7400 ??

[southernhunter]

i just bought a used 7400 carbin in 30/06 its jamming up.i have only tryed one brand of shells so far but plain on picking up a couple of boxes to see if that helps. i know lots of ppl hate them i have one that my dad gave me thats never jammed .but this is the second carbin i have had that jamms the other was the new 750 model in 308.i like the feel of the gun more than any other rifle i have ever owned so i would hate to see it go.any one now any thing about them other than they have to be super clean .

shunter,

Here is an article I found discribing your exact problem, it mentioned both the 7400 & the 750. Not sure which way yours is jamming, ejection or live round pick up, but this should help.

If your Remington 7400 or new 750 is jamming there is a very SIMPLE fix! The first thing you must determine is the type of jam you are experiencing. If your auto loader is NOT ejecting a spent round then this fix is the solution to your problem, If your auto loader is ejecting the spent round but not driving a live cartridge home then this is not the remedy and you should first try a new clip and a thorough cleaning (with one exception which i will explain later.)

If your Remington auto loader is CLEAN and well LUBED and you are not ejecting the spent casing then you need to remove the fore arm and with a quality pair of large sharp jawed of diagonal wire cutters remove ONE coil from the return/mainspring. Place a piece of clear shipping tape on the receiver so that the edge of the tape covers the bolt handle slot just enough to cause the bolt handle shaft to "dent" the edge of the tape when it is pulled fully to the rear of the receiver. This is the gauge to let you know when the bolt has been fully thrown to it's most rearward position in the receiver by the gas operation system. Your bolt MUST reach it's full rearward movement to engage the live round in the mag!
Load your clip with 4 rounds and one in the chamber to cause full pressure and drag on bolt.
Fire the rifle. If it did not eject the spent round, load a new round and "dent" the end of the gauge tape then clip another coil off and repeat the procedure.

Important to know is that you must stop clipping coils as soon as the tape is dented showing full rearward movement of the bolt! I have repaired many 7400's and a couple of the new 750's with this method and the worst that can happen is you clip too many coils and have to replace the mainspring and start over.
As long as the spring clipping was stopped as the bolt fully reached the rear of the receiver you will have ample spring pressure to close the bolt and load a new round.

P.S In the begining I mentioned an exception to the rule and here is the explanation.

If your firearm is ejecting a spent round but not picking up a new one then this fix will also work because most likely your problem is that the the bolt is traveling far enough to eject the round but not fully to the rear to pick up the live round.
Use the tape "gauge" at the rear of the bolt slot to determine if the bolt is traveling fully to the rear.
This method will put an end to the term JAMOMATIC.
I have never over cut the spring by cutting one coil and testing ONE at a time. Every Rem. auto loader I have repaired in this fashion has stayed fixed and functioning perfectly.
good luck.

shunter,

I should have mentioned to give the gun a complete and thorough cleaning, also check the gas-metering orifice in the gas piston where it fits into the inertia block to make sure it is functioning properly and not sticking or plugged with debris.

Good luck

That's why I shoot the 7600 pump. Basically the same rifle, but don't have the ejection problems. I just bought a 7600 Carbine in 30/06 a couple months ago. I have had a 742 in 30/06 that jammed also. A friend of mine bought a 7400 in 270 and it jams ever so often. Go to a pump, and you will never look back.

Thanks

awful lot of problems with some models of remington rifles
it seems like



just saying.....

The autoloading rifles from Remington have always been plagued with jamming issues, cold weather freeze up issues, etc.

Ive had a 7400 for 6 years and have never had any problems. I have only shot core lokt and hornady.

Not ever one of them is a dud, but overall the track record is not impressive.

a lot of the guys in the family have had them and loved them where talk 7 are 8 guys.i have one that has also been a very good rifle for many years.but theres a but .i have had two carbines that jammed every third shot and for me its so sad because i love the littie guns in every way.i also have read all the bad on the web about them too. the carbine i have new is a 7400 and its like brand new showing no signs of wear any where.i cant understand why its jamming. i have try cleaning ,different clips,ammo, there are only two things i see that might be a problem ,the extractor is loose and moves around really easy in the bolt .my other one does not. and the rails are much looser than my older one as well.not sure if this is the root of my problem or not ,what do u all think ? this is my last shot at the littie short gun.if i cant get it to shoot then i'll never own another.

Will it eject sheets manually, meaning if you work the action by hand will it shuck a shell and pick up a new one without problems????

If so, then the problem lies in the retractor spring being to stiff to allow the bolt to open completely enough to allow the spent shells out and not pick up a new one.

The tape test is a good way to tell if the bolt is cycling properly when the gun is fired.

[FULLDRAWXX75]

I forgot to mention, the reason it may happen randomly is not all factory ammo is perfect..........some are short charged on powder and don't produce enough recoil to properly work the action. This would not be noticed with a bolt action, pump or lever action as they are mechanically cycled.

