[QUOTE="hammertyme, post: 576120, member: 12863"] Very interesting stuff here. I have been running the Gibbs wildcats off and on (mostly on) since the mid "90's) The times it was off is when I got tired of forming new brass do to loss of primer pockets trying to get appreciable velocity increases over the standard 6.5 X 06 or 270 cases. I mistakenly put a 40 degree shoulder on the first reamer I made and found pressure before the velocity increase I wanted. After that I took the RWS 7X65R case and had a reamer built from those case dimensions and with a 30 degree shoulder and a .250 neck length. Now, five full years of this later combination I have yet to loose a case and I went from an Average speed with 130gr Accubonds of 2855 and good case life to 3100fps with the RWS case and the same bullet with great case life. I even use the 280 RWS case and nearly get the same results. I am convinced that the rim on the super tough 7X65R RWS is what is keeping the primer pockets nice and snug. The rimmed case feeds great in my WSM bolthead of the Savages. The 6.5, 7,30 calibers came as a result of the parrent 338 Gibbs of which I and my wife have been hunting with for the past 5 years. My experience with the tough cases is the 30 and 338 Gibbs will duplicate the 300 H&H and 338 WIN Mag velocities with good case life. The throw away cases from factory ammo today have not been good for me. Neal [/QUOTE]
