As for having a model 7600 - made in 1982, I would have to see it to believe it....I do not believe that Remington made a model 7600 in 1982...
Your belief would be wrong then. Remington introduced the M7600 in 1981. Read it and weep.

Read what I tell you and take it as GOSPEL.
Remington Made a Model 760 Until 1981, at that point, they changed the name to a Model 6
The Model 6 HAD a Remington Head-stamp from a round of ammo embedded in the receiver.
In an effort to cheapen the gun, they changed from Multi lugs to the square lugs on the bolt.
The clips interchanged. They also came out with synthetic and plain wood models that year.
The Model is the same as the 7600 - But was not called a 7600.
When people decided that they did not like the NEW Model 6, sales declined and they decided that in an effort not to loose customers, they would change the name to 7600.
7600 sounds a lot like a 760 and people could relate between the two.
But again, they lost so many people with the loss of the 760 that they still did not recover from the change.
The 30 - 06 Govt. model came out more than 1 year ago and they made a special run of them and Grice Gun Shop still has 1/2 of all that were made on stock. The 280 Remington was made in a special run and Grice Gun Shop still has 1/2 of them on stock. The 300 Savage was brought out in a special run and Grice Gun Shop still has about 75 out of 300 made that year.
Before Winchester went under, they came back out with controlled round feeding. In an effort to restore confidence and promote sales. Their effort failed and they went out of business.
If Remington wanted to get back in the game, they will have to bring back the model 760, High Gloss RKW stocks and blued finish.
The Internet might be a good source for information about the battle of Hastings, but is not the best source for information about hunting rifles. Due to the fact that peoples opinions gets in the way of facts.
