You have to resize the brass. If not you will not be able to have enough neck tension to hold the bullet in place to crimp it. If they are going back into the same bolt action rifle then they can be neck sized a couple of times before you will have to full length resize them again once it gets difficult to close the bolt on a loaded round.

For a Lever or pump action to feed the rounds properly you will more likely than not need to full length resize every round ever time or they will not feed properly.

As to the crimping part if they have good neck tension measure them. Load them till the magazine is full. Carefuly work the lever in a safe place, with the weapon pointed in a safe direction. Chamber, and extract each round. Measure them again. If they more than .02 inches deeper then a light crimp would be reccomended to keep them from setting back.
