Have a hundred or so of once fired brass from my 300 Wby Mag and they seem to measure the same as recommended by my Reloading Manual. The bullets fit snugly in the case and they cycle through the action smoothly. Also have 20 or so brass that seems to have the same dimensions. Unfortunately, I have a case that jammed in the sizing die and I have been unable to remove. The decapper fits into the bullet seating die and then, when replaced by the bullet seating rod, sets the bullet snugly into the cartridge to the correct OAL. So, do I need to run this brass through a new FL die or I am good to go?
Is full length resizing necessary?

Depends on the gun.
For most bolts with strong camming action and unworn extractors neck sizing will work well.
For semi-autos FL size.
Also FL size for guns used for dangerous game where reliability is a must.
I found with our BLR in 308 win we needed to FL resize because the extraction force available through the lever and sprockets was relatively weak.

Better yet, use a stuck case removal kit, or build your own with a tap,a bolt, a socket and a washer.
"Is full length resizing necessary?"
No. Until it is...
You can neck size only if the brass will chamber in a particular rifle. It may even last a few firings before it's too big to fit....then it'll need f/l resizing.
Range pick up brass, and even some new brass may need a f/l resize to fit at all.
Neck sizing only may help accuracy (I'll need to shoot better before I can tell), and it can extend the life of brass by working it less. It doesn't truly replace f/l sizing at the bench though.
