My suggestion would be to simply take one of your fired proper length cases and full length resize it.
Then without seating a new primer or charging the case with powder, (empty unprimed case) seat a bullet long by backing off on the seating die.
Insert the case in the gun and close the bolt, which will seat the bullet by jamming it into the rifling.
I would then readjust the die by at least one full turn on the seating depth adjustment and reseat the bullet to that depth.
Then use a match to smoke up the bullet and chamber it into the gun.
Rifling marks will appear on the blackened bullet, deeper adjustments can be made untill the marks completely disappear if desired.
Check the final length chosen for magazine length fit if necessary.
No special cases or tools of any kind are necessary.
An alternative method of removing the firing pin assembly from the bolt and seating the jammed bullet deeper until the bolt falls closed with no resistance can also be used.
But for average Joe loader the match smoked system is easy and works very well.
Resmoke the bullet as necessary.

This is the easiest and best way... imo
