Difference between Rem 760 and 7600?

[Mount Sweetness]

What changes were made, internally and cosmetic?

Much difference in function/reliabilty?

Different bolts and methods of lock-up.

Improvements or cheaper to manufacture?

I would say cheaper production costs. Haven't heard anything bad about the models 6 or 7600 but most guys I know prefer the 742 to the 7400/4 model.

I think more functionality than cheaper. QC mattered more than the $$ in those days, when they switched to the 7600.

The major improvements over the Model 760 were a simpler bolt, which now had four lugs in place of nineteen, and a single unit replacing the breech ring and barrel extension. Smoother operation came from a hardened steel receiver insert mated to a matching lug on the bolt and heavier action bars.

The magazine was redesigned and its release enlarged. The scope mount screw size and screw hole spacing were increased for greater strength, so Model 760 scope mounts will not fit. Both the Models Six and 7600 retained the original Model 760 specifications of an overall length of 42", a barrel of 22", and weight of 7 1/2½ pounds.

Apparently the new 4-lug bolt that replaced the 19-lug interrupted-thread type allowed slightly higher-pressure chamberings, which was why Rem was able to chamber the 7400 and 7600 in .270 Win and step back a bit from their red-headed stepchild .280, or at least that's what I read in a gun mag at the time.

For the little I know, as far as accuracy, there are more similarities than differences. Remington pumps prove that Remington makes good barrels in my oppinion.

My 7600 in 308 groups match ammo around 1 inch. few bolt rifle will do that out of the box.

A little of both really.
When Remington realized that their best selling 742 autoloader was failing from use, they decided that they needed to do something fast to keep their clientele loyal. At one point, Remington offered a trade in allowance for 742 owners if they bought a new 7400. Product recognition being what it is, they knew that sportsmen liked the style of the rifle, and for the most part trusted them. So, to keep up with loyalty, they refined the 742 and renamed it the 7400 (redesigned bolt, mating of the bolt to action bars etc). From a cost standpoint, there was no need to build the 760 and the 7400 with 2 different bolt heads, so they made the 760 into the 7600, utilizing the same style of bolt lockup as in the new 7400.
