I regularly use Redding and Forster dies. I use their competition series bushing type dies for both 308 and 6.5C highly recommend them.
Call Redding and speak someone in support and you'll get what you need for sizing, etc. for which bushings to order based on your desired end result / chambering, etc. There's a little bit of math involved and a few variables.
Non-bushing type neck sizing, the Redding dies are excellent, as well the list of others, however I've been preferential to RCBS in years past.
