i cant be reading that right 21 inch under bore was the best?

[ChrisB]

So the 21'' was the best? Can someone explain this or something.

I'm really confused, so what are the conclusions?

on the one-piece page of the data sheet, it reads, "target at 50 feet, all measurements in inches." I'm guessing this is just a typo and that you may have reused the data chart from a previous test, but I want to make sure.

and very nice test. interesting data, I'll be thinking about this during class tomorrow

cp help us we're confused!

[Toriphilewill]

Is 0.001" considered underboring? I know the .682 barrels are smaller than the paint size listed as .683, but is this the underboring effect being discussed? How many different DXS balls did you measure to come up with a .683 size? Why not underbore the .685 frostbite with a .682 one-piece? What kind of two-piece barrels did you use and what is the back length?

Do you wanna give a bit more info on why and how the experiment was conducted?

Edit: deleted edit question.

• From what I can see from the data, the two-piece barrel has two distinct experiments in the data. The first tested the same barrel length on 3 barrels, but changed the bore size. The second set, bore-matched all 3 barrels, but the length changed.
  
• The one-piece data set has a bore-match on all 3 barrels, but different lengths (same experiment as two-piece). The second set of data has an overbore on all 3 barrels by 0.008"with a small variation in barrel length (not the same experiment at the two-piece)

Here is a suggestion, why not keep the same barrel length on 3 one-piece barrels and change the bore sizes, to make a comparison to the two-piece data set? Edit: deleted statement.

Also correct the mean for two-piece barrels .686/12" is 0.0 in google docs.

i am a little unsure of the question. Pardon the ignorance. Is it which barrel is the most accurate at 125 feet or is underboring overboring better at that range?

[cockerpunk]

sorry, fixed the data tables.

all barrels were shot with DXS silver at .683ish, and at 125 feet.

i was using the old 50 foot data tables with new data, sorry for the confusion.

I think what people want is a statement saying "______ is the most accurate". Seems the chart is a little hard to understand.

if thats what people want then they came to the wrong place.

[wgp2002]

i wasnt looking for that but im not that great with the charts and stuff and i had gotten confused what the question of the test was.

i dont care what winds up to be the answer its more to just satisfy the curiosity of the game.

lol. I want the truth, and I can handle it! I just have some concerns regarding the data that are in my above post.

[Leafy]

I'm just confused that it looks to me that the 21 inch barrel was the most accurate and that goes against everyother test i've ever seen.

no next year. I'm in the joke of a class called linear algebra right now.

[Xcessive]

Hmm, what I'm seeing is that bore matching/slight overbore looks more consistent than underboring. Which is contrary to what we were thinking

And 21" barrel seems to be the most accurate, despite it being the least consistent!!!???

This is interesting, maybe I'm reading the data wrong...

haha im retarded... PsychStats just came back to me... (sorry its been a while)

just dont ask me to do ANOVAs..

anyway what barrels were these again?

[CrazyLittle]

I think the one SAFE conclusion we can draw from this data is: if your PAINT is consistant you'll get good results.

[wgp2002]

I thought the SAFE conclusion comes from CP's sig "The ultimate truth in paintball is that the interaction between the gun and the player is far and away the largest factor in accuracy, consistency, and reliability. "

but i am curious to know what barrels are used so i can find out what tolerances they use in their QA for their barrels.
