You typically need a FL die to bump the shoulder back - but back only 1-2 thousandths - so it will again chamber easily in your respective rifle.
In the meantime, you can set also st up [adjust] a FL die in your press so it acts like a neck die i.e. it only sizes the neck; then later re-adjust it in your press to full length size the shoulder back 1-2 thousandths say at the 4th, 8th, 12th reload etc.
In hunting i.e. non-custom chambers, a neck die seldom makes a huge accuracy difference, and one will need a FL die eventually to move a shoulder back.
"After 3-4 loadings, one HAS TO bump the shoulder back on almost all factory chambered rifles as the case will not chamber easily or at all completely."
I don't have that problem, and I shoot a lot. I once, when I was reloading at the range, decided to reload a 308 case until it failed - I neck sized it and quit just after I hit 46 reloads - I NEVER had any problem chambering the case.
If you are having problems chambering a case after 3 or 4 reloads, you are doing something wrong.
