Greetings again,
I remembered that Charles Benke had done some load testing on the 6.5x68 which appeared in Handloader in 1990. A lot has changed since then and most of the projectiles would not be used in the cartridge today. The full load data is available on load data dotcom. The data would not have been pressure tested and his load for the 140 grain Sierra HPTBT at 65 grains of H4831 for 3,150 fps seems pretty hot to me. The cases were RWS and the primers Federal 215 barrel length 22.3 inches. ADI, in their 2000 guide, lists 63 grains of AR2213SC with an unspecified 140 grain projectile for 2,993 fps in a 25 inch barrel for comparison. Hodgdon does not list the 6.5x68 so I doubt if any of this data has been pressure tested.
Regards Grandpamac.
