Felt sorry for a young guy at work who was haveing trouble with a Remington 742 30/06 semi auto. Gun would not unlock after firing. Long story short, I have it back in time and there is no drag or hang ups in the complete cycle of gun / manually. I forgot how much of a pita these are to work on, someone kick me in the ass the next time someome asks to repair one please.
Test fired it before I began work on it and it went boom but would not cycle back. Got empty case out and of course the lip of cartridge was almost gone but the primmer had just about backed out also. Factory rounds used. So, didnt have time to go to range today and its 106 outside. I pulled a bullet and powder from case and slaped bolt forward and let firing pin hit primer. Ejected cartridge out of gun and the primer is backed out about .015 to.02 past flush with cartridge base. Cartridge is tight to bolt fase so it has me wondering why the primmer is backing out even with no powder...just primmer power! Did have to replace firing pin and return spring but the primer pocket is at .055 deep. Is it just the nature of the beast with this rifle or could I be overlooking something. Thanks...
SIGNED, sick of pulling this thing apart

bright flashlight...

turn it over, rack bolt back, look at rails.. if there is ANY "saw toothing" in the rails in the top of the receiver, its junk

tear it down, clean EVERYTHING, oil the snot out of it, and try again..

headspace creep? wasn't there a wrong direction threaded barrel ext on a model?

Normally an under powered load, or, primer only load will cause the primer to back out. Primers backing out of a full house load can be the result of a few things. A dirty or otherwise fouled chamber holding on to the case, preventing it from fully seating against the bolt face can cause the primer to protrude. Bolt lock timing, or, the bolt prematurely unlocking before the pressure is at a safe level can result in a protruding primer. A fouled gas system can cause cycling problems. An over sized gas port can cause problems as well as a stuck or missing gas orifice ball. The fun never ends with these guns!

I sold my wrenches on ebay last week so I never can work on another.....man I hate those things.

When I attended a Remington armor school the Reminton rep there. Said the avg hunter shoots less then 200 rounds in a rfiles life time.

I think the 742 was designed with that in mind.

It's amazing how Many are out there, rem must've sold a million of them around here. when I work at the range for hunter-sight-in, I swear half the guns are 742's. Most gun shops refuse to take used ones in, everyone hates them, but they'll take em out with their green box of ammo and weaver 4x scope and get their deer.

Most people shoot a couple rounds a year than take them hunting and over a life time shoot them very little. So they keep on taking deer each year.

And they have a hard time selling them so they have to shoot them.

If the government wants to ban certain semi-auto's, let them start there.

In another life, I was a Remington warranty gunsmith. These receivers just plain wear out! There ain't no fixing them.

For giggles, you might try sending it back to Remington and see if they will do any repair/replacedment...I doubt they will

I have a friend that has one that started ripping the rims off cases. I would first clean the chamber VERY well. Then I would Flitz it to polish it. Rinse it really well. I used one of those flexible wire rod type things that Stoney Point used to make. Maybe Hornady still does. That is where I would start.

If that didn't work, I would send it to Malm. He has been way too happy lately.

You're correct, they won't.(!)

Contrary to popular belief, the Remington 742 is perhaps one of the best target rifles built. You plant one of these babies muzzle down at 100 yards, you and your friends can compete to see who can disassemble it with the least amount of rounds. How fun is that?

I doubt that a 50 gallon drum of Fitz would do much good...it's the receiver that wears out.

Accuracy specs for the 742... at least used to be 4" at 100 yds...if it did that, it passed muster.

Please accept this nomination for post of the year!

Until the popularization of the AR-15 and all its clones, I used to consider the 740/742 as one of the bastions of North American independence.

I mean, what other country would be nutso enough to invade a continent with one of those crazy machines behind every closet or mud-room door?

They'd have to figger that anyone who'd trust his source of protein and that of his family to one of those things would be daft enough to fight to the death with it...or after it failed to function, even with an unsharpened shovel.

And since it seems almost every American is used to killing deer regularly with theirs, they wouldn't know it can't kill things, and so would kill invading troops without a second thought.

Wow, just got in from work and seen 13 replies. I worked on these when I had my store front shop, and shall we say I'll bet time wise I made .50 cents an hour and swore I'd never do another. Well much water has passed under the bridge from then to now. I know who did real work on these through some of the statements. Just to show I will NEVER do another one I'm going to give it back to him in working condition for FREE. If I ever get back on here about the same topic...PLEASE, someone shoot me! You guys are great, I'm still laughing!

If every 742 killed just one there wouldn't be a lot more to go around.

I don't have a 742 but I do have a 760. A few years ago I killed a deer with it and the bolt would hardly move. Kept working with it and ended up getting an O-ring out from under the bolt. My question is, and I asked Remington this, "where did the O-ring come from? I had had no problem working the action before that or after and it still kills deer.

Right on pdog - As I hope was obvious, I wrote that with a substantial portion of tongue in cheek.

When I used to do a bit of guiding in Alberta for moose, that is what I carried in case we ran onto something less friendly... carried a 742 Carbine .30-06, to be precise. (Also sometimes used a couple of 760 Carbines too, one '06, one '08.)

Also killed the largest of my own moose with that very 742 Carbine, loaded with GI brass and 200 gr. Nosler Partitions. I can't recall the scope brand, but think it was 1.5-to-4X magnification....it might have been a "Realist"?

Can't you just see us crazy North Americans now? "Hey, Ma, some UN troops just parachuted into Jimmie's north quarter...I hears they's packin Dutch chocolate, German beer, French bread, Spanish vino, and kippers 'n them 'Ling-weenie" sausages from Lord knows where. Guess its time for me 'n the guys from the grain pool to take our 740s and go fetch up some more "import" vittles...ain't no bag limit on 'em neither."
