Xcr break in issues

Ok so I was out today fired about 65 rounds with 3 mags. The results. I ha one stove pipe and about 50 percent of rounds flew 5 feet on gas setting 2 the others about 15+ I think the problem is my brass ejection bumper. I don't know the tech term.
The casings that were thrown out at 2 feet had dents right bellow and on the neck. And I put a empty on my bolt and slid it back to watch the ejection process and the casing hit the plastic brass deflector in the same spots the the dents are. The brass that flew 15 feet did not have these marks. Also no damage to the delfector. Any ideas? A fix? Could it be the extractor getting held up? Small amounts of brass was on the side of the ejector

Not sure if this applies to your situation but anyway here goes? I fired off about 500 rnds and halve of them are getting dents on the neck and most fly about 15 ft some only 5. The faster I shoot the better also I let the bolt slam the first one in.500 rnds no fte or FTf , just the dented cases. I posted pics in the reloading section I believe , and was told that this was ok. I'm using a Kel tec su 16 so I don't know if this helps. Oh I was using AE 55 g and winchester45 g.
 
Went out today with my new xcr to break it in. 50 rounds on norinco at setting 4 using 4 different type of mags. Not one failure. Brass was going 10.-20 feet. Changed gas to 3 and then 2 no failures. Ran some AE and then more norinco, all told 120 rounds and worked perfectly. Seems to run fine on gass setting 2.

Home now cleaning.. Small amount of brass flecks but that is it.

Even breaking in ran way better than my su16 and t97.
 
Good deal. Ya seems great on setting 2 when it's going good. But then somthibg happens and a empty will just pop out a foot. What's the length of your delector? And do you have a pic. Also do you have brass residue on the outside edge of your extractor? Does it move easily or is it a bit tough
 
Extractor is not as bad as the picture makes it. Simple wipe with solvent and it all came off.

Extractor is very tough can't move it with just my fingers. Does move when i use a rod or punch.

For reference. Today, right out of the box
150 rounds of PMC bronze in Questar LAR mags, gas setting 1, no failures of any kind with brass ejecting at 2 o'clock about 10 ft.
 
Ok so I found a few issues. As for the bendt necks on the brass it's coming from the feed ramp. As for the poor ejection it's from the ejection buffer. I removed it and it ran on 1 no prob. Did send brass at my 4-5 o'clock but no stove piping. I tried to grind down the brass delector but it still did it. Dosnt seem to be any damage to te ejection port so ill leave it for now. I think ill email wolverine with a few pictures.

All XCR's pound/dent the brass pretty hard on ejection, this is normal for this platform...its well know

Dents it as it chambers. If I drop te bolt on a new round then eject it slowly it's already dented. Hits the feed ramp and dents the neck

Odd. Mine does not do that. Even ejected brass are fine. My T97 was bad for denting the case mouth, and I can tell from my collected brass which can from which gun.
 
So how wet are you running it? The manual indicates that breaking in should be wet. XCR Forum indicates same thing very wet I believe. Manual indiates that the feeding issue could be lubracation.

I had a similar feeding issue....
Best to call Wolverine and most likely you will have to send it in for a Warranty Repair or Replacement.

I have some dented casings as well. I think maybe it happens when loading a fresh magazine on bolt release. The number of dented casings I have correspond to the number of magazines I changed so my inexperienced guess is that as the spring tension will ease from use and the initial bolt release will become smoother and less violent on the first casing?

Good enough for me. Now just the ejection issue
 
I have a 3 y/o XCR that still runs fine, and I run it on the lowest gas setting now without worry. It has basically never done anything wrong or did something wrong that I couldn't explain as simple user error.

Yes it does "D" the case neck mouths, this seems to really worry some people. It only really matters if you reload I guess, but, the neck resizer can take care of that no problem and I honestly don't find the brass wears out faster than expected, so no problem for my reloads.

For accuracy, shooting bulk American Eagle round nose 55gr, I get 3 moa shooting at 100 yards. For reloads of the same, 55gr round nose (Hornady brand), max powder charge (which I tested up to before settling on), I get 1.5 moa shooting at 100 yards, with a 3X power scope. If I move the target to 50 yards for shooting, then the bullets start cloverleafing nice and pretty in 10-shot strings, so that indicates the 3X power scope is probably widening the 100 yard results a bit for the reloads.
 
What kind of fit should the piston have inside the gas tube? I'm
Assuming fairly snug but with little force required to move. Looking at mine when the piston is
In the gas tube. It's disassembled. I have a whole mess of wiggle room. Damn near a 16th of a inch. noticeable
To say the least. Is this right???

Use quality mags, like magpul mags or whatever. Those 10-round steel mags will do that to cases as the case necks hit a perpendicular steel wall feeding out of the mag.
