Has anybody measured how much force is required to reseat the bullets after the lube has hardened/adhered? The usual forces to seat or pull are so small compared to the shot to shot variation in chamber pressure that the forces would have to be much larger than usual to make any difference. Do we have any idea of the magnitude of force involved in reseating the bullets? Numbers make the difference between opinion/speculation and finding facts.
In my article on neck tension in Fouling Shot #240 I discussed five different ways that improper neck sizing (too much or too little neck tension) could destroy accuracy.
Too tight -- shaving lead, sizing down the part of the bullet in the neck, upsetting the part out of the neck to a larger diameter, and even bending long bullets.
Too loose -- bullet being pushed back into case before seating firmly into throat, thus ruining"fit"
These are real I have experienced some and have seen all of them reported. Unlike case to case variation in neck tension these cause real degrading of performance. Any one of these might explain Tom's lower accuracy in year one.
