is the 7600 capable of being safe with max loads in calibers like the 280 remington?

The 280rem/7mmRemExpress was standardized at a lower pressure than (for example) the 270win specifically to accomodate the design of the 7600/7400 rifle, so I'd have to say No, you cannot use max loads.

Not that you are likely to "blow up" the rifle, but because there will be functional difficulties, particularly in regards to case extraction.

I agree with ADG but that doesn't mean you can't do a little testing by approaching what you consider a max load in reasonable increments and see what happens.

Unless you full length resize, feeding (bolt closing)might be a problem. Be adventuresome. See what happens, or not. roger

As the 7600 is pump operated I see no function problem. I shoot hot loads in a 7600 in 35 whelen. In fact they make the shell eject very smoothly by holding the forestock and letting the recoil do the extraction work-- then a move foreward and you are ready to shoot again.

280 full loads should not be a problem in the 7600 as long as you follow normal reloading practices. For comfort level, the 7600 is available in 270 Win.

In my personal rifle in that class, a "sportsman 74"I have never actually has a failue to extract.

I have had feeding failures, because it seems that my rifle has a terribly tight chamber.
The rifle will not close on many lots of factory ammo
and for my own reloading I must use the RCBS dies originally made for the early BAR sporting rifles
Not "small base", but what RCBS once refered to as "Special small base" dies.

If it weren't for the fact that the rifle is very accurate and consistant with it's favorite load of 49.5gr of IMR4064
behind a Nosler Ballistic Tip I would find loading for it's persnickety chambering to be odious and annoying.

but it's hard to not like a rifle that shoots better than some bolt rifles I've had the misfortune to own (however briefly)

I think the remington Semi-auto's and pumps get a bad rap that they don't completely deserve.

In your specific case with a pump you don't have to worry about Gas port pressure, so you aren't restricted from using the slowest or fastest propellants and battering the action.

If you do go too far you'll just have "sticky extraction"

On an autoloader it'll belch nasty looking flames straight up (out of the hand guard) and potentially the action can yank
the rim off of the shell.
I doubt that you'll manage that feat by hand... and I'd regard that as a good thing...

I reload for a friend's 7600, and I own (now retired) a 7400. When I approached max. loads in the 7600 in 30-06 we found the action on a bench wanted to open on its own. Accuracy was OK and recoil wasn't much different from factory. We backed it off 1.5 grains, accuracy was much improved as is normally the case anyways. I believe it's OK but then again, what do you really accomplish? The rifle takes a beating for no real reason.

In the 7400, also 30-06 the bolt came back quite hard at max charge and didn't sound the same. I backed it off as well and it operated like all others.

If you rest the rifle and hold onto the slide it will try to open but this is only happening after the rifle has recoiled. My .223 pump will do the same thing but if I put my hand on the buttstock it eliminates this phenomenon.

Back to the original quastion yes the 7600 will digest anything that's loaded to SAAMI pressure specs

That would be a legit argument except for one tiny little fact. You can also get a 7600-7400 in 270win

Precisely.....and if the gun will handle the .270 it will also handle the .280 and the .30-06 loaded to the same pressures....

The Remington pump is a very strong action!

It Happened when the 760 first came out in the early 50s.

Police inspector Wagner ,later chief Wagner of the Cleveland police dept. leaned forward into his new mod.760, 30-06 and pulled the trigger.

We all heard a definite CLICk fallowed shortly by a loud and different sounding bang. The bolt was blown back and the action split. Wagner did not have the magazine in and a large part of the cartridge case blew down, went through his vest, his shirt, slid along his skin, exited his pants after going under his belt just missing his privates.Inadvertantly the pressure he had on the forarm had started to unlock the bolt and the hang fire finished it.

We dug another piece of the case out of a tree his was using to steady himself.

Remington replaced the rifle at no charge. If I had to guess I would say that was about 1952 or 53. roger

He lost a little blood and some dignity but was other than that OK.

If YOU consider it to be a less than legit argument complain to remington because that's what THEY said about their development of the 280rem cartridge.

So any contradiction is THEIRS.

my 7mmRemExpress was a 700 bolt rifle.
I'm sorry I sold it because now the
bolt rifles marked that way (instead of 280Rem)
sell at something of a premium.

I agree the action is "strong" and the 760 has advantages (not including the "Advantage" Roger mentions) over the autoloader. (as mentioned above)

But yeah, the action opening on a 760 is a function of the rifle (and shooter) sliding forward in "Recovery" from recoil and opening the action.

I'd still avoid "abusing" the action with loadings that are completely safe in a 700.

Then again the only factory Remington loads that don't crater the primers and leave pronounced ejector hole marks on the brass in my rifle were the box of "accelerators"
that were left over from my uncle and I was only firing them to "unload" the brass for reloading. (unloading them with a collet bullet puller proved impossible and a kinetic bullet puller an exercise in frustration)

You can "push" your loads if you choose, but I would not do so in either a pump or an auto.

As I said the main advantage to the pump is that it doesn't mind the really "slow" burners
like 4831 that the auto definatly dislikes...
