The 6,5 Grendel breaks bolts when loaded to pressures that give you the stated ballistics.

You are absolutly correct... it is about the number of rounds/lbs.

My personal choice was the 6x45. Again just a barrelswap.
6mm projectiles from 40 to 107grains and velocities higher than the same bullet weight in the parent 223 cartridge.

For longer range work I chose the 243WSSM.

What is everyone elses thoughts?

The C-Products mags are not that reliable. I do agree that the 7.62x39 is an intresting cartridge, just as the 30 Rem. is an intresting cartridge.

If the 6.5 Grendel or the 6.8 SPC were going to break into military use the had to be able to use the same bolt and mags! (By the way shooting a Beta-C mag is very cool). Also if you want to see what really killed off the 6.5 Grendel or the 6.8 SPC military asperations look at the Sierra or Hornaday catalogue and look at the new .22 caliber heavy weights:

77 gr HPBT also called the open tip match bullet
80 gr HPBT
90 gr HPBT

One might have some problems with the 80 and 90 pills... but I think you get my point. These bullets shoot nearly as flat and hit as hard as the ~90 gr bullets out of the 6.5 Grendel or the 6.8 SPC.
