Problem Chopping new SFL Help! Lukes Friend and a new member

[cphilip]

Welcome to AO E-SFL! We are going to see what we can do. Rest assured it is fixable and AGD will work with you on it. You are going to be asked a lot of questions untill we can find the single or multiple flaws in the feed system or bolt issues. We know they can and do run fine once the issue or issues is resolved. We are concentrating on the bolt right now. Have you read the other thread on some things to try yet?

Hang in there. We will get to the bottom of this mess.

I changed your title to draw better attention to the thread.

Let's bump this up so we can get this guys mag working for him so that he can convert more cocker owners.

E-mag problems

Well we went through alot of the gun, the best the gun shot was with the long nose bolt. I was shooting marbalizers but the paint did not pass the bounce test. Avg was 3 bounces, we did not have any fresh paint. I should get a shipment of paint tomorrow. We tried adjusting the ball detent to check for double feeding, we put two balls in the feed tube, shot the gun and the top ball would bounce out. Most of the paint we had breaking broke in the barrel not on the bolt. On the barrel to breech match, we looked through the breech at the barrel and noticed that the breech was actually a little wider than the barrel. Barrels that were used were Dye boomstick, Taso Pro Series, Armson Rifled, they all measured the same which led me to believe that the breech was bored out to much and that the paint was hitting the barrel and breaking. I would like the ACE installed in my gun, are there any available? Any questions just ask and I will try to answer them to the best of my knowledge. Thank You!

Ace isn't available yet... You'll get a free ACE for an SFL when AGD releases it.

Bringing this one up for the day.

We did some testing last night. I think we narrowed it some but until we get some decent paint we won't know for sure what's up. Here's what we found.

Bounce Test's in in 70 degree weather...

Test #1
Paint E-SFL shot last weekend. (Marbs.) New Paint
Bounces
1) 13 * High
2) 2
3) 2
4) 2
5) 5
6) 1
7) 2
8) 1 * Low
9) 1
10) 11
Average = 3.25

Bounce Test #2
RP-Lighting - Did not use this in any other testing. This was also new paint!
1) 1 * Low
2) 1
3) 1
4) 4
5) 5 * High
6) 2
7) 1
8) 4
9) 1
10) 1
Average = 2

Bounce Test #3
This Paint is a almost a year old. I shot this last weekend in my Micro Vert Feed w/MiniMag Valve. I had 2 breaks in 1/2 case. (Marbs..)
Bounces
1) 1 * Low
2) 1
3) 3
4) 5
5) 8
6) 1
7) 5
8) 16 * High
9) 3
10) 7
Average = 4.125

The paint used in Test #3 was used to do the rest of the test's.

* Single shot loaded 1 at a time.
Loaded 20
Broke 0

* Loaded feed tube with 3 balls.
Fired 1 shot, top ball bounced out of the feed neck.
Fired again, ( 2 balls in feed neck ) # 2 ball in feed neck was pushed up about where #3 ball would set IF it were loaded.
Fired last ball ( no other balls loaded ) Broke ball in barrel.

NOTE: We considered breaks to be "barrel breaks" even if the bolt had paint on it. Would this be correct?

* Next we loaded a Revy (New Batteries) with Test paint #3 and fired a string of paint approximately 20 shots. Broke paint in barrel. Cleaned the gun up, and did the same test ( 4 times total ) results were somewhat identical as the first.

* Based on what was posted by Load SM5, we tried backing the detent out just a little bit. The detent was set approximately 1/4 turn from bottoming out when the gun was received from ST.
Approximately 10-15 shots - paint exploded up feed neck and into hopper to gun adapter.... Detent returned to factory setting.

* Next we installed a SS "short" nose bolt.
Shot a string of paint and it seemed to be a little bit better than the same test we did with the superbolt, but basically the same results. We can't be sure of the numbers
because we don't have the equipment to count the shots fired. But again, it was a noticeable improvement, but not much. We did this test 4 times with the same results
each time. After each break we found paint found in the barrel, on the bolt, and a very SMALL amount in guns feed neck, but, not in the hopper to gun adapter.

* Next we installed the "long" nose bolt.
This test yielded similar improvements as the short nose bolt did to the superbolt. But, we were still breaking an unacceptable amount of paint, probably 1 in 35-40
balls. ( Just a guess based on how much paint I was loading in the hopper.) Again, after each break we found paint found in the barrel, on the bolt, and a very SMALL
amount in guns feed neck, but, not in the hopper to gun adapter.

* This is where we stopped. I wasn't to sure what to do with the data at this point. I would assume that a paint that rated higher in the bounce test would improve the
numbers, but that's a no brainer. We still have problems if 4-6 bounce is considered good and we are breaking 1 in 35 ( another guess ) with paint that rated 3-4
bounce.

I'm going to leave it here for now, I'm not sure what to do next. We could use some input. I apologize if the if my writing is hard to follow, let me know if I need to
reiterate anything.

Done - cphilip

Can you get a hold of a SS foamy style bolt? If you can, try the test again and see if it improves the results. I spoke with Jon at AGD yesterday because of similar problems with my SFL and that was his recommendation. This same recommendation was also posted in your earlier thread. Problem is AGD is out of stock on this bolt so you have to source it somewhere else or wait till they're back in stock at AGD. I hope to run the same tests you did on my SFL and will post my results. LOL

I wanna know if the thing has any Burrs, rough or missaligned parts when you look and feel down the body. Need to tear it all down to the body to examine that look with the barrel in as well.

[hitech]

Is the front edge of the bolt sharp? If so, it could be fracturing the second paintball in the feed stack and breaking it when it is fired. You can use a small file to take the edge off.

2000Sabre,

You can't just glue a foamie to a standard SS bolt?
I ordered some stuff from AGD last week, they sent me someone else's order by mistake, there were foamies in it, I shouldn't have sent them back.

cphilip,

Thanks.
Every thing you suggested checked out best we can tell.

hitech,

We tried two different bolts out of my two Mags, still breaking paint. They work fine in my guns.

[luke]

????????

Should we be having this kind of trouble with paint that bounce tested at 3-4?

[hitech]

Is the SFL a vertical feed? I think those have more of a problem with sharp edged bolts.

3-4 bounce paint should be fine IMO (I'm never humble).

Also, I'm sure Tom will get back to you. He just got back from a 12 day road trip and is taking a few days off.
