Thread: 6.8 SPC

Used to have an AR with the SPCII chamber; dropped a couple of fallow and plenty of goats. I've contemplated the idea of doing a 6.8 Mini action as I still have all the reloading gear and a lot of brass.

It's an effective round, but was hampered by the incorrect chamber drawings being submitted to SAAMI (SPC), resulting in less than ideal performance when it was released to market. The original chamber specs (designed by the US AMU) are known as the SPC II; allows slightly higher pressure loadings and thus better performance. However, most commercial ammo was loaded to SPC specs.

The 90gr Speer Gold Dots work very well, and are the projectile used in the military contract ammo (XM68GD). The 110gr TTSX, 110gr Accubond, 120gr SST, and 110gr HPBT (Hornady) are also solid choices.

To be honest though, I'd go for a 6.5 Grendel; better ballistics, good range of projectile choices, and it's proven. The 6mm ARC looks to be a good choice too, especially with the SOCOM adoption, but the current market options are still limited and shorter barrel performance is still TBD (SOCOM are running 18").
