    Just got ammo shipment ,case of 3006 ball, from cmp.Fired 1st shot and case is jammed tight(won't eject).Tried everything,even bent rod pushing from muzzle end.Anybody had similar problem? How did you clear the casing?

    Rather than just pushing the rod, I'd give it a few taps with a hammer.

    Does the action move or is the case still attached to the bolt?

    Did the extractor slip the rim so you can pull the oprod back and lock the bolt back?

    If yes, segment a wooden dowel that has a diameter that will fit the bore into several pieces. Insert pieces into the bore from the muzzle end. Tap dowels using rubber mallet. You should be able to pop the case loose.

    If the bolt is locked into place because you can't pull the oprod back because the extractor is on the rim, you'll need to disassemble the rifle so you can remove the oprod. Then use the dowel trick.

    Stupid Idea

    I have an idea. What if you spray the case with freeze-it? Would that cause enough metal retraction to knock it lose?

    The extractor rod works fine. Ocabj, that idea sounds like it'll work,thanks.Man,that case is really stuck! Must have expanded upon firing. First problem I've had ,so I'm guessing it was the condition of the ammo.
    Thank you all for your suggestions. I won't be able to get to it until later,and will send update.

    Quatin, I had actually thought of trying that.But I really do not want to do anything that might impact the barrell.I'm not saying it would,but...

    What is the condition of your chamber?

    The rifle fired ok.It did not extract the spent case.the op rod had gone forward with the next round, but was blocked by the unextracted case.I removed the rest of the clip with the remaining rounds(7).I have not been able to remove the case .the op rod and bolt are working as they should.

    I'm curious as to why a rod cut into pieces would work better than the same length rod as a whole.

    MechAg94, I suspect the same thing.

    I'm no expert, but I've personally seen the results of an expanded case fireformed to the interior of a rough chamber. It certainly took some coaxing to remove.

    When you extract the case, perhaps you might want to inspect the chamber a bit closer; it might need a bit of polishing.

    One long rod will most likely flex and break. Several segmented rods will be stronger than one single rod in delivering the downward force.

    I'm thinking and thinking about this and I can't figure out why that would be.

    Because any one of the segments can not flex enough to break.Take a piece of 1/4" dowel a couple feet long,you can snap it easily.Now try breaking a 2" piece.Understanding will follow.:)
  14. MechAg94

    Also, since the individual pieces are already separated, there is no shear (sideways) force trying to break it. If a shear force exists, there are already the separation points to slide on. Also, the existing breaks are flat and clean and allow clean transfer of the downward force to the point you are trying to reach. A long rod might end up snapping at an angle making it worthless for your purposes.

    Snowdog, I have never seen a shell get stuck in the chamber, but I have heard guys like you talk about it. Other than a dirty chamber, I can't think of any other reason for this to happen.

    Not cleaning the chamber after shooting corrosive ball can sure do it. Saw it here locally.

    One of the guys shot corrosive ammo and then cleaned the bore but didn't do the chamber. Next time he shot the rifle, some months later, the first round stuck (just like the incident under discussion) and had to be hammered out. His chamber was a mass of corrosion pits. IIRC he tried to brush out the chamber but the pits were too deep. Had to replace the barrel.

    Best to all,

    Doughboy, email customer service at CMP. If you bought the rifle from them and there's something wrong they'll take care of you.

    Well I finally was able to hammer the casing out,and you all were right--it was a dirty chamber. Tomorrow I will clean it properly and hope for the best.I'll take the blame--I had cleaned the bore with boresnake,and had not been having problems before,but guess I assumed too much.This garand is one of my prize possessions;if it doesn't clean up I will be buying another barrel.Experience can be a harsh teacher at times.Cherish your prize possessions.Thanks to everyone for your input.

    It pays to clean the chamber every time you do the bore. The standard GI M3 tool with the chamber brush on it works great.

    I usually wrap a patch or piece of paper towel around the brush to get all the crud out.
