Barrel test----- I have a few more questions/ need paint suggestions

[Cow123]

So far if I was only told the diameter of the barrels I would not purchase an empire revolver or alum freak.

Lame.

[MANN]

Lame.

??? because why

[Cow123]

??? because why

Because I just bought one of those.

[MANN]

Because I just bought one of those.

lol. Which one? Do you like it?

Please remember that this test is just my oppinion. I am planning on giving what I beleive is the best barrel kit, and will provide reason behind it. I hope that everyone does not believe my results. I still have to try to sell them

I'm not going to blindly jump to conclusions or anything so don't worry about that.

Do I like it? I don't have air to shoot it yet, and the front piece has a dent in the lip of it preventing me from fitting my inserts all the way in, so I need to buy another tip.(this was purchased new too ) From that excellent example of quality, your deviation results seem all the more plausible. With a .0025 difference, my .687 could be bigger than my .689

oooh the irony, the empire kit and the freak kits suck, and sp is suing nps..lol, who cares, they both suck at making barrels

[k0m0d067]

you're using calipers to measure the I.D.'s??? sorry bud, but I've yet to see a set of calipers that were worth a crap at measuring I.D.'s any more accurately than maybe +/-.002...so as far as comparing the size stated on the insert, to what you're reading on the caliper's, I wouldn't put too much stock in your readings (although it would be good enough for comparing say one brand of insert to another...good enough for comparison, but not actual measurement...get me?

you want perfect numbers, send all that stuff to me, and I'll measure it with our Zeiss Contura, using poly-line scanning technology...accurate to microns...LOL and tell you how cylindrical they are as well...LOL shipping'd be a bear though...

I've already stated what barrel I believe will win your contest, but I will be very interested to see the actual outcome...

O dear me! I'm in the wrong thread, sorry Mann, I was refering to your barrel selling thread, let me move it over. Ok its edited now, sorry everyone.

It's kinda pointless to worry about exact barrel bore diameters when paintball sizes vary so much from ball to ball.

Measure and match the paintballs instead, and shoot them through each barrels advertised bore/insert size.

[shakes head]

At least someone should dig up the graphic I did on how to do shot pattern statistics properly. I seem to remember it was in one of the magazines.

Barrels... the bane of my existence...

Mann;

I can help you with get some results VERY quick from this test you are about to do based on my own tests I have done.

I put a barrel on my gun, loaded it with paint, aired it up, and fired it.

The results were pretty consistant,..... the paint comes out the barrel! LOL!


U know someone would have said it at some point!


I didnt see any PMI Perfect-Bores or J&J Ceramic 1 piece barrels in there (unless you have them in a very dark color)

I have a few if you want to buy or borrow for your testing,... PM me.

Paint suggestions:

Tom will have to correct me here but your going to get more "consistant" results with Tom's Perfectly round paint or Re-balls. Unless you checked each ball before loading and made sure it was the same size no matter what. Doing that seems a bit un-likely though.
I havent shot it in over 5 years, but back when I played tourney and you wanted a good ball that was easy to track and was consistantly shot, Marbalizer was the way to go.

Might wanna ask Tom,.. see what he can suggest.

Statistics Without Math??

If you want to impress on your parents that paintball is more than just a game, tell them in the forum tonight we were discussing a one sigma deviation of a standard distribution based on data taken from two shot groups. Mention you are worried that your error bars were getting out of control due to a lack of input but your Bell Curve should look better after more runs. That might net you some bucks for paint!

On another note Tom Kaye's Tech Tips will be a monthly feature in Action Pursuit Magazine starting in two months. We will be extending our search for truth, justice and the American Way to the rest of the paintball world!

hmmm thats intersting that you say that. I have a nist calibration from AAJanson that states that they are accurate +-.0005" (these are not the Lowes 16.99 special version. I believe that we spend a few hundred dollars on them). We use them at work for measuring the internal diameter for nozzle calibrations. They have to be very accurate to allow for permitting for air emissions. I used the same procedures that are stated in the CFR (dont remember the exact number) to measure the internal diameters.

Either way like you stated they will tell me between the difference between the different kits.

Yes, and no. Ill agree that paintballs vary in size, but if I am spending 100+ on a barrel I expect to recieve a barrel kit that has a range of inserts instead of a kit that is hit and miss.

I am hoping on buing a high enough quality paintball that the size varriance is minimal. I am mulling over the decision to just use reballs instead/with paintballs.

:rofl: I have read through quite a few threads reading your results about rifeling a paintball. I plan on completing the statistics using your method, and some others for each barrel.

p8ntbal4me: Im probally going to take you up on purchasing/borrowing your barrels. I dont have either of the two you listed.
After seeing others oppinions and thinking about it a little more I believe that I will probally pick up a case of reballs to use to suplement the test. Maybe 20 marbs/xball gold, and 20 reballs per barrel/bore.

Beemer: I had already read them, but thanks anyways.

[p8ntbal4me]

Just shoot me the PM,.. I'll take some pictures so you can see em,... I have some others too if your missing em.

PMed you bout some other business too,.. send replies whren u get a chance

Wow, this is really kewl. I love you Mann. But not in a freaky way, just paintballer luv. Keep up the good work!
