[QUOTE="RT2506, post: 394031, member: 10178"] LC brass is really thick so after you do neck it down you will most likely have to turn the necks. They will not hold as much powder either so you need to really back off and work up your loads from the suggested loads. Also I have found that 260 Rem cases made from 308 cases have short necks when finished. When my buddy and I made cases for his rifle we used 243 Win and necked them up using a tapered expander ball in the size die. We did make some from 308 cases by just running the case into the FL size die without the expander ball in it. Then run it through a second time with the expander ball in the die. We used WW cases. We lost some cases due to crushing and wrinkling. It would be best to size in steps. I would suggest that if you have access to a 7mm-08 die that you run your cases into them first without the expander ball in the die then into the 260 die. Be sure to check the neck wall thickness and measure with a bullet seated the diameter of the neck against the diameter of your throat in your rifle remembering you need a couple thousands clearance for expansion to release of the bullet.
