Hey guys,

So, 2 scuba tanks and 20,000 shots later we've got some interesting data.

Here's the video:


Here's the data sheet:

Here's the internal wear (or lack thereof) after 20,000 cycles

First! lol

ROFLMAO that is an epic ball catcher. Very innovative design.

And Cocker's hair = epic awesomeness.

Looks like it finishes stabalizing after the first 100 shots. The standard deviations after that are all within the norms recorded after each case.

Well done! That looks like a lot of work.

Very cool Reball catcher!

[.SP0NGE.]

Very cool! I love it.

I used that sliding 25 shot SD calc. shot #114 was the first 25 shot string that dropped below the long term SD - so IMO shots 90-114 were as consistent as anything else we shot. So yes, I call it 90. Sorry Danny - I think you guessed 120 in the contest. I think you were closest - but Price Is Right rules declare that you have to be closest w/o going over.

And actually, once we got the rig set up it wasn't terrible. Here's a tip - lubricate reballs. life is good when things are a bit slippery

Hey, no problem Bryce.

Wow im glad I took AP Stats this year, I can actually understand the spreadsheet this time

Actually I think there was a guy that bid 1.

I was a bit surprised that there was virtually no wear on the cupseal. Cant wait for the NT numbers to see if they reflect the g6r.

I had a feeling that "break in period" was complete bull...

I think there was a 22.

well, it's not complete bull. there was significant improvement over the first 90-ish shots.

[danath 34]

so we are seeing a *relatively* steady drop in SD over the first 500 shots. The gun seems to be breaking in over the first 500 shots. Now if I am reading this correctly, the SD values for the next 10 cases are kind of all over the place (seems semi random) so I would say it is well broken in within the first case. However, when you rebuild the ram, there is a noticeable drop in SD again, indicating that the best consistency is with fresh ram orings.

So what exactly is 'breaking in' in the first 500 shots? because as we can see from the ram rebuild data, the ram orings being fresh actually increases consistency. Is it the reg orings maybe? Reg seat?

I did have one question, though. What happened at shot #346? It appears as if something was changed causing a few low chrony shots and higher SD values. However, this could be caused by paint size variation. Also what was shot #347? Was it a low shot? Is that why it was left blank?


Great data guys! Interesting stuff...

[cockerpunk]

an interesting thing i would like to note is that the before and after cleaning shots seem to be at random. meaning, sometimes cleaning the gun made it better, sometimes a bit worse.

the blanks are when we missed a chrono reading. Usually it's when the second eye on the chrono didn't see the ball. It happens sometimes. shots 61, 85, 320, 347 etc.

I kinda see what you're saying about 346 - but actually it's only 3 lower than 345. All guns have odd shots from time to time. This one is no different. I wouldn't try to read too much into any one shot - it's the means and SD data from groups of shots that really starts to have meaning.

Wonder how this will correlate to a spooly? or any other gun for that matter. Is the G6R just a break in freak of nature because finished tolerances from BL are that good? hrmm we may be able to put a tighter ball park on "break in" times with all markers. I always thought the whole 10 cases thing was a little out there...

we will be testing a brand new NT11 as well.

[The_Economist]

Yaaay, the 10-case-break-in myth is busted!

This is gonna put some folks on MCB into a tizzy - but they will probably discount your methods and stick their heads back into the sand anyways.

My bet is that a spool valve gun with have similar results and that break-in is extremely rapid on all types of modern guns.

[IhasAcellular]

Naw, MCB will just say it takes 30 cases to break in a gun.
