I'm getting ready to buy a set of dies and don't know which one is better for my application.
These dies will be used in my KSwiss 31 7.5 x 55.
Which will serve my purpose best?
I'll be using 308 moly bullets.

    If you neck size only you will reach a point where base expansion will make chambering a issue. It would be best to have a Redding type S neck die with a few different bushings. This is to maximize accuracy potential. Then you would get a separate body sizing die for use about every fifth firing to bring the shoulder and base back to a workable size.

    the lee deluxe die set has a FL as well as collet die. Once base expansion becomes an issue,..run in the FL die and your right back to "ready".

    Try what you like but most people with K31s swear that FL sizing is needed, just as in a semi auto, as the straight pull lacks the camming power of a bolt action and neck sized only rounds bind things up.... so I'd go with full length sizing.
