anyway , but tend to oversize the bore just for the decrease in barrel breaks. I mean , honestly , if you break a ball in the barrel your accuracy is gone anyway. So if I loose a little for being "unmatched" vs a lot for a break , I will take the reliabilty of the less....

Yup,
I use dye ultralites. I have 3 different size backs. I use a short tip for hard fields, and a long tip for air fields. Thats it.
I don't like the "insert" stuff. Expensive thin walled aluminium tube inserts sound chancey in that they could easily end up "not round." imho.
Also, in years, I've always had pretty good luck with dye barrels.

Paint to barrel match isn't a joke - if you take a selection of different markers, securely clamp them in place in a controlled environment, provide them all with an equally consistent air source and use perfectly round paint, then the only thing that should effect their accuracy is the paint to barrel match.

That HAS been done. The paint to barrel match did NOT affect accuracy.

Generally speaking a tighter bore will give you better efficiency and a looser bore will give you better consistency (all up to a point). Since the more consistent the more "accurate" a looser barrel is "more accurate". I could go into long explanations, but no one cares. If you happen to, read the paintball physics thread in Deep Blue.

half of it is the boar match up and the other half is a longer barrel to prolong accuracy

[AGDlover]

oh ya i know this because it was my 8th grade Science Fair project

I would like warpig using all the same stuff to use the largest bore and see what the accuracy was like, just to prove that you don't need a good match to have good accuracy. As long as the bore is larger then the paint, you should have good accuracy.

If you came up with longer barrels = more accurate, you should've failed your science project.

Has anyone else noticed in this thread the following trend

Problem: I was not shooting accurately or breaking balls, so I switched up to a larger size.
Conclusion: Bore sizing matters

I, however, do not see this
Problem: I was not shootiing accuratly, so I switched to a smaller bore size

My conclusion: My .691 or .692 barrel should work pretty good on paint designed to be .68 caliper. It seems to me that the problems people noticed only involved too tight of barrels.

yep, and too small of a bore size means barrell breaks which then totally screws up your accuracy. i played today for the first time with my pipe kit, and omfg, i couldnt believe the diference. no breaks all day, and there was a huge diference in my shot placement.

so IMO, bore sizing > non bore sizing
