When I hear reference to seating a bullet to the lands is the practice literal? If I drop a bullet into the chamber and hold it in place what is the bullet in contact with? The lands and grooves or could it be contacting the beginning of the free bore.
Next question. Is free bore the beginning of the bore minus any land/grooves with the diameter equal to the groove diameter? Would a bullet be able to enter the freebore and actually reach the lands/grooves without resistance?
Can a bullet be forced with minimal effort to actually contact the lands/grooves passing through the freebore and is that when a bullet has no jump or should a bullet become snug up against the freebore and would that be no jump?
I've read about seating bullets with negitive jump. Does that mean the bullet has been engraved by the lands?
The concern I have is if I'm moving back from the lands or the beginning of the freebore or am I on the wrong track.
Is there an illustration some where someone can point me to that illustrates a chamber and cartridge (.223 Rem ideally).
