Since I don't have another 6.5mm gun, I guess I'll sell my remaining bullets (or send to sneaky one for a "custom bullet")...
As Sneaky said my GM chamber allows a bit more velocity and with the 129gn Interloct running to 2618fps over 31.6 gn CFE 223 and the 130gn Gameking getting 2581 over 31.3gn CFE 223. The 100gn TTSX got 2950 over 34.1gn CFE 223 and the 123gn A Max runs at 2700fps over 32.6gn CFE 223.
None of these load are anywhere nearing compression
Please note. These loads are for my Grendel Max chambered rifle and are not to be used in a standard Grendel chamber. Cartridge over all length is also extended to 2.405 which adds to the cases available powder capacity
