Have you cleaned it?
My wife's Model 60, btw, only holds 14 Long Rifle rounds. My older one only held 15. Maybe some other models held more? Or are you overloading it? Should only load it up to the little bullet shaped hole in the mag tube.
Just a couple ideas.
Clean Clean Clean Clean it!!!!!!!!!! then lube it It'll be ok!
I have a Model 60 that I have had for over 35 yrs. Mine like yours holds 18 rds. Give it a good cleaning, lube it up and try again. If you still have ftfs try a different brand of ammo. If yours shoots like mine you will be very happy with it.

This is right on the round count and what to do. Round counts changed from 18 to 15 rounds in the early 80s.Needs a good old scrubbung with break free or such.
Lots of FTE erros are just dirty guns.
YOu have one of the older guns with 24 inch barrel thus the 18 rounds. It was must likely stored with some rem oil or other machine oil and the oils has broken down and mixed with the newly deposited powder residue and is causing errors.
If you own a model 60 the following power point assembly presentation is a most have download.

YOu just need a power point viewer.
Clean it up get a 50 pack of CCI ammo ( my test bed ammo in a 22) and shot it again. It could be a recoil buffer but I don't think so.

I used brake cleaner to clean it, especially the extrator as mentioned before. I also cleand and lubed the tube also. just my 2 cents
