So after 700 or so rounds and two mule deer with the 6.8 SPC.

I decided to build the .243 LBC which has the shorter parents case and can handle the cartridge over all length with the heavies loaded at magazine length. Which is 2.300 with my current ASC magazines(6.8 SPC mags).

The bullet I built the rifle for is the 95gr Berger VLD Hunting bullet. If I can get close to 3000 fps with them I will be extremely happy.

What velocity were you running the 6.8 SPC with those two bullets?
Reason I ask is I have a 6.8 AR Performance barreled upper(16 inch) that should be here in a week or so but will be shooting the 120 SST Hornady factory load.
Think the 120 SST will work all right on similiar sized deer for say 50 yards to 200 yards ?
