Sorry. Been out of town all week.

On the neck-sizing, just bear in mind that .223 headspaces off the shoulder, and every time you fire a round, the case stretches to fill and seal the chamber, which will see the shoulder move also. Neck sizing doesn't bump the shoulder back into spec.

Its up to you, but I personally wouldn't want to fire your ammo. You might get lucky 9,999 times out of a 10,000, but that one time it goes wrong it might ruin your whole day (or your rifle, or your face).

Its perfectly normal to neck size and I cant see how its dangerious? If the round is out of spec on the shoulder too far you wont be able to close the bolt, so it cant be dangerious. I bought some wilson gauges and I check the re-sized case with these, if they are OK I fill them. If not I full resize though my shopping list has a shoulder bump die on it.

You are correct on not firing someone elses neck sized ammo, its not for your gun.
