What parent case will you be working from? 308 and sizing down? 30-06? That will make a big difference with your die needs. I don't do 25 super but I do re-form 221 from 223 brass and 25-06 from 30-06 brass. Save basic steps and set up.

Have you measured your guns chamber? You may find it necessary to neck turn your brass to get it to chamber in your gun if you down size the brass because of increased neck wall thickness. I like the K&M neck turn tools and I would recommend the carbide mandrel that inside reams at the same time you outisde turn. If your gun has a generous neck you may get by with just resizing and trimming to length. Fire-forming is easy, just load to the low end of any load spec and pull the trigger. Your best accuracy will come with the second or third sizing.

Good choice in cartridges. I really like my 25-06 and have been toying with the idea of a 25 Super.

Hey, Flashhole
will hope to neck up .243 win cases, havent got a barrel yet, but i have modified magazine and thinking of opening bolt face myself to suit the bigger case ,as it was chambered for 6x50 , it is so hard to find dies for souper over here in Aus..

There's a FL sizer and case trim die on eBay right now and the owner says he will ship internationally. You will still need a seat die.
