Author Topic: Remington 7400 jams (Read 1644 times)

Hi,
I have a new to me, but used remington 7400. After cleaning and oiling the gun, to remingtons directions, the gun still continues to "jam" after firing the first round. The spent round discharges fine, but the mechanism doesnt seat correctly, or fully. I have to manuall grab it, and pull it back a few times before it would seat correctly. I am using remington ammo, and have tried several different remington clips. Problem still continues.
Any help would be appreciated, and taking it to a gunsmith is not an option at this time.
Thanks.

What type of bullet are you using, for semi auto's you want a pointed tip. That might be the problem.

Yes I am using the pointed tipped remington ammo.
The spent round will eject, but the breach bolt will sit about a half inch from the correct position. Ill have to grab the operating handle on the bolt and pull it back a few times, let slip out of my fingers and let it seat, or spring back into place. Then I can fire the second round. The other remington 7400 I have used for years worked flawlessly with every type of ammo I could feed it. From round tipped, to pointed, and any manufacturer. I have a note off to remington arms so hopefully when they return from the holiday they can give me some insight.

Thanks...

Unless someone can spare you, call Remington. Even though deer season is approaching or is here, if the gun is in that bad of shape, you need to get it repaired. Either through Remington or a gunsmith. Remington might cover all the costs, however. Good luck and take care.

Thanks for the reply.
I have an email off to Remington and am waiting for a reply. Deer season has passed for me so I have a year to get this fixed.
Thanks again

Well that's somewhat good to know. I am in hunting season now and have three objects that are in need of repair; one of them in the shop. The one in the shop is a brand new Browning Black Ice flash light that for some reason the main 6V Xenon won't function. Then I have two Bushnell products; a brand new pair of H20 Binocs and a 5 year old Sportsman 3-9x32 scope that are both NOT waterproof as the guarantee says. So...lady tells me to send them to Bushnell. Not when I have another two weeks of gun season plus the headache of getting my gun sighted in when I get the scope back. NO WAY. Oh well. C-ya all later!

Check for a burr either on the rotating bolt head or in the lugs in the action. I'd watch the oiling, my experience is Remingtons like dry more than oilly. I have a 742 ADL, my father has a 742 BDL, my nephew shoots a 7400, and 2 friends shoot 742s. All shoot just fine.
Do you load 4 rounds or 5?
I always go with 1 in the chamber 3 in the mag. My dad thinks you need all 5 and his works that way, it creates head aches in others.
If any of ours hung up we would just hit the handle forward, not pull it back. They always closed and were ready to go.
Hope this helps.

Ill recheck for a burr, but I didnt see one the first time I looked.
I have tried loading two rounds, to up to five rounds in the mag to see if the gun habits would change. Still jams. I have received a reply from Remington Arms. They suggested not holding the gun so hard against my chest when I fire the gun, or try different ammo. I have tried 150 grain, to 180 grain with both remington and winchester ammo. I dont think the ammo is at fault. The bolt when jammed, cannot be forced forward. I have to pull it back and let it go a few times before sating correctly.
Looks like time to just start replacing things physically or a good gunsmith.
Thanks for the suggestions.

I wonder if something is hanging up in the forearm? It's all tied together.

607YardKill · « **Reply #9 on:** December 03, 2004, 11:21:54 AM »

I have taken the forearm apart. Everything looks normal. Lubricated spring to remington directions. Didnt see anything that would bind, or anything that looked worn out.

I have 1 trick...Put the loaded clip in and put 1 round in the chamber...Them take the clip out and shoot...Does the bolt cycle fully....try this a couple of times...If it does there might be something wrong with the clips....older clips seem to wear out... new gun new clips.. they are cheap to fix a problem.....but the guys a head of me on here have the other places I would have you look covered......1 to much oil and temps outside thickening oil up while hunting....2 cleaning! gunscrubber everything out in the action....3 old wore out clips.....4 forearm problems.....check if you have a sling on the forarm bolt....5 if all fails call remington...Hope this helps 15 years behind a remington auto...

Sorry to say something that sounds so simple. Just trying to help.

Everything I have read on the 7400 says that you really really have to keep the chamber clean, or it will jam.

Have you bought a chamber cleaning brush (from Brownells) and really scrubbed out the chamber?

Besides trying a different magazine, I would also totally degrease everything, and use a small amount of dry lubricant in the proper places, and then shoot it again.

If you solve your problem with these or any other fixes, would you please post an update to let us know what you did?

Best Regards,

Big Paulie
