Re: Help with reloading
I highly recommend the Wilson case trimmer and case holders. For cases like 308 that have relatively little body taper, they have separate case holders for fired or unfired cases. Some users have reported being able to use the fired holder for both. For most cartridges, there is only one holder for both fired and unfired cartridges. Simple, robust, very accurate, easy to use, and inexpensive.
Sinclair sells a micrometer adjustment for it that is really nice, but not necessary.
