[QUOTE="DavidA, post: 1895704, member: 72334"] It just seams to reason that all over bore cartridges at high velocities are going to have to put up with throat erosion and rifling crackling. It just is what it is. Barrels are consumable and pushing 3,100 fps versus 2,850 fps will mean significant degrading of expected barrel life by many factor, (3-4 time) If you are off the opinion that 3,200 fps from say a 108 gr projectile is going to kill faster than a 108 gr traveling at 2,800 fps. Then so be it. Get a 6 mm Creed and call it done. Your just buying barrels faster as a consumable. If you really want extended barrel life than drop down in performance to cartridge that will match the bill like a 6.5 Grendel, or 6 mm AR (a necked down Grendel). A 6.5 Grendel 24" Barrel rifle with a 107 Cavity Back MKS should give you roughly 2,820 fps at the muzzle. At sea level it gets you 1,800 fps and 750 ft lbs of energy to 600 yds. A 6mm AR (easy to load just resize a 6.5 Grendel neck) Shoots 105 gr at roughly at 2,775 from a 20" barrel. Giving you roughly the same ballistics with a little more drop. So say you want minimum 2,000 fps. Cut back to 500 yds. to call it good. That range give you 1,942 fps for the Grendel with 882 ft lbs. It will kill anything listed with a properly placed shot. Just my two cents. You just have to decipher what you really want. Ultrea High velocities and long barrel life are mutually exclusive terms. [/QUOTE]
