The 6.8 and the 7-30 have the same base diameter .421-.419"

Shoulder diameter is the same .401"-.399"

OAL is 1.686" for the SPC and 2.040" for the 7-30

The 6.8 is loaded to 53,000 psi, the 7-30 is loaded to 40,000 CUP. There is now real good way to compair PSI and CUP, but the 6.8 is loaded to a higher pressure than the 7-30. Compairing a bullet of equal weight like the 130gr the 6.8 tops out at 2,300 fps and the 7-30 tops out at 2,500 fps. Going by data and drawings in the laod manuals.

TC whats a 6.8 "long"?
