Re: Pulling bullets
You should not need to neck size your brass after pulling bullets if you use a camlock bullet puller such as the Hornady one instead of using a kinetic puller, and then use the Lee Factory Crimp Die after seating the next bullet. You can totally control the amount of crimp with the Lee FCD. Also, the camlock pullers used in your press saves all your powder with no spillage and it's much faster than kinetic pullers.
I just salvaged 73 rounds of Norma brass loaded with Nosler Partition bullets this morning and by using the Hornady camlock puller it was all over in no time with zero spilled powder. I'll save the Partitions for later, but seated Sierra 140 Gamekings in order to use up the charges of W760 powder. I'll use them at a prairie dog town in order to break-in my new 7x57mm Mauser a bit more. W760 is too temp sensitive for Montana, where temps can go from near summer to near zero in the fall hunting season. Will reload with H4350.
As long as you feel definite tension when loading the next bullet, you are good to go after using the Lee FCD. The whole idea of the Lee FCD is to stabilize your bullet against unwanted movement in handling and impart a consistent backpressure for uniform powder ignition. If you have a long throated rifle like a classic 7x57 Mauser or 6.5x55 Swede and use light bullets but want to be within reasonable distance of the lands, you will have little case neck purchase on your bullet. Using the Lee FCD gets you a decent grip on the bullet that eliminates bullet shift during handling.
