Thread: LTT Beretta 1301 shotgun ejection problem

  1. #11
    The hesitation in the bolt going forward is normal. It’s the friction from the bolt lugs rotation into the locked position. Under normal operation under normal spring tension, it should lock up completely.

    Did you happen to keep or take photos of any of the spent shells that didn’t eject? It might not be a high possibility but there is the possibility that it was an ammunition problem and not a gun problem.

    Had any of those rounds ever been run through the action before? IE chambered and then manually ejected without firing?

    I was thinking the same thing. Perhaps that lot of ammo was out of spec… like the rim of the brass was too wide.

    I meant with the barrel removed from the shotgun. If you turn the barrel horizontally and look straight on at the underside of the barrel extension (the gas cylinder assembly and piston will be in line with the open bottom of the extension) you should see the peak of the ejector sticking up a bit proud.

    My bet is that the ejector is fine, but that's a quick check to ensure it's projecting enough to do the job properly.

    It seems to me there are three possible vectors for what I'm seeing in the picture:

    1. The shell is not extracting properly. The shell is hanging up in the chamber (most likely caused by ammunition, but sometimes it could be a defect in the chamber of the shotgun) enough for the bolt to rip the extractor off the rim of the case and the action jams up. You should be able to see some artifacts from the extractor on the rim of the shell head if that's what's happening.

    2. The ejector is not hitting the shell the way it's supposed to, preventing the shell from being kicked out of the action. for the shell to end up tilted outwards like that, it could be that the ejector isn't getting a proper bite on the case rim to knock it out. That could be caused by the extractor not having a hold on the rim of the shell, or because the ejector isn't set up right.

    3. The bolt's travel is being retarded in some way. Could be something up in the trigger plate assembly or the ammo itself not giving the bolt enough gas to run it.

    Shotgun ammunition is more sensitive than the metallic cartridges we're used to. They are more easily impacted by moisture and temperature changes than most metallic cartridges. I had a couple of ammo boxes get caught in the rain and I forgot to open them back up when I got home. The one with metallic cartridges in it was fine. The one with shotgun shells in it was a rusty mess and about 1/3 of the shells end up with problems ranging from not going bang at all to giving a barely audible "poot" and then spitting the payload out at anything from barely enough velocity to clear the barrel to maybe less than 1/2 the velocity the payload is supposed to have.

    The 1301 is generally pretty agnostic about ammunition, but it's still possible to have ammo that has issues or doesn't work well in the gun.

    Since your main parts seem to be there and in proper working order, I'd suggest trying a different type of ammunition and running a couple of hundred shells of it through the gun. If the exact same problem persists with two or three types of ammunition, it's likely something up with the gun. If it doesn't reappear with two or three other types of ammo and only those slugs, you've narrowed it down to possibly that specific slug load. If you like that slug, try a quantity from a different production lot and see if the problem persists. If it doesn't you've narrowed it down to that specific lot of ammo.

    ...and given how hard life has been for ammunition manufacturers lately, a lot of bad ammo isn't an unreasonable explanation.

    By all means, call LTT...but I think they're going to tell you to try running the gun with a few types of different ammo to see how it functions.

    When I run into a gun that's having issues I try running it as fast as I can with as many different types of ammunition as I can. That usually tells me whether or not to start looking hard at the gun.

    As far as a dirty gun goes...a dirty gun means you're shooting it.

    I think that's a problem. The bolt should be closing on its own at that point.

    That right there is one of the many reasons we have a great forum.

    OK, I really should have inspected the shells that got stuck better. Water under the bridge now I guess.

    You guys makes great point about the ammo. I think my strategy going forward will be:

    (1) Monday: Call Langdon and let them know I’m having a problem. Maybe they have some ideas or know of others experiencing the same issue with this batch of shotguns.

    (2) Monday: Give the shotgun a good cleaning and lube and see if anything is obviously amiss or doesn’t look right as best as my novice eyes can tell.

    (3) Tuesday: The ammo I was shooting was from a freshly opened case (Federal slugs #PB127DPRS). I have a case of Federal Law Enforcement slugs (#LEB127DPRS) manufactured about a year later than the others that I’ll open and take 50 rounds back to the range with me on Tuesday. If the range has any other slugs I’ll buy several boxes and try them as well. Nearby ranges only allow slugs so until I can get to a range that has clay shooting stations I really can’t try anything lighter.

    (4) If there’s no problems on Tuesday I’ll go back to the range on Friday with some more Federal Law Enforcement slugs to confirm that the problem is apparently ammo related. If I have more problems on Tuesday, I’m comfortable that I’ve tried as much as I should be obligated to with a new shotgun and somebody (LTT or Beretta) is going to have to step up to the plate and make things right.

    You’re explaining this great but I’m too dense to follow it. Last picture attached that I think shows what your referencing.

    I’ll post updates as the week goes. Again, I don’t mean to sound like a broken record but I cannot thank you guys enough for taking the time to comment and provide advice and suggestions. It’s really been a big help. This shotgun was a huge dollar amount for me, not just the shotgun itself but the associated accessories (Aimpoint, light, mounts, etc), so it has been weighing pretty heavy on my mind that I had these malfunctions right from the start.

    I think what TCnVA was referring to was to remove the barrel and look down from the end to the front (breach to muzzle) to see if the ejector sticks out enough.

    As for stripping the gun and reassembling, make sure the barrel, foregrip, and endcap are in place and tightened down. I ran into a problem do to operator error when I first took my gun to the range. I’d pull the trigger on alive round but no boom and no primer strike!!! Turned out I foregrip wasn’t fully seated when I tightened down the end cap. After giggling the grip in place, I was able to do almost 1/2 a rotation of the end cap to get it to seat fully. Problem solved!

    I’ve now drawn a witness mark on the endcap to ensure it’s fully seated after every tear down.

    Was the shotgun properly lubed or was it bone dry?