[southernhunter]

yes it worksfine by hand, i read the tape test but really didnt understand it fully could you break it down ? i would like to try that

 

[FULLDRAWXX75]

Ok,

The slot on the side of the receiver where the bolt tab pulls back into, at the very end (closest to the butt stock end) place a small piece of masking tape perpendicular to the slot just so slightly forward of the end of the slot so the bolt will make contact with the tape and wrinkle it when it retracts reward completely.

What you are testing is to see if the bolt is actually opening up completely when the gun is fired. Unless you have a high speed camera this is probalbly the best method.

I would pull the bolt back manually, then let off just a smiggin, have someone place the piece of tape across the end of the slot so it just touches the bolt tab, then very carefully (not to touch the tape) load a round into the gun and shoot it.

See it the bolt retracted and made contact with the tape, if not problem solved. Bolt not cycling completely, retractor spring may be too stiff and will need to be modified slightly as mentioned above.

they get a bad rap cause people dont keep them clean.

 

[HuntingandHarleys]

My 742 Woodsmaster in .243 has never give me any problems. Hope you get it figured out.

 

[southernhunter]

me too. i have seen enough good ones to know they can be good but i have had bad luck with the two but then again they both have been used so ya never know what may have been done to them before hand.my dad has a 742 and its a good gun .theres not another hunting cabin out there like them that i know of ,i guess i could cry and plead to my wife till she let me buy a ar -10 , i am kinda old school and like the traditional looking hunting rifles a littie more.any ways thanks for the post and the help i will post back and let ya know how it goes though it may be aftet chirstmas before i try anything else.

What load do you shoot??

I don't have a Rem 7400 but I've had a 742 in 30-06 for over 30 years. I had the same problem you wrote about, no mater what I could not get it to work right. At the time I was shooting 150 gr bullets and the store was out of them. I bought some 180 gr bullets and I never again had any problems with it no mater the brand. I stayed with the 180 bullets and have never had another jam in all these years. That rifle has taken 5 of my 8 largest bucks.

Before you start trearing the gun apart try a 180 gr bullet, fire several of them and see if they work.

That's why I shoot the 7600 pump. Go to a pump, and you will never look back.

Ditto My 7600 has yet to jam!!!! :grin:

imho i would never have a semi auto rifle, unless it was a BAR

 

[southernhunter]

i am a gun nut like most of us on here .i have plenty of deer rifles ,i would love to have a pump but then i would still want the semi auto too .my dad told me years ago to get one gun and stick with it ,but some how i never have seen a gun yet i didnt want to hunt with . heck i have been know to carry more than one rifle to a stand just in case i get more than one shot,"i know dum crazy what ever you want to call it i just love guns !!! my wifes trying to get me some help .

you must not have ever shot an M1A or a DPMS LR308 before then

 

[WHITMAN]

i actually have, i just don't care for an automatic deer rifle. just my personal preferance.

 

[huntinman]

Mr Big, big difference in a Rem7400 and a DPMS LR308 and a M1A. A friend of mine at work were just talking about the M1A yesterday. I would like to have one, but the cheapest I have seen is 1500 up. The DPMS isn't far from that price either. I have a DPMS Panther Special 24" Bull barrel. And I also have the R-25 (Camouflaged DPMS basically) in the 243. I have owned a 742 in 30/06 and afriend of mine has a 7400 in 270. It is a one shot rifle, so you better make the first shot count, cause no guarantee you will have a second shot before clearing the jam. I currently own 6 of the 7600 pumps. 2 30/06 (1 carbine), 270, 2 25/06, including the Kool Blue limited edition (250 made) and I just picked up a 243 this evening I have been looking for for a long while. This one is in synthetic. All the others are wood. 3 of them have had trigger jobs.

JMO that the 7400 and the 7600 are basically the same guns. The 7600 barrels are free floated. Most 7600 will cost 100-200 more than a 7400 (used). It is worth the extra money to me to have something that has a great reputation for being flawless in the woods. Everyone has an opinion on likes and dislikes.

I can't remember who started this thread, but if he is in the area and would like to shoot one of the guns, I wouldn't mind at all. Just PM me and we can set it up.

The 7400 is an auto, the 7600 is a pump action.............not basically the same gun at all.

huntinman,i would love to have a 7600 pump. i would still like it if my 7400 would shoot,i really like the semi autos,i have heard the good and bad ,like i said before i have one thats been a great rifle but then i have had two that made great clubs to beat deer with. lol.the black guns are really awsome but just too high and the browning bar isn't made in a carbin. that i know of.so that puts me right back with the old remington.i think i will start looking around for a 7600carbin in a 308 or 30/06 though. thanks

 

[huntinman]

DUH, I know the difference in a pump and a Semi. I was just saying that if you hold both rifles, they both have the same basic contours, saftey's in the same places, clip fed, barrel length, the way the scopes mount etc..........Other than the actions, the barrel on the pump is free floated, as the semi is not.

Keep looking on Gun Owners Club for these rifles. Usually 400 and up is the going price. I bought my Carbine and my 243 off of that website. Some of it is overpriced, but you can find some deals, and most will negotiate a little. Good Luck.
