    Unfired rounds often get stuck in the chamber.

    Forgive me if this topic has been raised a lot before. I haven't been here for a while. I have a Grendel with an old 2009 Satern Rifle Cut barrel and I often am not able to pull the UNFIRED rounds from the chamber. I have maybe 500 rounds through it in total.

    At first I figured it was just a bad round or something... but now I have noticed that it happens very frecuently (although I havent shot it in years until yesterday when it did so again).

    I am wondering if this is a "known issue" with these barrels?.... or if its "just mine"? ... And if a "known issue", what has been the cure?

    Thanks.

    Sounds an awful lot like your bullets are getting jammed in the lands... if you yank the charging handle back, will the bullet come out of the case and stay lodged in the rifling? If not, can you see marks on the bullet from being lodged? Are these handloads, or factory ammo?

    If your sizing die was not screwed down far enough to get the last portion of the case, you might have a swell and may need some small based sizing dies to bring your brass back in. Got a chamber gauge handy? Run your rounds against it if so.

    The bullet itself is not affected. After mortaring the rifle the round comes out intact, This happens with both handloads AND FACTORY ammo. I truly believe it is something related to the chamber, but I wanted to find out for sure if this was a more common problem and whether it took sending the barrel back to fix it,

    By the way I emailed Satern... How is their customer service?

    How much has the barrel been shot?

    Could be as simple as the chamber needs a good scrubbing. A good carbon solvent and a chamber brush would be my first step.

    This was pretty common with Satern if you got the barrel from Satern, though not all of them.

    I've finish-reamed 2 of them that I was building uppers with or doing Cerakote work, using a Manson SAAMI Grendel reamer.

    Very few shavings came out, barely noticeable. I used cutting oil, then polished the chambers afterwards with a mop and some bore paste, then cleaned thoroughly.

    Well, I decided to order a Manson finishing reamer. I figured it was a must to have.
    .... Hope this will fix my problems. I may need some guidance on how to actually use it without ruining my chamber....

    LRRP52,

    Is this more or less what you did??

    Well, I think I fixed my problem and here is how I did it:

    I got my very own Manson Finish reamer. It cost me 136 bucks delivered, but I figured that if it fixed my favorite gun, that then it was well worth it!!!

    As a lubricant I used CRISCO which I was told is an excellent lubricant for this type of application my an old time machinist friend of mine.

    I secured my upper vertically on vice and gently dropped in the reamer into the chamber. I turned it ONE full turn without applying any real downward pressure, just letting it scrape up axially whatever it might find WITHOUT cutting any deeper.

    After that one turn I removed the reamer, cleaned out the lube and shavings, and lightly polished the chamber with 0000 steel wool on a brass patch holder on an aluminum rod in a drill.

    I put the gun back together and chambered and unloaded 5 factory Hornady rounds and I could feel that it was easier, but still too hard; I was making progress,

    So I repeated the process two or three more times but on one pass I actually made two turns of the reamer instead of one!!! BUT like I said, I never applied any real downward pressure.

    On one pass in particular I did see some minute shavings and a lot of what I gather was CARBON on the cutting flues of the reamer.

    I stopped the process once the rounds ejected "normally" and very smoothly.

    I have yet to test fire the gun but I hope that I did not alter significantly the head space because I do not have gauges for this caliber....


    But after seeing all the carbon on the cutter, I thought about some issues that I have had with this gun early on which might explain my current problem:

    When I first built it, I only shot that cheap and MILD Wolf ammo. It worked fine. BUT AS I STARTED TO RELOAD for this caliber, I started having issues because (as I eventually figured out), my gun was WAY OVERGASSED by the hotter reloads. I would find the top end of my ejected cases covered in powder residue that was now blowing back into the chamber... and I guess this stuff was never really cleaned up properly and was left there to build up for a while...

    So I got an adjustable gas block (which fixed that over gassing issue), but it was too late because the chamber was now pretty fouled - although it looked clean and I did clean it every time I shot the gun.... but apparently not well enough!!!

    This created the roughness to not allow the unfired cases to eject easily.

    Anyway, that's my current thinking.

    I hope my experience will help others with similar problems.
