[QUOTE="44-40, post: 2857050, member: 126985"] This is an old thread, but those interested, I have 800 hybrid cases necked to 308Win, 6.5 Creedmoor, and even 358 Win. Regular dies of every brand work just as they do with brass cases. The SS head is slightly undersize...like a small base die, and doesn't appear to expand at 80,000 plus psi. I have reloaded some 4 times with tight primer pockets. The 6.5 Creedmoor will shoot 140 gr bullets to over 3150 fps in a 24" barrel. So any existing 308 caseed cartridge can experience the similar increase in performance...not just the 277 Fury. But the 277 Fury has a great case design IMO and could be just necked up or down to any reasonable caliber with its 30° shoulder for more performance at 80,000 psi...short or long barrels...I'll be checking barrel life and wear as I go with SS and Chrome moly barrels. Checking head space has not moved in the Rem 700 or the RPR 3 lug..the 3 lug appears to have an advantage with high pressure with more lug surface area...but either work if ya don't over do it, as these cases can handle a tremendous amounts of pressure.
