Had associate use bore lite and checked chamber on my old faithful 700 Rem in 7 mag. Advised that erosion is in the barrel. Is it advisable to have .25-.50 take off threads and rechamber ? appreciate comments
 
If throat erosion has progressed to the point that performance is affected, a barrel can be set back and rechambered. Might need more than a quarter to half an inch. Significant erosion may extend further than half an inch.
This procedure might well restore accuracy for a while.
However, unless you can do the work yourself, cost is going to be a factor. It is not quite as much work as threading and chambering a blank, but it isn't that much less.
On a Remington, the shoulder will have to be moved forward. The threads will have to be picked up and cut toward the new shoulder. The counterbore will have to be cut. And the chamber will need to be reamed. This all has to be done with precision.
 
I'd take it with a grain of salt...just looking at it with a bore light? Borrow a boresope if you can and even then as other have said if it ain't broke don't fix it. Best and worst thing I ever got was a borescope lol.

How does it shoot?

If the accuracy is fine leave it alone.

There is no way to just take off a half inch from a Rem 700 tenon. The recoil lug surface would end up in the middle of the threads. The only way to do it would be to completely remove the tenon up to the recoil lug surface, which is at least 3/4 of an inch and maybe more.

OP - someone telling you then can remove 1/2" from the back end of a Rem 700 bbl is completely full of it and is trying to soak you for money.
Someone else noted that the work on an old barrel is essentially the same as the work on a new barrel. If the rifle really isn't shooting and needs some work then you'd be best served by installing a new barrel.

Using .500" as a reference, the shoulder is moved forward that much. Pick up the existing threads, and cut threads toward the shoulder, leaving a cylindrical portion for the recoil lug. Shorten the barrel a half inch and cut the counterbore. Ream the chamber to depth.
Setting a barrel back may or may not be worthwhile or worth the cost.

Regardless, you'd still have the thread undercut groove in the middle of the threads. Talk about janky.
