IR3 Blowing up paint, NOT chopping. Help!

[Novus6736]

Hi.


I have a IR3 MEM 6 with cobra bolt and if have been having a problem with the gun breaking paint when I shoot fast. I have the COPS2 set properly and the gun is not chopping the balls in half, instead it is blowing the paint up on impact. When this happens, I will take the barrel off and and the inside of the barrel is covered in paint. I also take the bolt out and the tip is covered in paint and some paint oozes out of the breach area. So it is not chopping and it is not just breaking midway down the barrel. I have been using a big bore barrel and the balls fall through with no resistance, so the paint is NOT too big for the barrel.

I considered the possibility that the paint is brittle, but the paint was not all that brittle. I used my 2k2 Timmy all day and I didnt blow up one ball the whole day. I know that it runs at a lower pressure though, so maybe that is why the timmy didnt break it.

I have my dwell set at 14, and I was thinking that I could bump it up to 16 but I dont want to lose any efficency. I also have the ball detent set properly, so that is not it. I was thinking that I could take one shim out of the LPR as well.

Finally, I was thinking that maybe the cobra bolt is causing the problems. I never have had the stock bolt so I dont have a basis for comparison. Does anyone know if a bolt can cause this problem?


Can someone please help me fix this or if anyone has had a similiar problem please tell me how you cured the problem.

Many thanks,

Al

you really need to experiment with changing your dwell. I have heard of people saying that your bolt, or even your breech might have a burr or something that is cutting the ball, but really turn the dwell up

it sounds to me like you are chopping,the sens could be too high and the cops sensor is being "tripped" via vibration. take all the paint out of the gun, put on live, cops ON, bas of 20. pull trigger as fast as the wind, it SHOULD shoot a STEADY , SLOW, string of shots. if you hear it shooting erratic or steady for a while and then all the sudden it shoots two or three shots VERY CLOSE together, then there is your chop problem. to fix= turn sens down or grease BOTTOM of cops sensor. after fixed, return bas back to preferable setting. some one please corect me if i am wrong. brian5

Chopping would jam the marker and not allow it to cycle. He's breaking paint but not chopping as the marker is still cycling.

Wow, way to post a false statement there big guy. Chopping does not always jam the marker- in fact, it will rarely jam the marker, in at least my experience. I can get my gun to chop easily- if I tune my Cops2 correctly however, I don't have this problem.

Guys,

Thanks for the help. I will try adjusting the dwell. Also, the gun is NOT chopping. It is blowing the balls up. I think the bolt is just cycling with too much pressure so i am going to drop the LPR and up the dwell and see what happens,




Also, Do you guys notive that with COPS2 off you can really rip on the trigger and get some good bounce, but with COPS2 ON and with an EVO2 I cant shoot nearly as fast even though the loader should keep up.



Anyone?

If you can't shoot fast with cops on, make sure you cmrof is turned up to 16-20. Then check your sens and bas settings, experiment a bit and you should be ripping.

[brian5]

novus, try the dwell first, but if it dosnt change, try the sens test as i do it, dont do a drop test. my new mem6 came with an adendum in the manual with this new way of setting the sens, yours should have also. i have been shooting nothing but angels since 1999, and have chopped MANY balls (9v revy was all you could get) and my bolt has only stuck ONCE! ( 2 weeks ago to be xact)
i am only trying to help, brian5

Haven't noticed what you're talking about with ROF. But at the same time my CMROF is at 18. I think everyone is on the right track with the Dwell thing.

[Furious George]

Wait, he said that balls are rolling through his barrel with no resistence. Sounds like paint may be rattling around the barrel at high rates of fire and breaking. It can't be very air efficient to have paint rolling out of the barrel either.

At practice we shoot some low grade paint and a lot of its out of round or various sizes. On the rare occasions where I break paint in the barrel, I invariably have paint on the face of the bolt. It almost always happens when I'm ripping on the trigger too. Try a better paint/barrel match along with turning your dwell up.

[acoenfam1]

Good catch grasshopper. Didn't notice that line but yes another possibility.

[freeloader12345]

Big paint very small bore?

[acoenfam1]

Not if the balls are just falling through the barrel.

[Old Timer]

Brian, am I understanding your post correctly that the new mem6 manual addendum says to not drop test to set the sens, but to instead do the rapid fire with the cops on and listen for a glitch in the firing delay ??? ..Thank You...Chuck

[acoenfam1]

No I don't think that's what it says. I don't have mine with me but if I remember right all the supplement deals with is the different settings (ie BAS) not the Drop test. I sent a copy of my supplement to the webmaster to be put on the site but I guess it didn't work or something. Can't exactly check it not though.

first of all i have chopped at least 1 paintball in all of my guns that ive ever had from outshooting the hopper when accidentally turning off the cops2,vision, ace, etc, and the bolt never jammed and there was no paintball shell left so you could very well be chopping. it could be cuz of a bad ball detent or cops2 isnt set up properly. with barrel breaks you should not have paint on the bolt at all. i have had a barrel break in my ir3 a few times when using REALLY REALLY crappy paint.(old small, deformed, and brittle diablo seconds) and never had paint on my bolt.

also im willing to bet it is the ball detent. true, higher dwell is easier on paint, but if nobody else breaks paint on dwell 14 then theres no need for you to run any higher because obviously something else is wrong. the stock ball detent on my ir3 BARELY stopped smaller paint from going right by it, even when it was screwed in all the way. this cuased me to double feed and break half way down the barrel. i got a cobra indesruc-detent and started using decent paint and i havent had a single break or chop in like 7k shots.

Guys,

Thanks for your help. I am going to fool around with it this weekend and see if I can get it working good. The gun rips as it is it just sucks to break balls when shooting real fast.


Also, what is this alternative way of setting the COPS2? I did not get any addendum. Thanks!

[brian5]

well, MY adendum DOES say to set up the sens differently. it just dosent say,''dont do drop test". it tells you basicaly the same thing that i said in my first post. i dont know how to put it on this site because i am not very good with computers.but i wll get a friend to do so if any one wants me to. i am not saying this is whats wrong w/ dudes gun, but the sens setup on mem6 IS different.

[acoenfam1]

Not a p[oint of contention that the COPS 2 is set differently. Just saying that I couldn't remember if it said anything about the drop test. Was trying to agree with you

[brian5]

its all good dude

[Jbautista]

OR it could be your paint. thats what happened to me.

[brian5]

aint got a scanner so this will have to do:
my ADDENDUM says:
this is for mem6 (c.o.p.s 2)
1.) ensure c.o.p.s is ON
2.)set SENS level to 12
3.)set BAS level to 20
4.)ensure NO paint is present in the ANGEL IR3
5.)fire the ANGEL IR3 (marker should fire rapidly SENS level too sensitive)
6.)reduce the SENS level until the marker starts to shoot slower at the BAS speed 20, note the SENS level (ex. level 9)
7.)fill the hopper with paintballls, ensure that the hopper functions correctly
8.)shoot the ANGEL IR3 rapidly
9.)minor adjustments may be done at this stage, by increaseing OR reduceing the SENS by one level at a time. Verify your settings by switching your hopper off and the rate of fire must reduce. If this does not accur adjust the SENS level down (ex. level 8)

in my opinion:you want the SENS as high as you can get it, and it not be too sensitive. this equals faster ROFs

still, not say'n this is whats wrong with the gun, but this is the correct way to set the SENS on C.O.P.S 2 mem6


hope this helps---brian5
