    This is actually an H&R Pardner Pump. Just finally took it to the range to check function and it didn't. :rolleyes: After firing a shell it FTE and tried to jam another shell up in there. Unloaded and put back in trunk. :(

    Back at shop, I've determined the shell hangs up on what I call the "barrel locating lug, etc." (see pic) pulling the shell out of the extractor as the slide is pulled back. The assembly in question is pinned or brazed in but the pins are flush on the outside of the receiver so I don't think it is removable or meant to be.

    Do you think I'll be OK smoothing the edge of the barrel locator? Anyone ever seen this problem?

    To my knowledge, even though marked as H&R, I'm pretty sure those are chinamese 870's.

    No, I haven't see that before. I'm really trying to figure out exactly what you believe is wrong.

    Is the extractor not extracting? Shell too tight in the bore?

    Have you taken the barrel out of the gun and looked at it?

    The gun is apart in the pic. Bolt/slide and trigger group out. I put the barrel back in to take a picture. Green arrows show the barrel, red arrow points to the rim of the shell where the "barrel locator" is blocking the shell from sliding easily. The locator is "pinned" or brazed into the receiver. You can barely see the "pins" (2) on the other side of the receiver and a slight tap did not dislodge them so I didn't push it because this gun is like-new but was only $55.55 "giggle bid" from a local seller on GB. I can see why it is like new because nobody could get it to fire properly. :rolleyes: The seller is a pawn shop and probably took it in on pawn...

    PS: I went to the H&R and Remmy sister sites and sadly they are a ghost town. The barrel locator also incorporates a flat piece of spring steel that appears to put a little tension on the bolt when it is back in the receiver.

    PPS: And with the gun assembled, the bolt stops at this point pulling the slide back. If I pull the extractor off the shell rim, the bolt will go back all the way. Then I can just face the ejection port down and give a shake and the shell will fall out. Everything else appears to function as it should.

    The "major" difference I am aware of is that the barrel loop that goes around the mag tube is in a different location but 870 barrels can be used with a tubular adapter between the 870 barrel loop and the magazine nut. Back a couple years ago when I first got it, I looked for an 870 18" barrel and would have paid more for the barrel than I did the gun so I just shortened the one that was on it... I think the adapter was another $20.

    PS: I just got my nails done... ;)

    I would dremmel it.

    If you want I can look at my 870 tonight and see how it is set up for comparison.

    Out of curiosity/comparison I would like that. Just open the bolt, stick a round in the chamber and slide it back to the point I have in the pics and take your pic. No disassembly req'd. :) TIA!

    +1 what Mike said....

    I had to smooth out the leading edge (barrel locating lug LOL) of the chamber on my 870 Express Super Mag....it would jam up tight before dremmeling and polishing with emery cloth. Low brass hulls were particularly 'special' and jam-tastic...like hold the slide and pile drive the butt into the ground to open it kind of special!

    I'll snap a pic for ya...I've just kept a lil extra oil on the bare metal and haven't seen any rust in the 8 years or so since. It's real smooth now...I love that gun.

    Pic above:
    Bottom left corner of the edge of the chamber you can see a shiny spot.

    Pic below:
    You can see wear spots on the 'barrel locating lug'...I don't recall dremelling that part but I'm pretty sure I ran over it with emery cloth. Nonetheless...indeed a contact point. I wouldn't hesitate to take a hair off and see what happens.

    Thanks for the pics, Mike! :) I'll post some pics of my dremel repair soon so we can close out this thread.

    So I had to get me another "dremel" type tool from HF. $32. I mainly got it for the flexible extension. As you can see, the $5 pawn shop dremel I had was a little too fat to really get into the barrel hole in the receiver to remove metal from the locator. The extension fit much better and could also be used to remove metal from a P80 frame. The 940sc frame in the pic was done with sharp metal files and a little too labor intensive for my liking but came out good... ;) A dremel will expedite the process.

    The extension attaches to the end of the dremel by tightening the collet onto a squared cable end not unlike a speedo cable then the housing screws onto the end of the dremel after the collar is removed. This setup worked well to remove about 1mm from the locator. Then I used some jeweler's files to smooth the ground end. The shell now slides easily past and the repair will be verified at the range the next time we go. A few mag loads of dummies cycled through showed no problems in and out so hopefully that is it... :)

    I broke out the little armorer's stand to ease assembly. Note no hammer because one was not needed. Pins pushed right out and in with the pusher tool fabbed from a broken Ph#1 screwdriver. I ended up returning the dremel kit to HF mainly because it was battery op and they didn't have any spare batts for sale. I used the extension less than a minute. I've since ordered an even narrower handled extension from zamazom for $12. I should note that the extension from HF came not-lubricated and the biggest complaint from users was that it got hot which would make sense... :rolleyes: AND today, while looking in my toolbox side cab for a jigsaw, I came across a fairly new, brand-name Dremel that will fit nicely in the antique box... :)
